will OR , && work

[desithugg]

umm i want to check if the user visiting the page has 2 character
1 male/trans
1 female/trans
and only continue if the user owns one of those character
[code]<?php if ($char1 == "Male" && $char2 == "Female" OR $char1  == "Male" && $char2 == "Trans" OR $char1 == "Female" && $char2 == "Male" OR $char1 == "Female" && $char2 == "Trans" OR $char1 == "Trans" && $char2 == "Male" OR $char1 == "Trans" && $char2 == "Female" OR $char1 == "Trans" && $char2 == "Trans")
{
echo"You have a pair.";
}
?>[/code]

will this work?

[quote]i want to check if the user visiting the page has [b]2[/b] character ... and continue if the user owns [b]one[/b] of those character[/quote]

That's less than clear. Care to elaborate?

[hackerkts]

It should works.

you need extra braces i beleave

[code]<?php if (($char1 == "Male" && $char2 == "Female") OR ($char1  == "Male" && $char2 == "Trans") OR ($char1 == "Female" && $char2 == "Male") OR ($char1 == "Female" && $char2 == "Trans") OR ($char1 == "Trans" && $char2 == "Male") OR ($char1 == "Trans" && $char2 == "Female") OR ($char1 == "Trans" && $char2 == "Trans"))
{
echo"You have a pair.";
}
?>[/code]

AndyB I think that he has some kinda game script or sumet and he wants to check if they have 2 diffrent variables selected which means they make up a pair..

lol sorry if i wasnt clear enough i just wanted to make sure that "OR" works in php not only querys.But it does work thanx

[shocker-z]

|| also works as an OR

[ignace]

OR is the same as ||, AND is the same as &&, bitwise or (|) bitwise and (&)

P.S.: can someone tell me what the & does when used in one of the following ways:

$Var &= $Var2; // object or something?
function myfunction(&$var); // Here, i believe you need to provide an already declared variable

if you know also otherways the & can be used, please let me know..

[king arthur]

When used thus: "myfunction(&$var);" you are passing a reference to the variable, not a copy of it.  Which means that if the function alters the value, the original variable gets altered and stays altered after the function returns, rather than a copy of the variable being altered and then thrown away when the function returns.

I guess "$var &= $var2" would logically and the values and stored the result in $var, so if they were 195 (binary 11000011) and 144 (binary 10001000) the result would be 128 (binary 10000000) but I've never used it in PHP (and seldom in C).

Sample "bitwise and"

[code]<?php
$var1 = 7;
$var2 = 3;

echo '<pre>';
printf ('%08s<br>%08s', decbin($var1), decbin($var2) );
echo '</pre>';

$var1 &= $var2;

echo "7 &amp; 3 = $var1";
?>[/code]

[ignace]

@Barand echo "7 &amp; 3 = $var1"; // Gives 3 right?

[Barand]

Yes. If you run the snippet you get
[pre]00000111
00000011
7 & 3 = 3[/pre]

[king arthur]

Should do.

Once you get your head around this binary malarky you can say to people things like "I'll be with you in 3 or 4 minutes" and what they don't realize is that actually gives you seven minutes.....

[Barand]

Converstional language is very lax when it comes to logic. People often specify something like "The query should select two records, where the id is 1 and the id is 2"

[ignace]

yeah, the only problem is my native language is dutch, so i can not use the bitwise or, and it would look silly, when your suddenly start talking english ;D
