PHP Program to Reverse a string

PHP Program to Reverse a string - strrev()

The `strrev()` function in PHP is used to reverse a string. It takes one string argument and returns the reversed string.

Here's an example :

Program :

<?php
$string = "Hello, world!";
$reversed = strrev($string);
echo $reversed;
?>

Output :

!dlrow ,olleH

In this example, we first define a string variable `$string` with the value "Hello, world!". We then use the `strrev()` function to reverse the string and store the result in a new variable `$reversed`.

Finally, we use `echo` to output the reversed string, which is "!dlrow ,olleH".
