Firstly, there's no such function as "compress". I'd assumed you'd meant
"implode" which is the counterpart of "explode".

<?php

$orig = array('foo', 'bar', 'baz');
print "Original:\n"; var_dump($orig);
$imploded = implode(':', $orig);
$serialized = serialize($orig);
print "Imploded is '$imploded'.\n";
print "Serialized is '$serialized'.\n";
$exploded = explode(':', $imploded);
$unserialized = unserialize($serialized);
print "Exploded:\n"; var_dump($exploded);
print "\nUnserialized:\n"; var_dump($unserialized);

print "\n\n----------------------\n\n";

$orig = array('foo'=>12, 'bar'=>24, 'baz'=>18);
print "Original:\n"; var_dump($orig);
$imploded = implode(':', $orig);
$serialized = serialize($orig);
print "Imploded is '$imploded'.\n";
print "Serialized is '$serialized'.\n";
$exploded = explode(':', $imploded);
$unserialized = unserialize($serialized);
print "Exploded:\n"; var_dump($exploded);
print "\nUnserialized:\n"; var_dump($unserialized);

?>
