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");
Table 9.16 shows a list of possible values (see Figure 9.8). These values are also referred to in php.ini. Depending on which error type you choose, your messages will be logged.
