Swap Two Number Program In PHP



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
