Small problem

IRON_FART

Hi, I made a custom function to handle errors and my problem is that I want to call a variable inside the function from outside.

set_error_handler("errors");
function errors($errno, $errstr, $errfile, $errline, $errcontext) {
	global $date;
    switch ($errno) {
	case E_ERROR:
		$errtype = "Fatal Error";
		continue;
        blah blah blah
		}
$errormessage = 'yadayadayada';
print("$errormessage");
}

print("$errormessage"); only works inside the function. How can I force it to keep its value outside of the function?

Thanks.

What do you mean by "keep its value outside of the function"?

With this:

set_error_handler("errors");
function errors($errno, $errstr, $errfile, $errline, $errcontext) {
    global $date;
    switch ($errno) {
    case E_ERROR:
        $errtype = "Fatal Error";
        continue;
        blah blah blah
        }
$errormessage = 'yadayadayada';
print("$errormessage");
}

print("$errormessage"); will print yadayadayada

But I want to be able to do this:

set_error_handler("errors");
function errors($errno, $errstr, $errfile, $errline, $errcontext) {
    global $date;
    switch ($errno) {
    case E_ERROR:
        $errtype = "Fatal Error";
        continue;
        blah blah blah
        }
$errormessage = 'yadayadayada';
}
print("$errormessage"); // <-- Outside function

With print("$errormessage"); after the closing bracket of the function and still have it print yadayadayada.

Did that answer your question?

Have the function return the message and save it to a variable (or just print it out directly).

function errors()
{
   $errormessage = "yadda yadda yadda";
   return($errormessage);
}

$error = errors();
echo $error;

Since you intend errors() for use as an error handling function, that seems out of point. Just print from the function, with [man]trigger_error/man as appropriate.
