The following table describes the entries.
Entry Description
name Contains the module name (for example, “File
functions”, “Socket functions”, “Crypt”, etc.).This
name will show up in phpinfo(), in the section
“Additional Modules.”
functions Points to the Zend function block, discussed in the
preceding section.
module_startup_func This function is called once upon module initialization
and can be used to do one-time initialization steps
(such as initial memory allocation, etc.) To indicate a
failure during initialization, return FAILURE; otherwise,
SUCCESS.To mark this field as unused, use NULL.To
declare a function, use the macro ZEND_MINIT.
module_shutdown_func This function is called once upon module shutdown
and can be used to do one-time deinitialization steps
(such as memory deallocation).This is the counterpart
to module_startup_func().To indicate a failure during
deinitialization, return FAILURE; otherwise, SUCCESS.To
mark this field as unused, use NULL.To declare a
function, use the macro ZEND_MSHUTDOWN.
request_startup_func This function is called once upon every page request
and can be used to do one-time initialization steps that
are required to process a request.To indicate a failure
here, return FAILURE; otherwise, SUCCESS.
Note: As dynamic loadable modules are loaded only on
page requests, the request startup function is called right
after the module startup function (both initialization
events happen at the same time).To mark this field as
unused, use NULL.To declare a function, use the macro
ZEND_RINIT.
request_shutdown_func This function is called once after every page request and
works as counterpart to request_startup_func().To
indicate a failure here, return FAILURE; otherwise,
SUCCESS.
Note: As dynamic loadable modules are loaded only on
page requests, the request shutdown function is
immediately followed by a call to the module shutdown
handler (both deinitialization events happen at the same
time).To mark this field as unused, use NULL.To declare
a function, use the macro ZEND_RSHUTDOWN.
