The difference between OR and || AND and && in php

$p = 6 or 0;
var_dump($p);//int(6)
$p = 6 || 0;
var_dump ($p);//bool(true)
$p = 6 and 0;
var_dump($p); //int(6)

var_dump($p); //bool(false)

Because the assignment operation has a higher priority than AND and OR, so first Assignment; is lower than && and ||, so logical operators are executed first, logical operations first, and then assignment.
