Convert JSON string to object in PHP

json_decode — Decodes a JSON string. Takes a JSON encoded string and converts it into a PHP variable.

Returns the value encoded in json in appropriate PHP type. Values true, false and null are returned as TRUE, FALSE and NULL respectively. NULL is returned if the json cannot be decoded or if the encoded data is deeper than the recursion limit.

Eg:

<?php
$json = '
    {
        "color":"red",
        "font-size":"12px",
        "background-color":"#F5F5F5",
        "height":"40px",
        "width":"100%"
    }';
var_dump(json_decode($json));
var_dump(json_decode($json, true));
?>

Output:

object(stdClass)#196 (5) {
  ["color"]=>
  string(3) "red"
  ["font-size"]=>
  string(4) "12px"
  ["background-color"]=>
  string(7) "#F5F5F5"
  ["height"]=>
  string(4) "40px"
  ["width"]=>
  string(4) "100%"
}
array(5) {
  ["color"]=>
  string(3) "red"
  ["font-size"]=>
  string(4) "12px"
  ["background-color"]=>
  string(7) "#F5F5F5"
  ["height"]=>
  string(4) "40px"
  ["width"]=>
  string(4) "100%"
}
