调用php函数

1，创建新的扩展

./ext_skel --extname=fcall

2，代码

typedef struct _zend_fcall_info {
	size_t size;
	HashTable *function_table;
	zval *function_name;
	HashTable *symbol_table;
	zval **retval_ptr_ptr;
	zend_uint param_count;
	zval ***params;
	zval *object_ptr;
	zend_bool no_separation;
} zend_fcall_info;

typedef struct _zend_fcall_info_cache {
	zend_bool initialized;
	zend_function *function_handler;
	zend_class_entry *calling_scope;
	zend_class_entry *called_scope;
	zval *object_ptr;
} zend_fcall_info_cache;


zend_fcall_info finfo;
zend_fcall_info_cache fcache;
char *name = NULL;
zval **params[1];
zval *arg, *retval = NULL;

zend_fcall_info_init(&fname, IS_CALLABLE_STRICT, &finfo, &fcache, &name, NULL TSRMLS_CC); //初始化fcall_info

/*填充参数*/
MAKE_STD_ZVAL(arg);
ZVAL_STRING(arg, "Hello World", 1);
params[0] = &arg;


finfo.param_count = 1; //参数数量
finfo.params = params; //参数
finfo.retval_ptr_ptr = &retval; //返回值

/*执行函数*/
zend_call_function(&finfo, &fcache TSRMLS_CC)
