Basics to arrays Welcome to the arrays tutorial.
Summary: We will be looking into what arrays are and how to make and use them.

An array is a list of data. Here's what an array would look like.
Code:

$array = array('This is number 0','this is number 1','this is number 2');
echo $array[0]; //will print This is number 0
echo $array[1];//will print this is number 1
echo $array[2];//will print this is number 2
?>

I'm hoping you've noticed that to call the first piece of data you use the variable name which is $array followed by [0] and for the next piece of data you would do the same accept this time you would replace [0] with [1].

There's a more advanced way to call out all the data from an array which is probably too advanced for this tutorial, but seeing the there might be some quick learners ill show it.

Code:

$array = array('value 0','value 1','value 2'); //the array
for($i=0; $i
echo $array[$i].'
';
}
?>

What this does is it checks how many pieces of data there are in the array and sets $i to 0, so untill $i is the same amount as the amount of data in the array it keeps looping.
