description: This example shows how to compare strings in Symfony using PHP with `strcmp` and the strict equality operator.
<?php $string1 = "Hello World"; $string2 = "Hello World"; $string3 = "hello world"; // Using strcmp function if (strcmp($string1, $string2) === 0) { echo "String 1 is equal to String 2."; } else { echo "String 1 is not equal to String 2."; } // Using === operator if ($string1 === $string2) { echo "String 1 is identical to String 2."; } else { echo "String 1 is not identical to String 2."; } // Case-insensitive comparison if (strcasecmp($string1, $string3) === 0) { echo "String 1 is equal to String 3 (case-insensitive)."; } else { echo "String 1 is not equal to String 3."; } ?>
