php url 正則表達式用法

下面二款php教程 正則來表達式來處理url匹配的代碼，希望對你有點幫助。

<?php
$url = 'http://www.baidu.com/zongzi/oo.html';
$n = preg_match_all("/http:[/]{2}[a-z]+[.]{1}[a-zd-]+[.]{1}[a-zd]*[/]*[A-Za-zd]*[/]*[A-Za-zd]*[.]*html/",$url,$array);
var_dump($array);
?>

例子

$url = 'http://www.test.com/icons/favicon-54.ico, http://www.baidu.com/bb, http://www.111cn.net, http://img.baidu.com/logo.ico';

$pattern = "|http://[^,]+?.ico,?|U";
preg_match_all($pattern, $url, $matches);
print_r($matches);

輸出結果:

Array
(
    [0] => Array
        (
            [0] => http://www.test.com/icons/favicon-54.ico
            [1] => http://img.baidu.com/logo.ico
        )
