Документация по классу Stringy Показать файл Открыть проект

isJson() публичный метод

Returns true if the string is JSON, false otherwise. Unlike json_decode in PHP 5.x, this method is consistent with PHP 7 and other JSON parsers, in that an empty string is not considered valid JSON.

public isJson ( ) : boolean
Результат	boolean	Whether or not $str is JSON

    public function isJson()
    {
        if (!$this->length()) {
            return false;
        }
        json_decode($this->str);
        return json_last_error() === JSON_ERROR_NONE;
    }
