Web Content Tips - Part 7: Do you want to get and show all url in a web page? You can use preg_match_all() like this:
<?php
$url = "http://localhost:8048/blog/index.php";
$data = file_get_contents($url);
preg_match_all("/(http|https|ftp):\/\/[^<>[:space:]]+[[:alnum:]#?\/&=+%_]/", $data, $match);
$list = $match[0];
print_r($list);
// result:
//Array ( [0] => http://localhost:8048/blog/tools/js/syntax00.css //[1] => http://localhost:8048/blog/tools/js/shCore00.js
