謝謝朋友們的幫助和反饋。我知道我不擅長 PHP，但仍在嘗試學習和使用它：D——我的表包含針對 evaid 作為 Open Close 或 In Process 的重復(fù)條目——使用下面的代碼，我從 DB 中獲得了每個條目的最后輸入狀態(tài)通過使用查詢和 if 語句來顯示數(shù)據(jù)的狀態(tài)，但我也想獲取它的計數(shù)。任何人都可以幫助我---例如---$sql = "SELECT * FROM (SELECT * FROM disagreements ORDER BY addeddate DESC) disagreements  GROUP BY evaid";$result = mysqli_query($conn, $sql);if (mysqli_num_rows($result) > 0) {     while($row = mysqli_fetch_assoc($result))  {   // Here with this query I got last entered status of each row against evaid – as 2 Open – 5 in Process and 10 Closed --- with below if statement – I can echo the rows with status but I want to have count of it that how many are open, in process or closed        if($row["status"]=='Open') {  // I want to count this value as 2                    echo "<tr>";            echo "<td>" . $row["evaid"]. "</td>";            echo "<td>" . $row["status"]. "</td>";            echo "</tr>";        }     }} else {    echo "Nothing to Display";}mysqli_close($conn);
