The following is a detailed summary of the differences between or and | AND & amp; in php. if you need a friend, you can refer to the differences, however, sometimes the operator priority issue is involved, and the results are different and recorded.
For example:

The code is as follows:

$ P = 6 or 0;
Var_dump ($ p); // int (6)

$ P = 6 | 0;
Var_dump ($ p); // bool (true)

$ P = 6 and 0;
Var_dump ($ p); // int (6)

$ P = 6 & 0;
Var_dump ($ p); // bool (false)

Because the value assignment has a higher priority than and or, the value is assigned first. The value assignment is lower than the value & |. Therefore, the logical operators are executed first, the logical operations are performed first, AND then the values are assigned.
