For more information about how to use = in php and how to use it in php

When it is relatively simple type (such as String int float bool), it determines "equal & same type"

$ Num1 = 123; $ num2 = 123; $ num3 = '000000'; var_dump ($ num1 = $ num2); // output bool (true) var_dump ($ num3 ===$ num1); // output bool (false) because $ num3 is a string $ num1 is an integer

When comparing objects, you can determine whether to point to the same object"

Class Person {public $ name;} $ p1 = new Person (); $ p1-> name = 123; $ p2 = new Person (); $ p2-> name = 123; var_dump ($ p1 ===$ p2); // output bool (false). These two objects, although both of them are of the Person type and have the same value as var_dump ($ p1 = $ p2 ); // output bool (true). The values of the two objects are the same.
