    I found some code that works! this will download any attachments to a selected folder

    <?php 
    
    $gmail_username = 'username@gmail.com';
    $gmail_password = 'mypassword';
    
    $imap = imap_open ("{imap.gmail.com:993/imap/ssl}INBOX", $gmail_username, $gmail_password) or die("can't connect: " . imap_last_error());
    $savefilepath = 'path/to/images_folder/'; //absolute path to images directory
    $imagefilepath = 'images/'; //relative path to images directory
    
    $headers = imap_headers($imap);
    foreach ($headers as $mail) {
        $flags = substr($mail, 0, 4);
        //Check for unread msgs, get their UID, and queue them up
        if (strpos($flags, "U")) {
            preg_match('/[0-9]+/',$mail,$match);
            $new_msg[] = implode('',$match);     
        }
    }
    
    if ($new_msg) {
        foreach ($new_msg as $result) {
            $structure = imap_fetchstructure($imap,$result);
            $parts = $structure->parts;
            foreach ($parts as $part) {
                if ($part->parameters[0]->attribute == "NAME") {
                    //Generate a filename with format DATE_RANDOM#_ATTACHMENTNAME.EXT
                    $savefilename = date("m-d-Y") . '_' . mt_rand(rand(), 6) . '_' . $part->parameters[0]->value;
                    save_attachment(imap_fetchbody($imap,$result,2),$savefilename,$savefilepath,$savethumbpath);
                    imap_fetchbody($imap,$result,2); //This marks message as read
                } 
            }
        }
    }
    
    imap_close($imap);
    
    function save_attachment( $content , $filename , $localfilepath, $thumbfilepath ) {
        if (imap_base64($content) != FALSE) {   
            $file = fopen($localfilepath.$filename, 'w');
            fwrite($file, imap_base64($content));
            fclose($file);
        }
    }
    ?>

    The php docs for imap_open explain connecting to gmail in the comments (e.g. 31-Oct-2007 07:50):

    $mbox = imap_open("{imap.gmail.com:993/imap/ssl}INBOX", "username@gmail.com", "password") or die("can't connect: " . imap_last_error());

    Where, obviously, you have to fill in the actual username and password as appropriate, and then to identify the attachments in the parts of the email you follow the instructions from: http://www.electrictoolbox.com/extract-attachments-email-php-imap/

    Which, summarizing, says that you use:

    // in a for($i=1;$i<$nummsgs;$i++) loop over all the messages in the inbox $structure = imap_fetchstructure($mbox, $i);

    to identify the attachments in the structure. However, that is a rather elaborate process of deconstructing MIME messages (which have a lot of optional variability that must be accounted for), so the fundamentals/outline of a function for that is in that electrictoolbox page.

    I recently worked on this topic and here is the code which works well. It also saves the details of the attachments in a word document with the following details:
    -> Date
    -> Time
    -> From
    -> Email ID
    -> Subject
    
    
    
    
    
    
    
    
    
    
    <?php 
    
    
     /*
        *   Gmail attachment extractor.
        *
        *   Downloads attachments from Gmail and saves it to a file.
        *   Uses PHP IMAP extension, so make sure it is enabled in your php.ini,
        *   extension=php_imap.dll

        header('Content-type:application\msword');
        header('Content-Disposition:attachment;Filename=document_name.doc');

        $hostname = '{imap.googlemail.com:993/imap/ssl}INBOX';
        $username = 'email@gmail.com';
        $password = 'password';
        /* try to connect */
        $inbox = imap_open($hostname,$username,$password) or die('Cannot connect to

    You will have to enable IMAP access to your GMail account (Settings → Forwarding and POP/IMAP), and then use imaplib.IMAP4_SSL to access it.

    Use the raw text of every message as an argument to email.message_from_string in order to process any attachments.

    I took the code above and fixed it and tested it. It works with PHP5.

    <?php 
    
    $gmail_username = 'email@gmail.com';
    $gmail_password = 'password';
    $imap = imap_open ("{imap.gmail.com:993/imap/ssl}INBOX", $gmail_username, $gmail_password) or die("can't connect: " . imap_last_error());
    $savefilepath = '//Server/share/Local/Pathname/'; //absolute path to images directory
    $imagefilepath = '/Local/Pathname/'; //relative path to images directory
    $savethumbpath = '/Local/Pathname/'; //relative path to images directory
    $headers = imap_headers($imap);
    foreach ($headers as $mail) {
        $flags = substr($mail, 0, 4);
        //Check for unread msgs, get their UID, and queue them up
        if (strpos($flags, "U")) {
            preg_match('/[0-9]+/',$mail,$match);
            $new_msg[] = implode('',$match);     
        }
    }
    if ($new_msg) {
        foreach ($new_msg as $result) {
            $structure = imap_fetchstructure($imap,$result);
            $parts = $structure->parts;
            foreach ($parts as $part) {
                if ($part->parameters[0]->attribute == "NAME") {
                    //Generate a filename with format DATE_RANDOM#_ATTACHMENTNAME.EXT
                    $savefilename = date("m-d-Y") . '_' . rand() . '_' . $part->parameters[0]->value;
                       save_attachment(imap_fetchbody($imap,$result,2),$savefilename,$savefilepath,$savethumbpath);
                    imap_fetchbody($imap,$result,2); //This marks message as read
                } 
            }
        }
    }
    /* grab emails */
    $emails = imap_search($imap,'ALL');
    /* if emails are returned, cycle through each... */
    if($emails) {
      /* put the newest emails on top */
      $total = imap_num_msg($imap);
      /* for every email... */
      for( $i = $total; $i >= 1; $i--) {
            $headers = imap_header($imap, $i);
            $from = $headers->from[0]->mailbox . "@" . $headers->from[0]->host;
            echo $from . "\n";
            imap_delete($imap,$i);
            imap_mail_move($imap,"$i:$i", "[Gmail]/Trash"); // Change or remove this line if you are not connecting to gmail. The path to the Trash folder in your Gmail may be different, capitalization is relevant.
      }
    }else{
            echo "no emails";
    }
    /* close the connection */
       imap_expunge($imap);
       imap_close($imap);
    
    function save_attachment( $content , $filename , $localfilepath, $thumbfilepath ) {
         if (imap_base64($content) != FALSE) {   
             $file = fopen($localfilepath.$filename, 'w');
             fwrite($file, imap_base64($content));
             fclose($file);
         }
    }
    ?>
