Getting first letter or number from variable

[hlstriker]

Hi, I was wondering how I could get the first letter or number from a variable. I thought maybe with $var[0] but that didn't seem to work for me.

 

EDIT: Nevermind was a different error in my code, BUT how can I make this letter turn lowercase even if its capital?

That should have worked. You can also do

<?php
$str = 'This is a test';
$first_letter = substr($str,0,1);
?>

Thanks alot Ken, it was just a different error in my code. I edited my first post because I had another question to go along with this.

Use strtolower()

you can also do:

<?php
        $str = 'This is a test';
        $first_letter = $str[0];
?>
