php-fpm运行时，扩展里面MINIT,MSHUTDOWN,RINIT,RSHUTDOWN四个函数的执行过程

#define FILENAME "/tmp/test"

static void append_file(char *s) {
	FILE *fp = fopen(/tmp/test, "a");
	fputs(s, fp);
	fclose(fp);
}

/* {{{ PHP_MINIT_FUNCTION
 */
PHP_MINIT_FUNCTION(test)
{
    append_file("MODULE_INIT\n");
    /* If you have INI entries, uncomment these lines
    REGISTER_INI_ENTRIES();
    */
    return SUCCESS;
}
/* }}} */

/* {{{ PHP_MSHUTDOWN_FUNCTION
 */
PHP_MSHUTDOWN_FUNCTION(test)
{
    append_file("MODULE_SHUTDOWN\n");
    /* uncomment this line if you have INI entries
    UNREGISTER_INI_ENTRIES();
    */
    return SUCCESS;
}
/* }}} */

/* Remove if there's nothing to do at request start */
/* {{{ PHP_RINIT_FUNCTION
 */

{
    append_file("REQUEST_INIT\n");
#if defined(COMPILE_DL_FUCK) && defined(ZTS)

    return SUCCESS;
