strcasecmp
(PHP 4, PHP 5, PHP 7, PHP 8)
strcasecmp — Binary safe case-insensitive string comparison
Parameters
string1-
The first string
string2-
The second string
Return Values
Returns a value less than 0 if string1
is less than string2; a value greater
than 0 if string1 is greater than
string2, and 0 if they
are equal.
No particular meaning can be reliably inferred from the value aside
from its sign.
Examples

<?php
$var1 = "Hello";
$var2 = "hello";
if (strcasecmp($var1, $var2) == 0) {
