zipping a folder's content php, not a whole folder - php

Question

I'm looking for a solution to zip a folder's content, including all subfolders that are in the folder, but not the main folder itself.
I started from this function, that adds a whole folder to a zip archive
function addFolderToZip($dir, $zipArchive){
if (is_dir($dir)) {
if ($dh = opendir($dir)) {
//Add the directory
$zipArchive->addEmptyDir($dir);
// Loop through all the files
while (($file = readdir($dh)) !== false) {
//If it's a folder, run the function again!
if(!is_file($dir . $file)){
// Skip parent and root directories
if( ($file !== ".") && ($file !== "..")){
addFolderToZip($dir . $file . "/", $zipArchive);
}
}else{
// Add the files
$zipArchive->addFile($dir . $file);
}
}
}
}
}
but I don't see how to change the function to (maybe using a third argument ?)
$z = new ZipArchive();
$z->open("zips/new.zip", ZIPARCHIVE::CREATE);
addFolderToZip("unzipped/",$z);
$z->close();

I've got it, I have created an argument $localpath, set to "":
function add_folder_in_path($folder_path,$local_path,$z)
{
$dh=opendir($folder_path);
while (($file = readdir($dh)) !== false)
{
if( ($file !== ".") && ($file !== ".."))
{
if (is_file($folder_path.$file))
{
$z->addFile($folder_path.$file,$local_path.$file);
}
else
{
add_folder_in_path($folder_path.$file."/",$local_path.$file."/",$z);
}
}
}
}
Here is how I call it
$z = new ZipArchive();
$z->open("zipped/new.zip", ZIPARCHIVE::CREATE);
echo "<br>";
add_folder_in_path("myzips/","",$z);
$z->close();
