How can I call up the prompt function of zendstudio8?

Ask zendstudio8 how to call up the prompt function, such as classA, enter A, and then enter & quot ;. & quot; all the members of Class A are displayed. However, the zendstudio8 IDE does not know this function. If this function is not available, I would like to ask how to call the zend studio8 prompt function.
For example, vs has the automatic prompt function for class members, for example, class A. input A and then input "." the system prompts all the members of class. However, the zend studio8 IDE does not know this function. Without this function, writing code is too troublesome. who can remember all the members in the encapsulated class. Please help me!
