Mutipul operaters in if statments.

xconspirisist

I'm almost positive that its possible without using two if statments...

psudo code:

if variable is equal to 'foo' or 'bar'

I've tried :

if ($var == 'foo' || 'bar')

and the same goes for this;

psude code:

if variable is true, and another_variable is true

I've tried

if ($var_1 == 'foo' AND $var_2 == 'bar')

but I cant get it to work for the life of me... Is there a way to avoid using hidiously messy double if's;

if ($foo == 'bar') { if ($bar == 'foo') {

Any help would be massivly appreciatve...

Did you know too, the textbox while posting in firefox is only about 30 columns wide, or so? It looks hideous, makes posting longer messages quite problematic.

// if variable is equal to 'foo' or 'bar'
if ($var == 'foo' || $var == 'bar') {...}

// if variable is true, and another_variable is true
if ($var_1 && $var_2) {...}

if ($var1 == 'bar' || $var1 == 'foo')
{
    echo 'it is one of them';
}

if ($var1 == true && $var2 == true)
{
   echo 'oh yes, they are both true';
}

First one is your OR, second is your AND

I dont know if I'm doing something so blindingly obvious here, but I certainly cant see the problem myself...

<?php

$foo == 1;
$bar == 1;

if ($foo == 1 && $bar == 1) {
	echo "meah.";
}
?>

<?php

$foo == 1;
$bar == 1;

if ($foo == 1 || $bar == 1) {
	echo "meah.";
}
?>

Change to

<?php

$foo = 1;
$bar = 1;

if ($foo == 1 || $bar == 1) {
    echo "meah.";
}
?>

== is for equivalence testing, = is for assignment, bizarrely you've just reversed the most common error in coding history - Rah! I like that.

Ahaha!!! My god, I must of looked at the code at least a million times, and assigned variables proberly about a trillion times. Only god knows why on earth I used a '==' this time, 😃 😃.

Many thanks, cwor, I really must get to bed, i'll be putting line terminators for full stops before long...

Once again, thanks so very much;

No probs, dude. I get it all the time, and call it going Code Blind, like Snow Blindness - you look at something so much it becomes meaningless, so you don't know if it's right / wrong or what - of course the second you give up and go to bed, then second you shut the light off you're screaming "OH MY GOD, WHAT WAS I THINKING!" and know exactly what's wrong.

Keep a laptop and wireless card next to the bed and you're fine.
