1.2.623. Json_encode() Without Exceptions¶
json_encode() and json_decode() should use the exception system, to detect invalid JSON syntax.
The second argument is a bitmask, and shall include JSON_THROW_ON_ERROR, so that both function may emit an exception when a parsing error happen. That exception can then be caught with a try/catch structure. Alternatively, the error may be check by calling json_last_error() function. It will not be empty if an error is called.
<?php
try{
echo json_encode($response, JSON_THROW_ON_ERROR | JSON_PRETY_PRINT);
} catch (\JsonException $e) {
echo "Sorry, an error occured.";
}
?>
See also json_encode().
1.2.623.1. Suggestions¶
Add the JSON_THROW_ON_ERROR in the second argument.
Call json_validate() on the data, before parsing it.
Check json_last_error() after the parsing, to detect any error
