I have a custom error handler attached to E_ALL PHP errors.
In an external lib the call $row = @mysql_fetch_assoc($this->result); triggers PHP Warnings caught by my handler. Why? Shouldn't '@' make PHP ignore this?
My question: Is there any way I can detect (in my error handler) that '@' was used?
Referencing the PHP Manual on set_error_handler shows
It is important to remember that the standard PHP error handler is completely bypassed. error_reporting() settings will have no effect and your error handler will be called regardless - however you are still able to read the current value of error_reporting and act appropriately. Of particular note is that this value will be 0 if the statement that caused the error was prepended by the @ error-control operator.
So you could do this:
function my_error_handler($errno, $errstr) {
if (error_reporting() == 0) { // called with @
return;
}
//....
}
A quick look into the PHP manual revealed this:

Using the @ operator is considered bad style by quite some people, btw.
