顯示php表格的數據和計算

Question

我寫了一個php文件，它想要打印出的電子郵件總數（總數），發送的電子郵件數量（發送）以及電子郵件數量還沒有發送給每個天。這裏是我的php文件如下

<?php  
    $total =0; 
    $sent =0; 
    $pending = 0; 
    $sql = "SELECT `sflag` , `thedate` FROM `ecard2008` WHERE `thedate` >= '2013-12-12'"; 
    $list_mysql = mysql_query($sql) or mysql_error(); 
    while($list = mysql_fetch_array($list_array)) { 
     $sflag = $list['sflag']; 
     $date = $list['thedate']; 
     if ($sflag == 0) { 
      $pending = $pending + 1; 
     } 
     else { 
      $sent = $sent + 1; 
     } 
     $total = $total + 1; 
    } 
    echo "<table border='1'> 
    <tr> 
     <th>Date</th> 
     <th>Daily volume</th> 
     <th>Sent</th> 
     <th>Pending</th> 
    </tr>"; 

    echo "<tr>\n"; 
    echo "<td>" . $date . "</td>"; 
    echo "<td>" . $total . "</td>"; 
    echo "<td>" . $sent . "</td>"; 
    echo "<td>" . $pending . "</td>"; 
    echo "</tr>"; 

    echo "</table>"; 
?> 

不幸的是，輸出只顯示錶和表的第一行。無法顯示電子郵件的數量。我能做些什麼來顯示這些數字。

好...你嘗試使用mysqli的，

<?php 
// Create connection 
$con=mysqli_connect("localhost","user","password","database"); 

// Check connection 
if (mysqli_connect_errno($con)) 
    { 
    echo "Failed to connect to MySQL: " . mysqli_connect_error(); 
    } 


$sql = "SELECT 'thedate', count(sflag) as total, SUM(CASE WHEN sflag = '1' THEN 1 ELSE 0 END) 'sent', SUM(CASE WHEN sflag= '0' THEN 1 ELSE 0 END) 'pending' FROM 'ecard2008' WHERE 'thedate' >= '2013-12-12' group by 'thedate'"; 

$list_mysql = mysqli_query($con, $sql); 

echo "<table border='1'> 
<tr> 
<th>Date</th> 
<th>Daily volume</th> 
<th>Sent</th> 
<th>Pending</th> 
</tr>"; 


while($list = mysql_fetch_array($list_mysql)) { 

echo "<tr>\n"; 
echo "<td>" . $list['thedate']. "</td>"; 
echo "<td>" . $list['total'] . "</td>"; 
echo "<td>" . $list['sent'] . "</td>"; 
echo "<td>" . $list['pending'] . "</td>"; 
echo "</tr>"; 

} 

echo "</table>"; 

?>

只是一些基本的調試改變這一行：

while($list = mysql_fetch_array($list_array)){ 

這樣：

while($list = mysql_fetch_array($list_mysql)){ 

沒有名爲$ list_array變量。

<?php  
$sql = "SELECT 'thedate', count(sflag) as total, SUM(CASE WHEN sflag = '1' THEN 1 ELSE 0 END) 'sent', SUM(CASE WHEN sflag= '0' THEN 1 ELSE 0 END) 'pending' FROM 'ecard2008' WHERE 'thedate' >= '2013-12-12' group by 'thedate'"; 

$list_mysql = mysql_query($sql) or mysql_error(); 

echo "<table border='1'> 
<tr> 
    <th>Date</th> 
    <th>Daily volume</th> 
    <th>Sent</th> 
    <th>Pending</th> 
</tr>"; 


while($list = mysql_fetch_array($list_mysql)) { 

echo "<tr>\n"; 
echo "<td>" . $list['thedate']. "</td>"; 
echo "<td>" . $list['total'] . "</td>"; 
echo "<td>" . $list['sent'] . "</td>"; 
echo "<td>" . $list['pending'] . "</td>"; 
echo "</tr>"; 

} 

echo "</table>"; 
?>
