1.2.415. Empty Json Error¶
json_last_error() keeps the last error that was generated while decoding a JSON string. To reset this cache to empty, one must run a call to json_decode() that succeed. This leads some code to make an apparently pointless call, just to empty the error cache, and avoid confusing the message with the one of a previous call.
<?php
// This generates an error
$json = json_decode([);
$json = json_decode($valid_json);
echo json_last_error(); // This error is confused for the last call, not the first one.
// pointless call, except to empty the cache.
$json = json_decode([]);
$json = json_decode($valid_json);
echo json_last_error(); // This error is dedicated to the last call
?>
