Summary

Array Tutorial:

Arrays are like strings except that they can hold multiple values, like for instance an online shopping cart may be one array of multiple items.

An empty array (to populate later) is established like this:


<?php
$my_array_name = array();
?>

Or you can establish it with values immediately:


<?php
$my_array_name = array('apples', 'oranges', 'pears', 'bananas', 'grapes');
?>

The above array's values can be accessed (for changing or reading values) seperately like so:


<?php
\$my_array_name[0]  // This value is "apples"
\$my_array_name[1]  // This value is "oranges"
\$my_array_name[2]  // This value is "pears"
\$my_array_name[3]  // This value is "bananas"
\$my_array_name[4]  // This value is "grapes"
?>


<html>
<body>


<?php

phpinfo();

$my_array_name = array('apples', 'oranges', 'pears', 'bananas', 'grapes');

 ?>

</body>
</html>

Tada
