PHP: string contains (case-insensitive)

To check if a string contains another string in PHP in a case-insensitive manner, you can use the stripos() function. stripos() returns the position of the first occurrence of a substring in a string, or false if the substring is not found, and it performs a case-insensitive search.

$string = "Hello World";
$substring = "hello";
 
if (stripos($string, $substring) !== false) {
    echo "Substring found in the string.";
} else {
    echo "Substring not found in the string.";
}
