tip: compilation errors that refer to functions named zif_*() relate to functions defined with zend_fe.
for example, zend_fe( "first_module", null) introduces a function first_module() to php and links it to the c function zif_first_module().

注意 you cannot use the predefined macros for the end marker, as these would try to refer to a function named "null"!
the macro zend_fe (short for'zend function entry') simply expands to a structure entry in zend_function_entry.

cname, ns, and ptr records will each contain a 'target' key giving the particular location in the dns namespace which they refer to.
refresh interval (seconds) secondary name servers should use when updating remote copies of this domain. retry:

the variables generated with the snippet above will always be of local scope, so they reside in the context in which the function has been called. to create new variables in the global scope, use the same method but refer to another symbol table:
if you need to optimize for speed and don' t care about optimal memory usage, you can omit the check for an existing variable with the same value and instead force insertion into the symbol table by using zend_hash_update():

resources are a special kind of data type in php. the term resources doesn't really refer to any special kind of data, but to an abstraction method for maintaining any kind of information. resources are kept in a special resource list within zend. each entry in the list has a correspondending type definition that denotes the kind of resource to which it refers. zend then internally manages all references to this resource. access to a resource is never possible directly - only via a provided api. as soon as all references to a specific resource are lost, a corresponding shutdown function is called.
for example, resources are used to store database links and file descriptors.
