  Tutorial: PHP Development An Overview of Arrays in PHP Tutorial

This is a brief introductory tutorial on how to use arrays in PHP.

Tutorial Details:

Arrays in PHP

The PHP Manual defines an array in PHP as an ordered map. Personally, I don't like this definition. I will define an array in PHP as a collection of variables, which I think is a little more descriptive. In most languages, atleast the ones I am familar with, the variables in this collection must all be of the same type. Not so in PHP! This is because of PHP's Type Juggling .

I'm not going to go into great detail about Type Juggling, but basically it means that you don't declare a variable as a certain type. The context in which the variable is used determines its type.

So, how do you assign values to arrays?
The exact same way as you would any other variable, except that you specify which element of the array you wish to work with. One important thing to note is that, by default, arrays start numbering their elements at zero. Check this out:
$array [ 0 ] = 3 ;
$array [ 1 ] = 6 ;
$array [ 2 ] = 2 ;
?>
