Php email attachment extraction - php

Question

I'm trying to create a piece of code that will go into the mailbox and take out the attachments of a specific file. So far I am only able to view if there is an attachment or if there is not an attachment on the e-mail.
But I want it to be able to take the attachments out of the e-mail and then save them to a specified directory. The type of attachment I'm trying to take out is a .jpg
I've tried a bunch of different pieces of code that I've found on google and I've been trying to tailor it to fit into my code, but so far I have been unsuccessful in finding anything that works correctly.
I was wondering if anyone would be able to help me create a piece of code that would be able to take the attachments out of the emails and store them in a directory.
Thanks.
<?php
/* connect to email */
$hostname = '{*****.com:110/pop3}INBOX';
$username = '*****';
$password = '*****';
// try to connect
$inbox = imap_open($hostname,$username,$password) or die('Cannot connect to server: ' . imap_last_error());
// grab emails
$emails = imap_search($inbox,'ALL');
// Search for the 39th email, which has an attachment
$count = 39;
// Fetch all the information about an email
$attachment = imap_fetchstructure($inbox, $count);
// find out how may parts the object has
$numparts = count($attachment->parts);
// find if if multipart message
if ($numparts >= 2) {
foreach ($attachment->parts as $part) {
if ($part->disposition == "INLINE") {
// inline message. Show number of lines
printf("Inline message has %s lines<BR>", $part->lines);
} elseif ($part->disposition == "ATTACHMENT") {
// an attachment
echo "Attachment found!";
// print out the file name
echo "Filename: ", $part->dparameters[0]->value;
}
}
}
//}
else {
// only one part so get some useful info
echo "No attachment";
}
imap_close($imap);
?>

Instead of imap_search I used imap_check to retrieve messages overview, and the following worked.
Go over messages found with imap_check, and this is how you extract the binary data of attachment:
$mbox = imap_open( . . . . );
$IMAPobj = imap_check($inbox);
$start = $IMAPobj->Nmsgs-30;
$end = $IMAPobj->Nmsgs;
$result = imap_fetch_overview($inbox,"$start:$end",0);
$count = $end;
foreach ($result as $overview) {
$parts = mail_mime_to_array($inbox, $count);
foreach($parts as $part) {
if(#$part['filename'] || #$part['name'] ) {
$partName = $part['filename'] ? $part['filename'] : $part['name'];
echo "Attachment name is " . basename($partName);
echo "\n";
if(preg_match( . . . write here a regex to detect ".jpg" in $partName . . .)) {
echo "Found file! Extracting binary data...";
$fileContents = $part['data'];
file_put_contents("attachment.jpg", $fileContents);
}
}
}
}
