函数只返回一个元素

标签： php mysql function return

为什么这个函数只返回一个，最后一个元素从数据库中输入？来自不同类别的更多内容：

函数从表“tentego_cat”获取类别id，在“tenteg_img”上搜索元素，其中“tentego_vote”表上的记录最多

功能代码：

function bestOfDay($pattern, $where, $currentPage, $objPerPage)
{
    global $ads, $user, $rewrite, $kernel, $page;
    if (!isset($_SESSION['last_cat'])) $_SESSION['last_cat'] = false;
    $plugins = $this->loadPlugins();
    $sett = $page;
    if (isset($currentPage) && is_numeric($currentPage) && $currentPage > 0) {
        $page = mysql_real_escape_string($currentPage - 1) * $objPerPage;
    }
    else $page = 0;
    $selectCategory = mysql_query("SELECT tentego_img_cat.* FROM tentego_img_cat");
    while ($cat = mysql_fetch_array($selectCategory)) {
        $catID = $cat['id'];
        $date = date('Y-m-d');
        $query = mysql_query("SELECT tentego_img.* FROM tentego_img INNER JOIN tentego_img_vote ON tentego_img.id = tentego_img_vote.object_id WHERE cat =$catID GROUP BY tentego_img_vote.object_id ORDER BY SUM( (CASE WHEN tentego_img_vote.vote = '0' AND tentego_img_vote.date LIKE '" . $date .

        $text = NULL;
        $return = NULL;
        while ($img = mysql_fetch_array($query)) {

为什么使用$return = NULL; ??

当您需要使用$return = '';

    if (isset($currentPage) && is_numeric($currentPage) && $currentPage > 0) {
        $page = mysql_real_escape_string($currentPage - 1) * $objPerPage;
    }
    else $page = 0;
