变量的php分页包含数组

Question

i want to display 2 array record per pages.Please help with the simple pagination.when user clicks on next page next 2 array record should display.

[dotdList] => Array
        (
[0] => Array
                (
                    [title] => Just at Rs. 799
                    [description] => Ambrane
                 )
[1] => Array
                (
                    [title] => Flat Rs.249
                    [description] => Sarees & more
                )

[2] => Array
                (
                    [title] =>  Extra 10% off
                    [description] => Routers
                )
[3] => Array
                (
                    [title] => Just Rs.549
                    [description] => From Nova
                )
)

This is what i have tried and the array contains around 1500 Records.Pagination is not looking good. Its giving very big result and if i wanna hide some of the numbers in between just to reduce its width. or may be next option or dot in between. I wanna display minimum of 15-20 records per pages.

Answer 1

Let me explain you logic:

1) Take count of array into a variable.

2) Count number of page from above variable.

3) Show pagination href links below the records.

4) If the page number is invalid, show page not found error.

<?php
$arr = array(
  array('title' => 'Just at Rs. 799', 'description' => 'Ambrane'), 
  array('title' => 'Flat Rs.249', 'description' => 'Sarees & more'), 
  array('title' => ' Extra 10% off', 'description' => 'Routers'), 
  array('title' => 'Just Rs.549', 'description' => 'From Nova')
);
// display
$page = isset($_REQUEST['page']) && $_REQUEST['page'] > 0 ? $_REQUEST['page'] : 1;
function display($arr, $page = 1) {
    $start = ($page - 1) * 2;
    $arr = array_slice($arr, $start, 2);
    foreach ($arr as $key => $val) {
        echo $val['title'] . '<br/>';
        echo $val['description'] . '<br/>';
        echo "<br>";
    }
}
$len = count($arr);
$pages = ceil($len / 2);
if ($page > $pages or $page < 1) {
    echo 'page not found';
}
else {
    display($arr, $page);
    for ($i = 1 ; $i <= $pages ; $i++) {
        $current = ($i == $page) ? TRUE : FALSE;
        if ($current) {
            echo '<b>' . $i . '</b>';
        }
        else {
            ?>
<a href="?page=<?php echo $i;?>"><?php echo $i;?></a>
<?php
        }
    }
}
