How to compare two strings in PHP

Use the PHP strcmp() function

You can use the PHP strcmp() function to easily compare two strings. This function takes two strings str1 and str2 as parameters. The strcmp() function returns < 0 if str1 is less than str2; returns > 0 if str1 is greater than str2, and 0 if they are equal.

Let's check out an example to understand how this function basically works:

<?php
$str1 = "Hello";
$str2 = "Hello World";
echo strcmp($str1, $str2); // Outputs: -6
?>

The PHP strcmp() function compare two strings in a case-sensitive manner. If you want case-insensitive comparison, you can use the strcasecmp() function.
