Example on how to read an entry from a ZIP archive (file "bar.txt" inside "./foo.zip"):

<?php

$fp = fopen('zip://./foo.zip#bar.txt', 'r');
if( $fp ){
    while( !feof($fp) ){
        echo fread($fp, 8192);
    }
    fclose($fp);
}

?>

Also, apparently, the "zip:" wrapper does not allow writing as of PHP/5.3.6. You can read http://php.net/ziparchive-getstream for further reference since the underlying code is probably the same.
