PHP Program To Find Odd Even Number

By 8/08/2018 No comments:

"Find odd even number " is the basic PHP program for a PHP learner. As you all aware, Odd numbers are not divisible by 2 and Even numbers are divisible by 2.

Example :

Odd number: 3, 5, 7, 9,11

Even number: 2, 4, 6, 8, 10

So here I am gonna explain it with a simple PHP program.

Odd Even Number Program :-

<?php

$number=22;

if($number%2==0)
{
 echo "22 is an even number"; 
}
else
{
 echo "22 is not odd number";
} 

?>

Output :-

22 is an even number

You can also do this by defining a PHP function to check a number is odd or even as below -

PHP function to check odd even number :-

<?php
function checkOddEven($num)
{
   if($num%2==0)
   {
     $result = "Even number"; 
   }
   else
   {
     $result = "Odd number";
   }
   retrun $result;
}

echo checkOddEven(43);
?>

Output :-

Odd number

Swap Two Number Program In PHP

By 8/07/2018 No comments:

Swap two number generally is the process of interchange two variables with each other. Just suppose you have X whose value 10 there is another number Y with value of 20. Now if we swap these two number with each other then the X value will change to 20 and Y value will change to 10.

So here I am gonna explain with a simple PHP program.

Swap Two Number Program :-

<?php

$x=10;
$y=20;

echo "Value of x: $x</br>";
echo "Value of y: $y</br>";

$temp=$x;
$x=$y;
$y=$temp;

echo "Value of x: $x</br>";
echo "Value of y: $y</br>";

?>

Output :-

Value of x: 10
Value of y: 20
Value of x: 20
Value of y: 10

You can also do this by without using third variable as below -

Swap Two Number Without Using Third Variable Program :-

<?php

$x=10;
$y=20;

echo "Value of x: $x</br>";
echo "Value of y: $y</br>";

$x=$x+$y;
$y=$x-$y;
$x=$x-$y;

echo "Value of x: $x</br>";
echo "Value of y: $y</br>";

?>

Output :-

Value of x: 10
Value of y: 20
Value of x: 20
Value of y: 10

Armstrong Number Program in PHP

By 8/06/2018 No comments:

"Armstrong Number Program" is the initial program from where most of the beginner developers will start to learn and write code in any language. An Armstrong number is a number that is the sum of its own digits each raised to the power of the number of digits is equal to the number itself.
Here is an example of check a armstrong number in PHP.

Armstrong Number Program :-

Below is the simple PHP program to check a number armstrong.

<?php

$number=153;
$sum=0;
$temp=$number;
while($temp!=0)
{
$reminder=$temp%10;
$sum=$sum+$reminder*$reminder*$reminder;
$temp=$temp/10;
}
if($number==$sum)
{
echo "It is an Armstrong number";
}
else
{
echo "It is not an armstrong number";
}

?>

Output :-

It is an Armstrong number

Process to Install Docker on Ubuntu 16.04

By 8/04/2018 No comments:

Docker :-

Docker is a container management service. The keywords of Docker are develop, ship and run anywhere. The whole idea of Docker is for developers to easily develop applications, ship them into containers which can then be deployed at anyplace.

Docker has two flavors :

Community Edition (CE)
Enterprise Edition (EE)

So if you don't know which one should be install, just pick up The Community Edition (CE) flavor and install as below

Docker Installation :-

Follow the step by step process -

Step#1 :- Set up the docker repository

$ sudo apt-get update
$ sudo apt-get install apt-transport-https ca-certificates curl software-properties-common
$ curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
$ sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable"

Step#2 :- Install Docker CE

$ sudo apt-get update
$ sudo apt-get install docker-ce

Step#3 :- Verify the installation

$ sudo docker run hello-denny

So above process will help you to install

Docker on Linux environment. If you found any difficultly, do follow the Ubuntu installation instruction list all you need in detail.

What is Docker and Why We Use ?

What is docker ?

Docker has two flavors : The Community Edition (CE) and the Enterprise Edition (EE)

Initial Release : March 2013

Mostly use on agile based project.

Reference

Why docker ?

Docker has the ability to reduce the size of development by providing a smaller footprint of the operating system via containers.
With containers, it becomes easier for teams across different units, such as development, QA and Operations to work seamlessly across applications.
You can deploy Docker containers anywhere, on any physical and virtual machines and even on the cloud.
Since Docker containers are pretty lightweight, they are very easily scalable.

For more details : why docker

Docker Terms :

Docker Engine : "Docker engine" is the part of Docker which creates and runs Docker containers.

Docker Hub : SaaS service for sharing and managing application stacks.

( Docker Hub is a registry service on the cloud that allows you to download Docker images that are built by other communities. You can also upload your own Docker built images to Docker hub )

Docker Compose : Docker Compose is a tool for defining and running multi-container Docker applications. It uses Yaml files to configure the application's services and performs the creation and start-up process of all the containers with a single command.

Using Compose, it is basically a three-step process.

