zend_error()

zend_error() can be used to generate error messages. This function accepts two arguments; the first is the error type (see zend_errors.h), and the second is the error message.
zend_error(E_WARNING, "This function has been called with empty arguments");
Табл. 36-1 shows a list of possible values (see Рис. 36-1). These values are also referred to in php.ini. Depending on which error type you choose, your messages will be logged.
