[PHP] first three characters

[Rahul Bhide]

Gurus,
    How do I extract the first n characters out of a word . I have this-

$Word = attention

I want -

$Word_3 = att
$Word_4 = atte
$Word_5 = atten
this is only extracting first three/four/five characters .

What is the right function to use here ??

thx in advance.
~Rahul