Define your app's environment with a Dockerfile so it can be reproduced at anyplace.
Define the services that make up your app in docker-compose.yml so they can be run together in an isolated environment.
In the end, run docker-compose up and Compose will start and run your entire app.

For more information read: Docker compose

Docker Image: There everything is based on Images.

Docker file: The Dockerfile is essentially the build instructions to build the image.

For more details : Docker file

Docker-compose.yml : Config. Application’s services.

How To Set Custom Variables With DataLayer in GoogleTag manager (GTM) ?

By 7/22/2018 No comments:

The most common problem for GTM is to setting up custom variables with dataLayer and make that dynamic for your JavaScrip tag.

So here I am gonna explain it with an article. follow whole process for setting up custom variables for your custom JavaScript tag.

I have already explained about GTM or its overview in my one of article. You can read that overview of google tag manager here

Setting Up Custom Variable With DataLayer :

To setting up custom variables with dataLayer, developers has to pass the variables from their code.

for an example :

just suppose your JS-SDK required data like eventName & jsonPayload and other parameters as below.

<script>
var _pmp = _pmp || [];
var cb = Math.random()*10000000000000000;
!function(m,d,e,v,n,t,s)
{if(m.pmp)return;n=m.pmp=function(){n.callMethod?
n.callMethod.apply(n,arguments):n.queue.push(arguments)};
if(!m._pmp)m._pmp=n;n.push=n;n.loaded=!0;n.version='2.0';
n.queue=[];t=d.createElement(e);t.async=!0;
t.src=v;s=d.getElementsByTagName(e)[0];
s.parentNode.insertBefore(t,s)}(window,document,'script',
'js/trackmyscript.js?cb='+cb);
_pmp.push(['init','PMP-XXX']);
_pmp.push(['dataTrack', 0, 'event-NAME', {jsonPayload}]); //parameters to e pass
</script>

You can set the datalayer to pass these variables from your code as below-

if your conversion event is of SignUp, then you have to setup dataLayer from your server side script as below-

Conversion Event : dataTrack_cnv

<script>dataLayer.push("event":"dataTrack_cnv", "eventName":"Buying", "jsonPayload":"{"md_prid":"p1234", "md_prname":"myProduct", "cur":"usd"}")</script>

You can also set this dataLayer on Ajax Response & on button click.

make sure you have initialise dataLayer object before the GTM-Tag as below -

<head>
<!-- Google Tag Manager -->
<script>
var dataLayer = [];
(function(w,d,s,l,i){w[l]=w[l]||[];w[l].push({'gtm.start':
new Date().getTime(),event:'gtm.js'});var f=d.getElementsByTagName(s)[0],
j=d.createElement(s),dl=l!='dataLayer'?'&l='+l:'';j.async=true;j.src=
'https://www.googletagmanager.com/gtm.js?id='+i+dl;f.parentNode.insertBefore(j,f);
})(window,document,'script','dataLayer','GTM-XXXXX');
</script>
<!-- End Google Tag Manager -->
</head>

Now its time to create dataLayer variable by that we can pass it to our JS-SDK-TAG.

Process to use dataLayer variables in your custom JS-SDK gtm tag :-

To use these variables you have to create variables in GTM as below -

First give a name to your variable like - eventName, jsonPayload etc.
Now choose variable type to "Data Layer Variable" because we are already set dataLayer variables from code.

It will looks like below screen after choosing Data Layer variable -

Here eventName below DataLyer variable is the already above set DataLayer variabel name.

Now click to save and use your variable into your created JS-SDK tag in gtm -

<script>
var _pmp = _pmp || [];
var cb = Math.random()*10000000000000000;
!function(m,d,e,v,n,t,s)
{if(m.pmp)return;n=m.pmp=function(){n.callMethod?
n.callMethod.apply(n,arguments):n.queue.push(arguments)};
if(!m._pmp)m._pmp=n;n.push=n;n.loaded=!0;n.version='2.0';
n.queue=[];t=d.createElement(e);t.async=!0;
t.src=v;s=d.getElementsByTagName(e)[0];
s.parentNode.insertBefore(t,s)}(window,document,'script',
'js/trackmyscript.js?cb='+cb);
_pmp.push(['init','PMP-XXX']);
_pmp.push(['dataTrack', 0, {{eventName}}, {jsonPayload}]); //parameters to e pass
</script>

Now set trigger to all pages

Publish your container tag and start to track your event.

So using the whole process developers can set dataLayer variable in their website code and pass to GTM JS-SDK-TAG accordingly. Google Tag Manager makes it more easy to track event with a little bit changes in your website.

If anybody found the issue in setting up dataLayer variables from their website or in passing to GTM, can comment here. I will always here for helping you.

How To Work With Google Tag Manager (GTM) ?

By 7/10/2018 No comments:

I found most of the developers having a common problem of adding a tag code, snippets, pixels or script tag to their websites by that they can track events, re marketing, conversions, analytics and more. Google Tag Manager (GTM) introduce to resolve developers or publishers this type of issue. Google Tag Manager (GTM) makes you possible to add or update tags without having help of your developer.

