如果滿足條件，如何在函數內部運行函數

Question

請我一直在嘗試創建一個函數，該函數將查詢數據庫，從表中選擇，如果行數不等於6，則從表中選擇一行並重復（或重復）直到行數為等於6。我已經在StackOverflow中搜索了此函數，但是沒有找到任何結果。 如果您有與此類似的鏈接，請在此處發布，我會嘗試一下。

這是我的代碼：

//List All active adverts
function showActiveAdverts()
{

    $status = 1;
    //Build final queries.
    $query = mysql_query("SELECT * FROM table WHERE 
             status = '".mysql_real_escape_string($status)."' ORDER BY rand() LIMIT 6") or die(mysql_error());

    $count = mysql_num_rows($query);
    $row = mysql_fetch_assoc($query);

# My question here, check if the $count >= 1 && $count != 6, then do getDefaultBannner() and repeat it until it runs for 6 times.
    if($count >= 1){ 
        do{ 
            $list[] = $row['id']; 
        }while($row = mysql_fetch_assoc($query));
        return $list;
    }
    else{ return FALSE; }
    }

這是getDefaultBannner（）的代碼

function getDefaultBannner()
{
    $status = 6;
    $query = mysql_query("SELECT id FROM table WHERE status = '".mysql_real_escape_string($status)."' ") 
            or die(mysql_error());

    $count = mysql_num_rows($query);
    $row = mysql_fetch_assoc($query);


    if($count >= 1){ 
        do{ 
            $list[] = $row['id']; 
        }while($row = mysql_fetch_assoc($query));
        return $list;
    }
    else{ return FALSE; }
}

提前致謝！

您可以這樣重寫代碼

//List All active adverts

$query = mysql_query("SELECT * FROM table WHERE 
             status = '".mysql_real_escape_string($status)."' ORDER BY rand() LIMIT 6") or die(mysql_error());

$count = mysql_num_rows($query);

if($count >= 1 && $count != 6)
  $list = getDefaultBannner();
else
  $list = showActiveAdverts($query);

function showActiveAdverts($query)
{

    $status = 1;
    //Build final queries.

    $row = mysql_fetch_assoc($query);

    if($count >= 1){ 
        do{ 
            $list[] = $row['id']; 
        }while($row = mysql_fetch_assoc($query));
        return $list;
    }
    else{ return FALSE; }
    }
