Capture flashvars

[drisate]

Hey guys i need to capture the flash vars located in the middle of a string that contains the HTML of an external page.

 

The string to capture looks like this:

 

[...]

var flashvars = {
    'file' : 'http://***pods/lawandsociety/P130631MLJMuñiz-Fraticelli.mp3'
    'width' : '492',
    'height' : '60',
    'controlbar' : 'bottom',
    'dock' : 'false',
    'icons' : 'false',
    'logo.hide' : 'false',
    'logo.position' : 'bottom-left',
    'playlist' : 'none',
    'skin' : 'http://***/wp-content/plugins/flash-video-player/skins/overlay/overlay.swf'
    'autostart' : 'false',
    'bufferlength' : '1',
    'item' : '0',
    'mute' : 'false',
    'repeat' : 'none',
    'shuffle' : 'false',
    'smoothing' : 'true',
    'stretching' : 'uniform',
    'volume' : '90'
};

[...]

 

I need it to be converted into $flashvars[file]

This is what i got so fare:

 

            $script = file_get_contents($link);
            $matches = array();
            preg_match_all('~flashvars\.([a-z]+) .*=.*"(.*)";~i', $script, $matches);
            
            if (!empty($matches[1])) {
                $flashVars = array();
                foreach ($matches[1] as $index => $key) {
                    $flashVars[$key] = $matches[2][$index];
                }
            }

 

All i need is a valide regex

regex isn't really good for trying to parse code. Having said that, you're going to have to make some assumptions and hope for the best no matter how you slice this, short of running the page through something that can properly render the javascript.

 

But here's my take:

 

preg_match('~var flashvars\s*=\s*(\{.*?\});~s',$content,$flashvars);
$flashvars = str_replace("'",'"',utf8_encode($flashvars[1]));
$flashvars = array_map('utf8_decode',json_decode($flashvars,true));

This should (again, taking some liberties and hoping for the best), convert it into a php associative array.

 

Array
(
    [file] => http://***pods/lawandsociety/P130631MLJMuñiz-Fraticelli.mp3
    [width] => 492
    [height] => 60
    [controlbar] => bottom
    [dock] => false
    [icons] => false
    [logo.hide] => false
    [logo.position] => bottom-left
    [playlist] => none
    [skin] => http://***/wp-content/plugins/flash-video-player/skins/overlay/overlay.swf
    [autostart] => false
    [bufferlength] => 1
    [item] => 0
    [mute] => false
    [repeat] => none
    [shuffle] => false
    [smoothing] => true
    [stretching] => uniform
    [volume] => 90
)