Google Tag Manager (GTM) provides a full control to their users over how your tags are defined and when should fire. GTM quite easy to learn and much simple to manage if you understand the basics and flow of using that. If you're an SEO and you are managing tracking codes of multiple clients then its good time to start with GTM without having any delay.

More in-depth GTM features

Google Tag Manager has a lot more advanced features and details, like layers and setting up administrators/users. You can find information on all Google Tag Manager features on Google Tag Manager’s help section.

Google Tag Manager (GTM) is large Topic, so here I am sharing the full article on basic of Google Tag Manager (GTM)

Start Learning with Google Tag Manager -

Follow below steps to start with GTM -

Step 1 : Login with GTM

To start using GTM, visit the Google Tag Manager login page. When you click login you will find below page

Step 2 : Setup Accounts for GTM

The first thing to do is give your account a name. You’ll want to name your account with the name of your company so that you can find and manage each of the sites you have in GTM. It’s generally recommended that you have one account per company and one container per site.

Once you have your account set up, you will create your first container. Give your container a name and indicate where you want to use the container: website, iOS, Android or AMP.

Click on create once you’ve chosen your container location, and agree to the Terms of Service, you are ready to install google tag manager.

Step 3 : Install Google Tag Manager Container

Next you will be given two pieces of script to put on your site as below:

The Google Tag Manager snippet code has two blocks - one block has script tag on has noscript tag.

The Google Tag Manager snippet code must be placed on every page of your website. Google cautions you not to put code in a hidden iframe and not to use another tag management system while using GTM (It can cause issues).

Once you’ve added your both GTM snippet code to your site, Google Tag Manager is ready to go.

As your containers grow over time, it can get difficult to track all your tags, triggers and variables. GTM allows you to create folders to help you organize. With folders, you can organize your tags in groupings so it’ll be easier to update and manage as needed.

Step 4 : Setting up triggers

Tags typically execute, or “fire,” when a web page loads or when some other user interaction occurs. In Google Tag Manager, you define triggers with tags to tell GTM when a tag should fire. A great example of a trigger is the “Page View” trigger, which can be used if you want to have your tag fire when a specific page loads.

You will want to tell GTM what to do when a certain action is taken by a user. Setting up triggers is easy to do — you just choose the trigger type:

Step 5 : Setting up variables

Variables help define triggers and what data they send. For instance, you could set up a variable when someone goes to a specific page or clicks on a checkout button or download page.

Step 6 : Previewing Workspace

You can test your changes by setting up your GTM workspace on previewing mode.

Step 7 : Remember to publish

Once you have tested your changes to GTM, remember to publish your workspace. your changes will not work until you publish your workspace. So always do remember after added or edited tags, triggers and variables in a workspace, you have to publish:

With a little bit more learning and practising, you’ll find that managing the tracking code you use will be much easier and more efficient thanks to Google Tag Manager.

How to Create a Scroll To Top With Some Delay Using JavaScript ?

By 6/25/2018 No comments:

Here I am sharing the code for scrolling a page from bottom to top with some delay. You can also use that to reach or show first error element box in your specified form.

Show First Scrolled Error Element Box on Submit :-

you can use below jQuery code to scroll on the first error element box on submit -

$('html, body').animate({
                scrollTop: $(validator.errorList[0].element).offset().top-300            }, 2000);

Above code will work for the form group on submit. for an example below -

$("#submit").on('click', function () {

    var validator = $("#form").validate({
        rules: {
           name: {
                required: true,
                maxlength: 50            },
        },
        messages: {
            nam: {
                required: "This field is required.",
                maxlength: "name must be less than 50 character.",
            }
        },
        highlight: function (element) {
            $(element).closest('.form-group').removeClass('success').addClass('has-error control-label');
            /*scroll to first error element box */
            $('html, body').animate({
                scrollTop: $(validator.errorList[0].element).offset().top-300            }, 2000);
        },
        success: function (element) {
            element.addClass('valid').closest('.form-group').removeClass('has-error control-label').addClass('success');
        }

    });
}

Above code will scroll you back to your first error input box with animation.

Animated scroll back to top for a specified element ID :-

If you want to scroll back to a specified element Id on some event then you can use below code -

$('html, body').animate({
    scrollTop: $("#elementId").offset().top-300}, 2000);

.scrollTop() jQuery Function :-

You can also use .scrollTop() function to scroll bottom to top on a page.

Note:- .scrollTop() function does not accept any arguments.

<!doctype html>
<html>
<head>
  <meta charset="utf-8">
  <title>My wep page scrollTop demo with jquery</title>
  <style>
  div {
    margin: 10px;
    padding: 5px;
    border: 2px solid #666;
  }
  </style>
  <script src="https://code.jquery.com/jquery-1.10.2.js"></script>
</head>
<body>
 
<div>Dashboard</div><div></div>
 
<script>
var div = $( "div:first" );
$( "div:last" ).text( "scrollTop:" + div.scrollTop() );
</script>
 
</body>
</html>
