PHP - Parse String with Regex

If you really want to use RegEx instead of parse_url(), you could try this:

$url = 'http://www.site.com/one/two/var_abcdefg.html?var=123456';

preg_match('#^([^?]*?)([^/?]*)(\?.*|)$#', $url, $match);

$var_1 = $match[1]; // http://www.site.com/one/two/
$var_2 = $match[2]; // var_abcdefg.html
$var_3 = $match[3]; // ?var=123456

No need of regex, PHP has a built-in function that breaks a url into parts : parse_url()

<?php
$url = 'http://username:password@hostname/path?arg=value#anchor';

print_r(parse_url($url));

echo parse_url($url, PHP_URL_PATH);
?>

The above example will output:

Array
(
    [scheme] => http
    [host] => hostname
    [user] => username
    [pass] => password
    [path] => /path
    [query] => arg=value
    [fragment] => anchor
)

Don't use regex for this, see parse_url.
