How can I convert a string to array?

Question

I have a string like this:

$str = '[{"file_id":"AgADBAADX6oxGyqs0FJLW3rZ3g6_fDnO-RkABB0pg6HTwdv7EqUBAAEC","file_size":1347,"file_path":"photos\/file_2.jpg","width":90,"height":75},{"file_id":"AgADBAADX6oxGyqs0FJLW3rZ3g6_fDnO-RkABIMbRhad2WVdE6UBAAEC","file_size":17588,"width":320,"height":265},{"file_id":"AgADBAADX6oxGyqs0FJLW3rZ3g6_fDnO-RkABHSo-WKlRRfBEaUBAAEC","file_size":18480,"width":330,"height":273}]';

How can I access items in it?

I can use regex to select them, something like /"file_id":"(.*?)"/. But that's not clean at all. Is there any approach to make a array (or an object) of string above?

It's a json string.
You need to decode it with json_decode.
The second argument (true) is to make it an array.

$str = '[{"file_id":"AgADBAADX6oxGyqs0FJLW3rZ3g6_fDnO-RkABB0pg6HTwdv7EqUBAAEC","file_size":1347,"file_path":"photos\/file_2.jpg","width":90,"height":75},{"file_id":"AgADBAADX6oxGyqs0FJLW3rZ3g6_fDnO-RkABIMbRhad2WVdE6UBAAEC","file_size":17588,"width":320,"height":265},{"file_id":"AgADBAADX6oxGyqs0FJLW3rZ3g6_fDnO-RkABHSo-WKlRRfBEaUBAAEC","file_size":18480,"width":330,"height":273}]';


$arr = json_decode($str, true);
Var_dump($arr);

Explode(“,{”, $str); will work for the above.

You will get array value for each file.

This is a very bad solution. It is a json string and should be handled as such. Exploding like you suggest results in an array containing unusable strings
