  • What is the use of the @ symbol in PHP? 10 answers

    • @ is used to suppress any errors that may occur on this line of the code

    http://php.net/manual/en/language.operators.errorcontrol.php

    When prepended to an expression in PHP, any error messages that might be generated by that expression will be ignored.

    I would not recommend using it at all because this may result in failure of noticing some important error/warning and make debugging a havoc. On a production environment use error_reporting setting that will prevent any errors or warning from showing up while on a development server I would recommend to turn on any error reporting

    PHP supports one error control operator: the at sign (@). When prepended to an expression in PHP, any error messages that might be generated by that expression will be ignored.
