Perform Case-insensitive comparison of strings in PHP

strcasecmp() is a nice PHP function for comparing two strings case-insensitively.

Note: the function returns 0 if they are equal.

Examples

The examples below both return the string true.

<?php
$var1 = "Hello";
$var2 = "hello";


if ( strcasecmp( $var1, $var2 ) == 0 ) {
	echo 'true';
}
else {
	echo 'false';
}

<?php
$var1 = "lOVe";
$var2 = "love";


if ( strcasecmp( $var1, $var2 ) == 0 ) {
	echo 'true';
}
else {
	echo 'false';
}
