一、php_ap2_register_hook函数注册ap_hook_post_config到php_apache_server_startup函数
void php_ap2_register_hook(apr_pool_t *p)
{
ap_hook_pre_config(php_pre_config, NULL, NULL, APR_HOOK_MIDDLE);
ap_hook_post_config(php_apache_server_startup, NULL, NULL, APR_HOOK_MIDDLE);

ap_hook_child_init(php_apache_child_init, NULL, NULL, APR_HOOK_MIDDLE);
}
二、php_apache_server_startup函数中调用apache2_sapi_module结构体变量中的startup函数
static int php_apache_server_startup(apr_pool_t *pconf, apr_pool_t *plog, apr_pool_t *ptemp, server_rec *s)
{
void *data = NULL;
const char *userdata_key = "apache2hook_post_config";
/* Apache will load, unload and then reload a DSO module. This
* prevents us from starting PHP until the second load. */
apr_pool_userdata_get(&data, userdata_key, s->process->pool);
if (data == NULL) {
/* We must use set() here and *not* setn(), otherwise the
* static string pointed to by userdata_key will be mapped
* to a different location when the DSO is reloaded and the
* pointers won't match, causing get() to return NULL when
* we expected it to return non-NULL. */
apr_pool_userdata_set((const void *)1, userdata_key, apr_pool_cleanup_null, s->process->pool);
return OK;
}
/* Set up our overridden path. */
if (apache2_php_ini_path_override) {
apache2_sapi_module.php_ini_path_override = apache2_php_ini_path_override;
}
#ifdef ZTS
tsrm_startup(1, 1, 0, NULL);
#endif
sapi_startup(&apache2_sapi_module);
apache2_sapi_module.startup(&apache2_sapi_module);
apr_pool_cleanup_register(pconf, NULL, php_apache_server_shutdown, apr_pool_cleanup_null);
php_apache_add_version(pconf);
return OK;
}
apache2_sapi_module结构体的声明如下
