Official PHP 7.3 Migration Guide
- theodorejb 8y agoMy favorite features in this release: * Trailing commas in function/method calls * array_push() and array_unshift() can now be called with a single argument (helpful when using the spread operator) * TypeError now reports wrong types as int and bool instead of integer and boolean (no more "Argument must be an instance of integer, integer given" errors) * Deprecation of case-insensitive constants * json_decode() and json_encode() now support a JSON_THROW_ON_ERROR flag (removing the need to call json_last_error() to see if an error occurred) * setcookie() now accepts an associative array of options, and supports the samesite attribute * More flexible heredoc syntax
