How to check if a string starts with another string in PHP

PHP doesn’t have any built-in function to check if a string starts with a specified string or not.

In PHP, we can use the substr() function to do that.

In this example, we are checking, if a given string starts with string http or not.

$url = "http://google.com";

$result =  substr($url, 0 ,4) === "http" ? "true" : "false";

echo $result;

Output:

true

or we can create our own startsWith() function like this:

function startsWith( $string, $search ) {
     $length = strlen( $search );
     return substr( $string, 0, $length ) === $search ? "true" : "false";
}

Above function usage:

$url = "http://google.com";

$result =  startsWith($url, "http");

echo $result; // true
