a href grabbing - howto get all the links in a document?

[Scallion]

I was wondering, I'm writing a spidering tool in PHP and I'm having some trouble with preg_match and whatnot.

I want to grab all the links in a document. What do I mean by that? Well I'll show you a template of a link and what info I need:

<a href="INEEDTHIS" border=0 class="bob">INEEDTHIS</a>

The only problem is this: I don't know how to get just the two pieces of data I need (url and title text). Also, sometimes links use images as their "title text" - how do I manage that? Grabbing the <img> tag is fine by me, but sometimes it messes up my preg_match.

Also, I need all these in 2 arrays: $url and $title, and I want these two arrays to coordinate with each other.

I've been trying to get this darn regex to work for a few hours, so any help possible is great!

This what you are looking for?

<? 
// obsolute path of the file. 
$filename = 'http://php.net'; 
$data = @join ('' , file ($filename)); 
if (!$data) { 
    echo "there were no data in the specified file."; 
    exit(); 
} 
$urls = array(); 
$links = array(); 
$pos = 0;  

while ($pos < strlen($data)-1)  { 
    $pos =  strpos($data,"<",$pos); 
    $pos++;  

    $lastpos = strpos($data,">",$pos);  

    $tag = substr($data,$pos,$lastpos-$pos); 
    if (!strcasecmp(strtok($tag," "),"A")) { 
        $pos = $lastpos+1; 
        $linkpos = $pos; 
        $pos = strpos($data,"<",$pos);  

        $link = substr($data,$linkpos,$pos-$linkpos);  

        $links[] = trim($link); 
        if (eregi("HREF[ \t\n\r\v]*=[ \t\n\r\v]*[\"\']*([^\"\']*)[\"\']*",$tag,$regs))  { 
            $urls[] = $regs[1];  

        } else { 
            $urls[] = "";  

        }  

    } 
    $pos = $lastpos+1; 
} 
for ($i=0; $i<sizeof($urls); $i++) {  

    echo $urls[$i]."          -        ".$links[$i]."<br>";  

}
