Did you check operator precedence for versus ?
Perhaps you just need parentheses...

Hello there.
I am working with some bitwise Operators for validating some variables.
Now i need to know if an certain bit is NOT set and an other bit IS set.
Example.
?php

const VALIDATE_CHECK2 = 2;
const VALIDATE_CHECK3 = 4;
const VALIDATE_ALL= 7;

Thank you very much.
This seems to work :).
cool. heres's a couple of funcs that might help you to understand bitwise
operations better:
?php
/* whether there is only 1 single bit set or not */
function single_bit_set(/*int*/ $i)

sorry - I have had a php5 CLI at hand for so long
I forgot that 'php -r' is not available in v4.
that said the 'php -a' option also works (although
I always find the interactive mode odd to work with)

Hey all,
Question about ternary operators. You can't really use functions INSIDE
ternary operators, right? They can only be tokens and operators?
So
$fabulous = true;
$fabulous ? echo I am fabulous!\n : echo I am a looser!\n;
Would not work?
And this:

Hello,
From php manual:
$a $b Shift leftShift the bits of $a $b steps to the left (each step
means multiply by two)
$a $b Shift rightShift the bits of $a $b steps to the right (each step
means divide by two)
So i ask what this output?
$a = 4;
$b = 3;
echo $a $b;
echo $a $b;

I tested; I don't want to waste peoples time. Rewriting the question:
this outputs:
c = 32
d = 0
The question is why?
First row is the bit's number and the second row is the bit's value:
#8 | #7 | #6 | #5 | #4 | #3 | #2 | #1
---
128 | 64 | 32 | 16 | 8 |
The second value is the number of spaces to shift, dint realize that.
Thanks for your time Chris.

Are the and operators identical in semantics to those
operators in C? In particular, do they handle sign extension in
the same manner?

Hi:
For compare strings you can use strcmp.
$st1 = hi;
$st2 = bye;
if (strcmp($st1, $st2)) {
echo are different;
}
else {
echo are equal;
}
The strcmp return 0 when the strings are equal. If the strings are diferent,
return the pos of the char where begin the diference.
