logical operators

[quicknik]

hi,

according to the docs the following
should work:
$choice1 = "";
$choice2 = "dog";
$default = "other";
$val = $choice1 or $choice2 or $default;

But on my box an empty string is returned (php 4.2.3)
apart from $choice1 isn't empty.

any hints ?

bye,

Try this instead:

$val = $choice1 || $choice2 || $default;

instead of

$val = $choice1 or $choice2 or $default;

@:

allready tried it.
result is boolean are returned.
but this is not what i want.

Then what the heck DO you want returned?

[quicknik]

i want php to behave perl alike.
that means:

in case choice1 is empty choice2 should
be returned.

Further down the page I found this:

Then $val is "", since the expression is equivilent to
($val = $choice1) or $choice2 or $default;

To get $val to be "dog" use:
$val=$choice1 or $val=$choice2 or $val=$default;

which is equivilent to
($val=$choice1) or ($val=$choice2) or ($val=$default);

ok that is what i need.
i bit unhandy ..but it fits my needs...
so thank you 🙂

bye,
