C - 如何在 PHP 扩展中实例化 PHP 类

Question

如何在 PHP 扩展中实例化 PHP 类！

这是我的代码：

zval *obj;
MAKE_STD_ZVAL(obj);
zend_class_entry *foo_ce;
if( zend_hash_find( EG(class_table), "foo", sizeof("foo"), (void **)&foo_ce ) == SUCCESS ){
printf("get foo successn");
object_init_ex(obj, foo_ce);    
} else {
printf("get class failedn");
}
printf("heren");

但是当它进入object_init_ex片段时，我得到了Segmentation fault！

GDB 信息如下所示：

Answer 1

我找到了另一种使用zend_lookup_class找到 php 类并实例化它的方法;

zend_class_entry **class_ce, *old_scope;
zval *retval_ptr;
zend_lookup_class( name, strlen(name), &class_ce TSRMLS_CC )；
object_init_ex(return_value, *class_ce);

那么return_value现在是一个对象！
