Re: Logical OR in assignment

I once saw the use of OR (|) in assignment. $x = $y | $z; Does this use bitwise OR? I'm trying to see if I could use the above expression in place of: $x = is_null($y) ? $z : $y;

yes, '|' is bitwise OR, but that is /not/ a ternary operator. it's not safe to just replace the ternary operation with the bitwise operation. for example, if $y=5 and $z=9, then:

$x=$y|$z;             -> $x=13

$x=is_null($y)?$z:$y; -> $x=5 Kae
