Return Values

This function returns FALSE if wrong error_type is specified, TRUE otherwise.

Examples

if ($divisor == 0) {
    
trigger_error("Cannot divide by zero"E_USER_ERROR);
}
?>

HTML entities in error_msg are not escaped. Use htmlentities() on the message if the error is to be displayed in a browser.
