PHP自動設置號碼

Question

<?php 
    $result = mysql_query("SELECT * FROM articles WHERE tag='sports'"); 
    $strss=$strss+1; 
     while ($row = mysql_fetch_array($result)) 
      { 
     echo '<li id="nav'.$strss.'"><a href="#" >'.$row['title'].'</li>'; 
      } 
?> 

爲什麼我不能自動設置數字？數量始終是1

Answer 1

您需要將您的櫃檯while循環中像下面這樣：

<?php 
    $result = mysql_query("SELECT * FROM articles WHERE tag='sports'"); 
    $strss=1; 
     while ($row = mysql_fetch_array($result)) 
      { 
       echo '<li id="nav'.$strss.'"><a href="#" >'.$row['title'].'</li>'; 
       $strss++; 
      } 
?> 

Answer 2

因爲增量是外循環。
