PHP正则表达式检查匹配的给定URL

Question

How do you check if a given URL matches at least a sitename?

I have:

$url_to_match = 'http://sub.somesite.com/';

I want to say "MATCH found" for input starting with http://sub.somesite.com only.

Any help would be very much appreciated.

Answer 1

Use PHP's parse_url() :

$url = 'http://sub.somesite.com/';
if ('sub.somesite.com' === parse_url($url, PHP_URL_HOST)) {
    // we have a match
}

Answer 2

use parse_url

example:

function match_url($base,$input)
{
    $base_host = parse_url($base,PHP_URL_HOST);
    $input_host = parse_url($input,PHP_URL_HOST);
    if( $base_host === $input_host ) {
        return true;
    }
    else
    {
        return false;
    }   
}
$base_url = 'http://sub.somesite.com';
$input_url = 'http://sub.somesite.com//bla/bla';
echo (match_url($base_url,$input_url)) ? "URL matched" : "URL mismatched";

Answer 3

I think you need to tell us what you are doing since this request makes no design sense.

However, to answer the question.

if(strpos($url_to_match, 'http://sub.anothersite.com/bla') !== FALSE) print 'bad string';
