Answer 1

$post = mysql_fetch_assoc($postdb); 

返回第一個結果，然後向前移動遊標。

註釋掉此行並重試。

例子：

$postdb = mysql_query("SELECT * FROM wtable"); 
//$post = mysql_fetch_assoc($postdb); <-- comment out this line 

while ($poste = mysql_fetch_array($postdb)) { // <-- don't use @ here, we want to know if something went wrong! 
    echo $poste['posttitle']; 
    echo "<br />"; 
}
