Variable Types question

[tony]

Does PHP have a byte or character type ?

If I do

$email = "to**@tony.com";
echo $email[0];

I can get the letter "t"

However according to the documentation (and my tests) this is not being
extracted as a character but a string.

How can I extract just the character itself ?

To test this you can do this:

echo ((int)$email[0]);
and it returns 0.
is there a character (byte) type at all ?

That is the letter itself. What, precisely are you trying to do?
To test this you can do this:

echo ((int)$email[0]);
and it returns 0.

In order to get the numerical value of a character, you need to use the
ord() fuction. <http://www.php.net/ord>
