How to set PHP not to check undefind index for $_GET when E_NOTICE is on?

Question

When E_NOTICE is set to on, PHP will report undefined index for arrays. I want to suppress this error for $_GET only. Is there any way to do that other than prepend

Answer 1

If you don't want to modify all the $_GET references in your code, you could create your own error handler to PHP, by using set_error_handler function

Example (completely untested, but shows the idea):

function myErrHandler ($errno, $errstr, $errfile, $errline) {
    if(strstr("GET", $errstr)) {
        // suppress message
        return true;
    }

    // otherwise, continue with PHP internal error handler
    return false;
}

set_error_handler("myErrHandler", E_NOTICE);
