介绍PHP的一些内部机制,包括变量存储、数组实现等,随后详细介绍如何编写PHP扩展

/* include standard header */ #include "php.h" /* declaration of functions to be exported */ ZEND_FUNCTION(first_module); /* compiled function list so Zend knows what's in this module */ zend_function_entry firstmod_functions[] = { ZEND_FE(first_module, NULL) {NULL, NULL, NULL} }; /* compiled module information */ zend_module_entry firstmod_module_entry = { STANDARD_MODULE_HEADER, "First Module", firstmod_functions, NULL, NULL, NULL, NULL, NULL, NO_VERSION_YET, STANDARD_MODULE_PROPERTIES }; /* implement standard "stub" routine to introduce ourselves to Zend */ #if COMPILE_DL_FIRST_MODULE ZEND_GET_MODULE(firstmod) #endif /* implement function that is meant to be made available to PHP */ ZEND_FUNCTION(first_module) { long parameter; if (zend_parse_parameters(ZEND_NUM_ARGS() TSRMLS_CC, "l", &parameter) == FAILURE) return; RETURN_LONG(parameter); }
