I don't know how you want to import these objects but here is an example:
<?php
// File 1
class SQL {
function SQL($host....) {
}
function Query($query) {
....
}
}
?>
<?php
// File 2
include("file1.php");
$SQLObj = new SQL($myhost, $myuser....);
$resultarray = $SQLObj->Query("SELECT blah blah");
?>
Is this what you meant by inclusion of objects?
