変数を作成して結果を表示する方法は？

Question

私はPHPの初心者ですので、私の混乱を許してください。これは、私のような誰かが変更するための非常に複雑なクエリです。

下記のクエリを参照してください。現在、すべての結果は$ row ['Post']に表示されています。代わりに、私は次のようなことをしたいと思っています：

$ somerow = $ row ['some_row']; $ somerow2 = $ row ['some_row2'];

そして、上記で使用した$変数を使ってどこでも使用できます。

私は、下記の本を使用してみましたが、それはうまくいきませんでした：

if($rows == 0) 
{ 
print(""); 

} 
elseif($rows > 0) 
{ 
while($row = mysql_fetch_array($query)) 
{ 

$postid = htmlspecialchars($row['post_id']); 
$postname = htmlspecialchars($row['post_name']); 


print("$postname and the id is $postid"); 
} 

} 

どのように私はこれを達成することができますか？

全クエリ：

$userid = Drawn from db for user viewing; 

$sql = "SELECT concat( (select client_name from user_accounts where 
User_id = tv.User_id), ' commanded ' , title_1 ,' on ', CAST(other_date AS

あなたは、アレイ内の各行を保存し、後で使用したい行を選ぶことができます。

if($rows == 0) 
{ 
    print("I have no rows!"); 
} 
else 
{ 
    $allrows = array(); 
    while($row = mysql_fetch_array($query)) 
    { 
     $allrows[] = $row; 
    } 
    $row1 = $allrows[0]; 
    $row2 = $allrows[1]; 
    echo $row1['Post']; // Print out first row 
    echo $row2['Post']; // Print out second row 
    var_dump($allrows); // Print out all the rows and the structure of this array 
} 

あなたはどこでもそれらの変数を使用したい場合は、それらをグローバルにする必要がありますが、私はそのようなまたはそのことについては、一般的に何のためのもののためのグローバル変数を使用しないことをアドバイスします。
