set imap pagination

[mark107]

Hi all,

I need your help. I am working on my code as I want to set the limit to 25 as I want to fetch 25 emails from gmail using imap.

 

When I try this:

 

<?php

ini_set('display_errors', 1);
ini_set('display_startup_errors', 1);
error_reporting(E_ALL);

// Load Composer's autoloader
require_once "Mail.php";
require_once "Mail/mime.php";
require_once('Mail/IMAPv2.php');

$username = 'myusername@gmail.com';
$password = 'mypassword';

$server = '{imap.gmail.com:993/imap/ssl/ssl}INBOX';
$inbox = imap_open($server, $username, $password);

$test = listMessages($inbox);

print_r($test);


function listMessages($inbox) {
    $page = 1;
    $per_page = 25;
    $sort = null;
    $limit = ($per_page * $page);
    $start = ($limit - $per_page) + 1;
    $start = ($start < 1) ? 1 : $start;
    $limit = (($limit - $start) != ($per_page-1)) ? ($start + ($per_page-1)) : $limit;
    $info = imap_check($inbox);
    $limit = ($info->Nmsgs < $limit) ? $info->Nmsgs : $limit;
    $msgs = '';
    $result = '';

    
     $perPage = 25;
     $start = $page == 1 ? 0 : $page * $perPage - ($perPage - 1);
     $order = 0;
     $by = SORTDATE;


     if (is_array($sort)) {
         $order = $this->sortBy['order'][$sort[0]];
         $by = $this->sortBy['by'][$sort[1]];
     }
     $sorted = imap_sort($inbox, $by, $order);

    $mails = array_chunk($sorted, $perPage);
    $mails = $mails[$page - 1];
    print_r($mails);

    return $return;
}

?>

 

It will fetch and display 77,500 emails which is too much so I need to reduce it.

How I can fetch 25 emails from gmail using imap when I connect to my gmail inbox?

Your code isn't that far off.  imap_sort gives you a list of message numbers after the sorting has been applied.  You have that list split into pages using array_chunk.  Take the page you want and fetch those messages.  The second parameter to imap_fetch_overview is how you specify the messages you want to fetch, and documented as:

Quote

A message sequence description. You can enumerate desired messages with the X,Y syntax, or retrieve all messages within an interval with the X:Y syntax

So to fetch arbitrary messages, specify them as a comma-separated list of message numbers.  To do that, you can just implode your page of numbers that you get from the array_chunk result.

There is a lot of stuff in your listMessages function that is not necessary and can be removed.  After cleaning up the function and adding the call to imap_fetch_overview, the function would look like:

function listMessages($inbox, int $page, int $perPage) : array{
    $sorted = imap_sort($inbox, SORTDATE, 1);
    $pageList = array_chunk($sorted, $perPage);
    $messagesToFetch = implode(',', $pageList[$page - 1]);

    $details = imap_fetch_overview($inbox, $messagesToFetch);

    return array_reverse($details);
}

You can then use it to fetch a page of messages and display the summary info.

$messages = listMessages($inbox, $page ?? 1, 25);
foreach ($messages as $item){
    $number = $item->msgno;
    $date = $item->date ?? 'Unknown';
    $subject = $item->subject ?? '';
    printf("[%d] %s - %s\r\n", $number, $date, $subject);
}
