Trimming Text in a String

[Komodo_Tale]

Another dumb question. . .

I need to isolate urls from strings. I'm trying to remove everything before 'http:' and remove the '</a>' plus everything after that.

Thanks

Something like the following can give you an idea.
$beg = strpos($yourtext, "http");
$las = strpos($h, "</a>");
$yoururl = substr($yourtext, $beg, $las);

You can even use preg_match, better.

I would suggest changing the following line:
$las = strpos($h, "</a>");
To:
$las = strpos($yourtext, "</a>");

Assuming you have the string stored in the variable $yourtext

Good luck!

function pc_link_extractor($s) {
$a = array() ;

$s,$matches,PREG_SET_ORDER)) {
foreach($matches as $match) {
array_puch($a, array($match[1]m$match[2]));
}
}
return $a;
}

$links = pc_link_extractor($listing[1])
print_r($a) ;

foreach($matches as $match) {
array_push($a,array($match[1],$match[2]));
