搜索站点中的文件并将其复制到阵列

Question

I want to search *.rules from this site http://cvs.snort.org/viewcvs.cgi/snort/rules/

and copy the strings of files into an array

how can I do this? for example:

$array=array('backdoor.rules','bad-traffic.rules');

I can use

$str=file_get_contents( 'http://cvs.snort.org/viewcvs.cgi/snort/rules');

but how can I search?

You need to use a regex to get any matches of the source

    $url = 'http://cvs.snort.org/viewcvs.cgi/snort/rules/';
    $contents = file_get_contents($url);
    //Regex to match any links that have .rule in it
    preg_match_all('/<a href="([^"]+\.rules[^"]*)">/i', $contents, $result, PREG_PATTERN_ORDER);
    foreach ($result[1] as $link) {
        //Fetch the link and save
    }

This code will fetch the contents of the web page, and run a regex which matches any link that has .rules in it.

Inside the loop you can then save the files (using file_get_contents , and then fopen, fwrite and fclose)
