功能中的多个数组不使用php mysql显示在结果中

I need to print/show list of comments for articles using this PHP function:

function _is_comments_($id,$type){

    $db = mysqli_access::F("SELECT message FROM " . COMMENTS . " WHERE pid = ? AND type = ? AND approved = 1 ", $id, $type);

    foreach($db as $row){
      $commentdata['message'] = $row['message'];
    }
    return $commentdata;
}   

In action :

$comments_list = _is_comments_('125','article');
print_r($comments_list);

In result : Array ( [message] => this is a One comment )

But in MySQL database I have 18 comments for article id 125 and my result is false and show only One result!

how do fix This ?!

    Your issue is the assignment in the loop here:

    foreach($db as $row){
      $commentdata['message'] = $row['message'];
    }
    

    Even if you got multiple result $rows, each iteration would overwrite the same $commentdata['message'] key. Which is why you only get to see one entry when returned from the function.

    Instead you want to collect multiple entries. I would just drop the ['message'] key, and use an additive indexed array:

    foreach($db as $row){
      $commentdata[] = $row['message'];
    }
    

    This way your result array might contain:

     Array (
        [0] => this is a One comment
        [1] => this is a second comment
        [2] => third one
    )
