The method name and class name are consistent. The default is the constructor. Is it 5.3 or 7.1 or later?

Question

Which version does this writing method apply to?

Answer 1

Before version 5, the constructor did not have an independent name. The function whose method name was the class name was the constructor of the current class. After version 5, __construct was introduced as the constructor of the class, and the same applies to version 7.
