Search through multiple directories for files PHP - php

Question

New to php. I need to search through multiple directories on an ftp server and download files contained in them according to their date (which is contained in each file's name). So far I am running into issues with Array to string conversion - hopefully you can see what I am "trying" to do here and might be able to help me out.
<?php
$url = ' MY FTP SERVER';
$user = ' USERNAME ';
$pass = ' PASSWORD';
$target = 'LOCAL DIRECTORY';
$connection = ftp_connect($url) or die ("Could not connect to $url");
$loginBool = ftp_login($connection, $user, $pass);
if ($loginBool)
{
echo "Connected as $user at $url";
}else{
echo "Could not connect as $user";
}
ftp_chdir($connection, 'MOVE ONE FOLDER IN');
$ftpDirectories = ftp_nlist($connection, ".");
for($i=0; $i < (count($ftpDirectories)); $i++){
$directory = ("/MAIN DIR/$ftpDirectories[$i]/");
echo $directory;
ftp_chdir($connection, $directory);
echo ftp_nlist($connection, $directory);
}
?>
The logic, as I see it, works as follow:
Get a listing of all folders under the main folder which is stored in Array
Loop through each element of the array(folders on the ftp)and change into the directory
one by one
Print out the files (so I know its working)
What I still need to add:
After changing into a directory split the filenames into an array and compare them to
today's date -> download if the filenameDate[index] == today's date
THANK YOU FOR YOUR HELP!
EDIT
<?php
$url = 'pmike86.zxq.net';
$user = 'pmike86_zxq';
$pass = '******';
$target = 'C:\Folder\\';
$connection = ftp_connect($url) or die ("Could not connect to $url");
$loginBool = ftp_login($connection, $user, $pass);
if ($loginBool)
{
echo "Connected as $user at $url";
}else{
echo "Could not connect as $user";
}
ftp_chdir($connection, 'HW');
$ftpDirectories = ftp_nlist($connection, ".");
for($i=0; $i < (count($ftpDirectories)); $i++){
$directory = ("/HW/$ftpDirectories[$i]/");
echo $directory;
ftp_chdir($connection, $directory);
foreach (ftp_nlist($connection, $directory) as $item)
{
ftp_get($connection, $target, $item, FTP_BINARY);
}
}
?>
