json_decode() returns null issues

Question

I\'ve an issue with my JSON. It works returns correctly in PHP 5.3 (so I can\'t use json_last_error()), and it returns successfully when I copy string explicitly into json_d

Answer 1

Since PHP 7.3, the json_decode function will accept a new JSON_THROW_ON_ERROR option that will let json_decode throw an exception instead of returning null on error.

Example:

try {  
  json_decode("{", false, 512, JSON_THROW_ON_ERROR);  
}  
catch (\JsonException $exception) {  
  echo $exception->getMessage(); // displays "Syntax error"  
}
