How to reduce the number of pages in pagination

Question

The code below is the function for pagination in my wordpress blog. Presently it outputs 7 pages and then the .. last page number.

How can I reduce this number so it shows only 5 pages and then ... last page number?

function emm_paginate_loop($start, $max, $page = 0) {
    $output = "";
    for ($i = $start; $i <= $max; $i++) {
        $output .= ($page === intval($i)) 
            ? "<span class='emm-page emm-current'>$i</span>" 
            : "<a href='" . get_pagenum_link($i) . "' class='emm-page'>$i</a>";
    }
    return $output;
}

Answer 1

I believe you're using 2 custom functions one of them is emm_paginate_loop() you're showing. But i saw that settings for that custom pagination is on function emm_paginate() and specifically "gap":

'gap' - Default is 3 (int). The minimum number of pages before a gap is replaced with ellipses (...).

But that only sets a minimum number...

I think you'd be better off using a plugin for this. WP-Paginate gives you this option along with other options that might be useful

Edit
Since a plugin isn't advisable for a mobile site, maybe you could add $range = 5 to the function

function emm_paginate_loop($start, $max, $page = 0, $range = 5) {
    $output = "";
    for ($i = $start; $i <= $max; $i++) {
        $output .= ($page === intval($i)) 
            ? "<span class='emm-page emm-current'>$i</span>" 
            : "<a href='" . get_pagenum_link($i) . "' class='emm-page'>$i</a>";
    }
    return $output;
}
