How to fix preg_match Compilation failed: error?

[adjunct]

i am trying to get preg_match to find links that end in .mp3.
the call i am using is

preg_match('/*.mp3/',$url,$matches);
 

and i am getting the error

Warning: preg_match() [function.preg-match]: Compilation failed: nothing to repeat at offset 0

i fixed that problem i think by doing

preg_match('/.*mp3/',$url,$matches);
 

i am not getting any results now.

this is what it looks like now

$dom = new DOMDocument();
@$dom->loadHTML($html);
$xpath = new DOMXPath($dom);
$hrefs = $xpath->evaluate("/html/body//a");
 
for($i = 0; $i < $hrefs->length; $i++)
{
    $href = $hrefs->item($i);
    $url = $href->getAttribute('href');
    preg_match('/.*mp3/',$url,$matches);
}
echo $matches;

First print matches like an array using print_r(). Echo does not print arrays.

Second, your echo will only print the last things that was in matches. If you want to print every URL, put your echo/print statement inside the for loop.

but will the preg_match statement properly get every url that ends in .mp3?

it does work i was trying to access the $matches array out of scope.
