1This file describes extension module API details. Refer to 2README.EXT_SKEL to create extension skeleton files. Refer to 3Hacker's Guide for PHP internals. 4 5http://www.php.net/manual/en/internals2.php 6 7 8 9Between PHP 4.0.6 and 4.1.0, the Zend module struct changed in a way 10that broke both source and binary compatibility. If you are 11maintaining a third party extension, here's how to update it: 12 13If this was your old module entry: 14 15zend_module_entry foo_module_entry = { 16 "foo", /* extension name */ 17 foo_functions, /* extension function list */ 18 NULL, /* extension-wide startup function */ 19 NULL, /* extension-wide shutdown function */ 20 PHP_RINIT(foo), /* per-request startup function */ 21 PHP_RSHUTDOWN(foo), /* per-request shutdown function */ 22 PHP_MINFO(foo), /* information function */ 23 STANDARD_MODULE_PROPERTIES 24}; 25 26Here's how it should look if you want your code to build with PHP 274.1.0 and up: 28 29zend_module_entry foo_module_entry = { 30#if ZEND_MODULE_API_NO >= 20010901 31 STANDARD_MODULE_HEADER, 32#endif 33 "foo", /* extension name */ 34 foo_functions, /* extension function list */ 35 NULL, /* extension-wide startup function */ 36 NULL, /* extension-wide shutdown function */ 37 PHP_RINIT(foo), /* per-request startup function */ 38 PHP_RSHUTDOWN(foo), /* per-request shutdown function */ 39 PHP_MINFO(foo), /* information function */ 40#if ZEND_MODULE_API_NO >= 20010901 41 PHP_FOO_VERSION, /* extension version number (string) */ 42#endif 43 STANDARD_MODULE_PROPERTIES 44}; 45 46If you don't care about source compatibility with earlier PHP releases 47than 4.1.0, you can drop the #if/#endif lines. 48
