php json_decode not working

You have to use preg_replace for avoiding the null results from json_decode

here is the example code

$json_string = stripslashes(html_entity_decode($json_string));
$bookingdata =  json_decode( preg_replace('/[x00-x1Fx80-xFF]/', '', $json_string), true ); 

php try to decode json

/** Checks if JSON and returns decoded as an array, if not, returns false, 
but you can pass the second parameter true, if you need to return
a string in case it's not JSON */
function tryJsonDecode($string, $returnString = false) {
   $arr = json_decode($string);
  if (json_last_error() === JSON_ERROR_NONE) {
    return $arr;
  } else {
    return ($returnString) ? $string : false;
  }
}

php json decode

$obj = json_decode("{string:'string'}");
