<?php
// Create a data structure in memory:
$orig = array(
    array('name' => 'Dierdre', 'category' => 5),
    array('name' => 'Cheryl', 'category' => 3, 'spouse' => 'Bob'),
    array('name' => 'Fergus', 'category' => 3, 'spouse' => 'Glynis'),
    array('name' => 'Jonathas', 'category' => 2, 'spouse' => 'Amalia'),
    array('name' => 'SCA', 'type' => 'group', 'year' => 34)
    );

// Write it to a file, serialized, using locking to avoid conflicts
file_put_contents('output.ize', serialize($orig), LOCK_EX);

// Now read it all back in and unserialize it at the same time:
$new = unserialize(file_get_contents('output.ize'));

// Echo out the first entry's name ('Dierdre')
echo "First entry is: {$new[0]['name']}<br />";

// Now just go ahead and dump the entire structure to the screen:
echo '<pre>';
var_dump($new);
echo '</pre>';
