Question

How to preg-match total_count from this code in php

{
   "data": [
      {
         "name": "Baptiste Chimay",
         "administrator": false,
         "id": "10153820811316460"
      },
   "summary": {
      "total_count": 4956
   }
}

i tried but it didnt get any data

$url = ('the url i want');
                $result = json_decode($url);
    $likes = preg_match("'total_count (.*?),'si", file_get_contents($url), $matches);
print_r($url);

Looks like (partial) json - is that the entire output from that url? — Steve, Jan 12 '16 at 14:40
Please add the entire output. Php has native support for json, so regex is **not** the best solution — Steve, Jan 12 '16 at 14:43

Thats json data, you can use json_decode to create a php array:

$data = json_decode(file_get_contents($myurl), true);

echo $data['summary']['total_count']; //outputs 4956

Just escape the quotes:

preg_match("/total_count\"\:(.*?)/i", file_get_contents($myurl), $matches);
//               here __^

But, you don't need to escape the selmicolon

preg_match("/total_count\":(.*?)/i", file_get_contents($myurl), $matches);

you could also replace the double quotes by single quotes:

preg_match('/total_count":(.*?)/i', file_get_contents($myurl), $matches);

and change the .*? to [^"]+

preg_match("/total_count\":([^"]+)/i", file_get_contents($myurl), $matches);

you could also replace the double quotes by single quotes:

preg_match('/total_count":(\d+)/i', file_get_contents($myurl), $matches);

I would actually change from the `[^"]` to `d+` – mloureiro Jan 12 '16 at 14:46
