Question

我有两个表，第一个是tbl_blogs，其中包含所有博客类别，例如，男人，女人等。

第二个表包含博客的相关类别信息。

 $query1=mysqli_query($link,"select * from tbl_blog_cat");
    $array1=array();
    $array2=array();
    $rows=array();
    $row=array();
    if(mysqli_affected_rows($link)){
    while($row=mysqli_fetch_array($query1)){

        $catId=$row['id'];
        $catName=$row['title'];

        $q2=mysqli_query($link,"select * from tbl_blogs where 
           blog_cat=$catId");
        if(mysqli_affected_rows($link)){

            while($row2=mysqli_fetch_array($q2)){

                    $rows['BlogId']=$row2['BlogId'];
                    $rows['Title']=$row2['Title'];
                    $rows['blog_cat']=$row2['blog_cat'];

                   $rows['Description']=$row2['Description'];

                  $rows['CoverImage']=$row2['CoverImage'];
                    array_push($array1,$rows);

            }

            $array2[$catName]=$array1;

        }


    }
    echo json_encode($array2);
     }

-----------------这是我的输出-------------------

第二组女性类别具有与上一类别相同的ID。我希望将其删除，否则它会让我知道我的代码中是否有任何错误。

谢谢。enter code here

  { "Men": [ { "BlogId": "25", "Title": "layer", "blog_cat": "5", "Description": "a sheet, quantity, or thickness of material, typically one of several, covering a surface or body", "CoverImage": "Screenshot_from_2018-12-28_23-12-51.png" } ], "Women": [ { "BlogId": "25", "Title": "layer", "blog_cat": "5", "Description": "a sheet, quantity, or thickness of material, typically one of several, covering a surface or body", "CoverImage": "Screenshot_from_2018-12-28_23-12-51.png" }, { "BlogId": "19", "Title": "Blog Test Man", "blog_cat": "6", "Description": "no dsc", "CoverImage": "Screenshot_from_2019-01-07_16-54-44.png" }, { "BlogId": "22", "Title": "layer", "blog_cat": "6", "Description": "a sheet, quantity, or thickness of material, typically one of several, covering a surface or body", "CoverImage": "Screenshot_from_2018-12-28_23-12-51.png" }, { "BlogId": "24", "Title": "Blog Test Man", "blog_cat": "6", "Description": "no dsc", "CoverImage": "Screenshot_from_2019-01-07_16-54-44.png" } ] }

Answer 1

您一直在填充$array1，但是在开始新类别时并没有清除它。

尝试将$array1=array();放在第一个while之后

阵列中的博客名称重复
