分页在 php 中无法正常工作

Question

I am trying to make my pagination the way I want. Currently, it is working fine but all the numbers are displaying. Plus the total number is fixed. I want to implement pagination in a proper way. I want to make it dynamic. Mean it should count total pages from the last date that is available in the database. Code

        $joursParPage = 3;
        $joursTotales = '45';
        $pagesTotales = ceil($joursTotales/$joursParPage);
        if(isset($_GET['page']) AND !empty($_GET['page']) AND $_GET['page'] > 0 AND $_GET['page'] <= $pagesTotales) {
           $_GET['page'] = intval($_GET['page']);
           $pageCourante = $_GET['page'];
        } else {
           $pageCourante = 1;
        }
        $depart = ($pageCourante-1)*$joursParPage;



        for($i=$depart;$i<=$pageCourante*3;$i++) {
    ?>

        <h4 class="block-title">
            <span style="margin-right: 0px;">Actualités du <?php echo utf8_encode(strftime('%A %d %B %Y', strtotime('-'.$i.' day'))); ?></span>
        </h4>
        <?php 
        $date = strftime('%Y-%m-%d', strtotime('-'.$i.' day'));
        $videoDer = $bdd->prepare('SELECT * FROM videos WHERE date_video = ? ORDER BY id DESC');
        $videoDer->execute(array($date));
        while($vD = $videoDer->fetch()) { ?>

    <?php }
        $articleDer = $bdd->prepare('SELECT * FROM articles WHERE date_article = ? ORDER BY id DESC');
        $articleDer->execute(array($date));
    while($aD = $articleDer->fetch()) { ?>

    <?php } ?>
    <?php } ?>
    <div class="lien_page">
    <span class="page_titre"> Pages  </span>
 <?php
  for($l=1;$l<=$pagesTotales;$l++) {
     if($l == $pageCourante) {
        echo '<span class="pageActuelle">'.$l.'</span>';
     } else {
        echo ' <a href="index.php?page='.$l.'" class="lien_page">'.$l.'</a> ';
     }
  }
  ?>

Well you are doing in a heavy way

Best way is to use limit clause instead of for loop to access specific no of records like you are doing.

$recordsPerPage = 5;
$currentPage    = (isset($_GET['page]) && $_GET['page'] > 0)?$_GET['page]:1;
if($currentPage == 1){
    $startRecord = 1;
}else{
    $startRecords   = (($currentPage - 1) * $recordsPerPage) + 1 
    // it will be 6 in case of Page=2
    // it will be 11 in case of Page 3
}

$date           = strftime('%Y-%m-%d', strtotime('-'.$i.' day'));
$videoDer       = $bdd->prepare('SELECT * FROM videos WHERE date_video = ? ORDER BY id DESC limit '.$startRecords.', '.$recordsPerPage);
$videoDer->execute(array($date));


// your query looks like
select *
from videos
where date_video = ''
order by id desc
limit 6,5;
