Validating JSON

The PHP json_decode function will return a strict null if the string passed into it is invalid json or it can’t parse it successfully. The method below can be used for testing json

$decodedJson = json_decode($json);
if($decodedJson !== null) {
	echo('$decodedJson is valid json!');
}else{
	echo('$decodedJson is invalid json');
}
