Reverse string in PHP

 PHP has a predefined function to reverse a string but we can do this task in with two methods. In interviews there could be a condition that reverse a string in PHP without using strrev() function.

In this tutorial we will learn both ways to reverse a string. 

1. Reverse string in PHP with strrev() function - 

<?php

    $str = "Thetutorialsway";
    echo "Reversed string is".strrev($str);
?>

2. Reverse string in PHP without strrev() function -

• Assign the string to a variable
• Calculate length of the string and assign to a variable
• Declare variable to hold the reverse string
• Run for loop
• Concatenate string inside for loop

<?php
    $str = "Thetutorialsway";
    $len = strlen($str);
    $revstr = "";
    for($i = ($len-1);$i>=0;$i--)
    {
        $revstr .= $str[$i];
    }
    echo "The reverse string is " . $revstr;
?>
