Declaring a summary of the parameters in the PHP kernel Zend

The basic way to declare the parameters of an extension function is as follows:
Zend_begin_arg_info (name, 0|1)


Zend_end_arg_info ()
The definition of each parameter can be one of the following macro definitions:
Zend_arg_info declaring common parameters
Zend_arg_obj_info arguments for declaring object types
Zend_arg_array_info arguments that declare an array type
Zend_arg_pass_info (Pass_by_ref) pass_by_ref is 1 o'clock, forcing subsequent arguments to be reference types

The above describes the declaration of PHP kernel Zend in the parameters summary, including the aspects of the content, I hope that the PHP tutorial interested in a friend helpful.
