I wrote this to be used on my local machine and works as expected.
| <?php
function extract_url($main_url){
$cek_url = parse_url($main_url);
$prefix_url = $cek_url['scheme'].'://'.$cek_url['host'];
$f = fopen($main_url,"r");
$inputStream = fread($f,65535);
fclose($f);
if (preg_match_all("/<a.*? href=\"(.*?)\".*?>(.*?)<\/a>/i",$inputStream,$matches)) {
foreach($matches[1] as $link){
if(!eregi('mailto:|javascript:|ymsgr:',$link)){
if(eregi("http://",$link)){
$url = $link;
}
else{
$url = $prefix_url.$link;
}
if(eregi('PHPSESSID',$url)){
$url = explode("PHPSESSID",$url);
$url = substr($url[0],0,-1);
}
$output[] = $url;
}
}
}
return array_unique($output);
}
?> | |
here is example of use:
| <?php
$start = time();
print_r(extract_url("http://dontbe.afraid.la"));
$end = time();
echo 'done in '.($end-$start).' second';
?> | |
have fun!
