无法从php中获取数据库中的类别ID

Question

我正在尝试从我的数据库获取类别ID，但我不能。 请帮我获取类别ID和类别图像。我也与我的数据库连接， 我还将此文件包含在我的此文件中，但仍然没有获得类别ID和类别图像。

    <?php

    $categories_query=mysql_query("select categories_id,categories_image,categories_name,categories_introduction_text  from categories where  parent_id=0");
    $no_of_row=mysql_num_rows($categories_query);
    $i=1;
    while($categories_row=mysql_fetch_array($categories_query))
    {
            $cat_id=$categories_row['categories_id'];
            $cat_image=$categories_row['categories_image'];
            $cat_name=$categories_row['categories_name'];
            $cat_into_text=$categories_row['categories_introduction_text'];
            $j=$i%2;
    }
    if($j==1)
        {
?>
