1 Equality Check Ignoring Case in PHP

In this example,

We create two strings named $str1 and $str2 with different cases, such as "Hello" and "hello".
We use the strcasecmp function to perform a case-insensitive string comparison.
Alternatively, we can convert both strings to lowercase or uppercase using strtolower or strtoupper functions and then compare them using == or === operators.
The comparison returns true if the strings are equal ignoring case, and false otherwise.
Finally, we print the result of the comparison.

PHP Program

<?php
$str1 = "Hello";
$str2 = "hello";
$result = strcasecmp($str1, $str2) === 0;
echo "Strings are equal ignoring case: " . ($result ? 'true' : 'false');
?>
