[RESOLVED] Hex my PHP?!

Copy linkTweet thisAlerts:

Heya folks, Im trying to build a stream of Hex values for a socket.

This works fine for example..

[CODE]$packet1 = “x32”;[/CODE]

If you echo $packet1 you would get “2”.

But now the following…

[CODE]$packet2 = ‘x32’;[/CODE]

Note the use of single quotes insted of double.

Now if you echo $packet2 you get “x32”, how would I go about typecasting $packet2 to be like $packet1?

Ok, let me explain more then *sigh*

Lets say for example I have the following code

[CODE]
$in = "x32x2ex33x2ex30x00x00x00x00x00x00x00x00x00x00x00";
$in .= GenKey(64);

function GenKey($length)
{
$key = "";
$table = "0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz";
for ( $count=0; $count<$length; $count++ )
{
$num = rand(0, 61);
$key .= sprintf("x%02x",ord($table[$num]));
}
return $key;
}
[/CODE]

This code outputs the first 16 values stored using double quotes correctly, but the remaining values returned by GetKey are stored in plain text, not as hex.
