json php not parsing?

Question

PHP

I am writing a parser for insta, and such a problem, the information on the page is in the script and looks like this

<script type="text/javascript">
 window._sharedData = {};
</script>

So, with the help of regular expressions in php, I get all the json part, but when I try to pass it to json_decode(); she returns emptiness

preg_match( '/window\._sharedData\s=\s(?<data>.*?)\;\<\//m', $result, $mat);
json_decode( $mat['data'] );

Answer 1

tryjson_decode( $mat['data'], true);
