Description:
------------
Wouldn't it be nice if the trigger_error function could be called with a user-defined $errline
and $errfile? Imagine you were writing an Abstract Class and wanted to handle class errors
internally. Theoretically, you could retrieve the name of the current error handler by using the
set_error_handler function and then the restore_error_handler function. Then, you could use
call_user_func to trigger a user-defined error. However, if no error handler has been defined
previously, set_error_handler will return null and the procedure would fail alltogether. On the
other hand, calling trigger_error will show the file and line where the trigger_error function was
called (which is very unuseful).
Test script:
---------------
// Get the current error handler
function void ( $errno, $errstr ) { }
$error_handler = set_error_handler ( "void" );
restore_error_handler();
// User-define error
$error_arguments = array ( $errno, $errstr, $errfile, $errline );
// Trigger error
call_user_func ( $error_handler, $error_arguments ); // This will only work as long as an error
handler has been previously set.
// Instead, the following function is proposed:
trigger_error ( string $error_msg, int $error_type = E_USER_NOTICE, string $error_file, string
$error_line );
