Both are *logical* Operators.
The differenz is the priority of them.
|| ist higher than OR. (froam high to low: &&, ||, and, or)
So if you have $a or $b || $c
you must read it like that $a or ($b || $c)

Interesting, when you mix AND, OR, &&, ||

So:
$a or $b && $c is not the same as $a || $bc and $c
