将数组值与URL字符串匹配

Question

I have an array:

$blacklist = array("asdf.com", "fun.com", "url.com");

I have an input string:

$input = "http://asdf.com/asdf/1234/";

I am trying to see if string $input matches any values in $blacklist.

How do I accomplish this?

Sounds like a decent use for parse_url():

<?php
    $blacklist = array("asdf.com", "fun.com", "url.com");
    $input = "http://asdf.com/asdf/1234/";

    $url = parse_url($input);

    echo (in_array($url['host'], $blacklist) ? '(FAIL)' : '(PASS)') . $url ['host'];
?>

Output:

(FAIL)asdf.com
