sick of isset and !isset
I am sick of isset screwing me,......anyone else go through this before?

PHP Code:
if( ( !isset( $_COOKIE['uid'] ) ) && ( !isset( $_COOKIE['phash'] ) ) )
{
     /*
     This will make the if statement return false and die().
     even if the cookies not set
     */
}
else
{
    die( "Cookies Not Set, Please Login" );
} 


PHP Code:
if( ( $_COOKIE['uid'] ) && ( $_COOKIE['phash'] ) )
{
     // This works fine
}
else
{
    die( "Cookies Not Set, Please Login" );
}

I really don't see the problem with this code:
Code:
if( ( !isset( $_COOKIE['uid'] ) ) && ( !isset( $_COOKIE['phash'] ) ) )
{
    print "Both Not Set";
}
else
{
    die( "Cookies Not Set, Please Login" );
}

Its prints "Both Not Set" when I run it.
Take a look at some of your code before these lines and make absolute sure you are not setting either one of these variables.
The best thing to do is what I did... Put this in a file by itself and run it.

ok now try it this way,...

PHP Code:
if( ( isset( $_COOKIE['uid'] ) ) && ( isset( $_COOKIE['phash'] ) ) )
{
    die( "cookies are set??? or,... isset() has failed me again" );
}
else
{
    die( "Cookies Not Set" );
} 


see what I mean?

In order for this line to be true:
PHP Code:
if( ( isset( $_COOKIE['uid'] ) ) && ( isset( $_COOKIE['phash'] ) ) ) 

Both $_COOKIE['uid'] and $_COOKIE['phash'] would have to have been set... this just is not the case, thus the statement returns false and the else part is executed.
