In php extension development, how to initialize an attribute in the class? The default value is an empty array.

The requirement is similar to the following php code: {code...} note that it is not initialized in the constructor ~ Let's take a look ...... If you use zend_declare_property to initialize an empty array, the following error is returned: Fatalerror: Internalzval & #039; scan & #039; tbearray... the requirement is similar to the following php code:

Class Foo {protected $ bar = [];}

Note that it is not initialized in the constructor ~

Let's take a look ...... If you use zend_declare_property to initialize an empty array with the property, the following error is returned:

Fatal error: Internal zval's can't be arrays, objects or resources in Unknown on line 0

Initialize the constructor or create handler. Is this a problem?

Class Foo {protected $ bar = array ();}
