What exactly does

2018-05-29 13:54:51

return (empty($neededRole) || strcasecmp($role, 'admin') == 0 || strcasecmp($role, $neededRole) == 0);

What exactly does the || mean in this statement? Can someone put this in english for me.

I promise I've googled this but I guess I don't know what to google for because I can't find anything.

thanks:)

It is the OR logicial operator.

Googling symbols is always hard. Don't worry: || means or in the statement. Don't confuse it for Xor which is slightly different:

or or || is meant as A or B or A + B

xor is meant as A or B, not both

Logical operator

This is an OR operator. It is true if any of it's 'parameters' is true.
