| ===== Proposal ===== | ===== Proposal ===== |
| This RFC instead proposes adding a new option flag value for <php>json_decode()</php> and <php>json_encode()</php>, <php>JSON_THROW_ON_ERROR</php>. When passed this flag, the error behaviour of these functions is changed. Instead of setting the global error state, they clear it (to avoid reading dirty values), and if an error occurs, throw a <php>JsonException</php> with the message and code set to whatever <php>json_last_error()</php> and <php>json_last_error_msg()</php> would otherwise be respectively. <php>JSON_PARTIAL_OUTPUT_ON_ERROR</php> would override and disable <php>JSON_THROW_ON_ERROR</php>, so that generic wrapper functions that always pass the <php>JSON_PARTIAL_OUTPUT_ON_ERROR</php> flag continue to support <php>JSON_PARTIAL_OUTPUT_ON_ERROR</php>. | This RFC instead proposes adding a new option flag value for <php>json_decode()</php> and <php>json_encode()</php>, <php>JSON_THROW_ON_ERROR</php>.
