[英]What is the correct way to push into an array that is a property of an object?
[英]What is the correct way to get the object instance inside its own method in zval format and update a property with a long value?
我正在為 c 中的 php 創建擴展,但在更新 long 類型的屬性時出錯。 我正在嘗試使用下面的代碼來更新屬性。
zend_update_property_long(kaya_class_entry, getThis(), "lastError", sizeof("lastError") - 1, error);
這是我在使用“getThis()”的任何地方都使用“getThis()”的方法的實現,它會引發錯誤。
PHP_METHOD (Kaya, login) {
KAYA *ptr = NULL;
zend_string * username;
zend_string * password;
ZEND_PARSE_PARAMETERS_START(2, 2)
Z_PARAM_STR(username)
Z_PARAM_STR(password)
ZEND_PARSE_PARAMETERS_END();
zend_resource *kaya;
zval kaya_ptr;
int error;
char *mUsername = ZSTR_VAL(username);
char *mPassword = ZSTR_VAL(password);
char *mLicenseDir = licenseDir();
ptr = fn_kaya_login(mLicenseDir, mUsername, mPassword, &error);
if (mLicenseDir != NULL) free(mLicenseDir);
zend_update_property_long(kaya_class_entry, getThis(), "lastError", sizeof("lastError") - 1, error);
if (ptr == NULL) RETURN_FALSE;
kaya = zend_register_resource((void *) ptr, le_kaya);
ZVAL_RES(&kaya_ptr, kaya);
zend_update_property(kaya_class_entry, getThis(), "resource", sizeof("resource") - 1, &kaya_ptr TSRMLS_CC);
RETURN_TRUE;
}
編譯時出現以下錯誤。

在 php 5 你可以這樣做
custom_object *obj = (custom_object *)zend_object_store_get_object(
getThis() TSRMLS_CC);
不幸的是,對於 php 7,我也堅持這一點,我做了大約 5-6 個小時的研究,他們為 php7 更改了很多命令和功能,所以我認為這變得不可能了。 如果可能的話,我真的很震驚這些東西的記錄有多糟糕,即使在 StackOverflow 上,這是 5 年來關於它的第一個話題。 甚至他們的官方“文檔”也不再是最新的。
解決此問題的一種可能方法是:
你可以投:
(zend_object *) Z_OBJ_P (getThis())
或者創建一個宏,使用演員表
#define GET_INSTANCE() (zend_object *) Z_OBJ_P (getThis())
並刪除“TSRMLS_CC”,TSRMLS_CC 是啟用 ZTS 時使用的宏
zend_object *object = GET_INSTANCE();
zend_update_property(kaya_class_entry, object, "resource", sizeof("resource") - 1, &kaya_ptr);
