php preg_match on consecutive tags

I'm trying to capture all Location paths on an apache conf file, to make automatic nginx templates.

The file that I'm reading has something like this

<Location /images/mobile>
    SetHandler modperl
    PerlOutputFilterHandler Apache2::AMFImageRendering
</Location>
<Location /images/otherroute>
    SetHandler modperl
    PerlOutputFilterHandler Apache2::AMFImageRendering
</Location>

I almost got the regex working with the "location" match group, I had the following

$file_str = file_get_contents($conf);
preg_match("/<Location\s+(?P<location>.*?)\s*>.*?Apache2::AMFImageRendering.*?<\/Location>/s", $file_str, $matches);
print_r($matches);

The problem is this only get the first location "/images/mobile" inside $matches['location']

Is there anyway to match all locations, without splitting the string or using preg_match with an offset

Thank you

You're looking for preg_match_all(). This is PHP's answer to the /g modifier of normal regular expressions. The 3rd parameter passed ($matches) will now contain an array of global match sets.

$file_str = file_get_contents($conf);
preg_match_all("/<Location\s+(?P<location>.*?)\s*>.*?Apache2::AMFImageRendering.*?<\/Location>/s", $file_str, $matches);

print_r($matches);
// Array (
//   [0] => Array
//     (
//       [0] => SetHandler modperl PerlOutputFilterHandler Apache2::AMFImageRendering
//       [1] => SetHandler modperl PerlOutputFilterHandler Apache2::AMFImageRendering
//     )
//   [location] => Array 
//     (
//       [0] => /images/mobile
//       [1] => /images/otherroute
//     )
//   [1] => Array
//     (
//       [0] => /images/mobile
//       [1] => /images/otherroute
//     )
//  )
