使用爆炸获得价值

I am trying to parse following string...

IN.Tags.Share({"count":180,"url":"http://domain.org"}

is my following approach correct to get the value of count?

$str = 'IN.Tags.Share({"count":180,"url":"http://domain.org"}';
$data = explode(':', $str);
$val = explode(',', $data[1]);
return $val[0];

Or is there any better way to handling this type of strings? I think it could be done using regex as well.

thanks.

If course I'm not sure if your format will be constant, but part of your string looks like JSON. If always like this, you could do:

 $str = str_replace('IN.Tags.Share(', '', $str);
 $values = json_decode($str);
 echo $values->count;

I would suggest pulling out the JSON by applying this regex to the string: IN\.Tags\.Share\((.*)\. Pull out the first group, and use json_decode: http://php.net/manual/en/function.json-decode.php

That way, you can directly access the data. It will support complex data structures as well.
