動態表與PHP

Question

我想用PHP創建一個動態表。行數將基於從mysql中提取的記錄數量，但我只希望一行中有4行。以下是我現在所擁有的

$sql = "SELECT t.tankid,t.TankName,tc.paramid,tc.active,pr.paramname,pr.minvalue,pr.maxvalue,pr.incvalue,pr.value from mr_tanks t inner join mr_testconfig tc ON tc.tankid = t.tankid inner join mr_parameters pr ON tc.paramid = pr.parameterid where t.tankid = :tankid and t.active = 1 and tc.active = 1"; 
$records1 = $con->prepare($sql); 
$records1->bindParam(':tankid', $_GET['tankid']); 
$records1->execute(); 
$headers = $col = ""; 
while ($row1 = $records1->fetch(PDO::FETCH_ASSOC)) { 
    $headers .= "<th> {$row1['paramname']} </th>"; 
    $col .= "<td> {$row1['minvalue']} </td>"; 
} 
echo "<table><tr>$headers</tr><tr>$col</tr></table>"; 
?> 

什麼，我得到的是所有行均符合這樣的：

標題1個標題2標題3標題4標題5標題6標題7標題8
數據1數據2數據3數據4 數據5數據6數據7數據8

而且我想它是

標題1標題2標題3標題4
數據1數據2數據3數據4
頭5頭6頭7頭8
數據5數據6數據7數據8 孔

     <td> ResultTest 6</td>

    </tr> 
</table>   

Answer 1

您可以將行分塊爲2維數組，然後遍歷它們，其中每個塊將爲您提供一個單獨的表，每個表中有4行。

如果最後一個塊的行數少於4行，您可以決定讓表格少於4列，或者仍然需要它爲4列，然後使用空的參數名/ minvalue添加填充行。

$results = array(); 
while ($row1 = $records1->fetch(PDO::FETCH_ASSOC)) { 
    $results[] = $row1; 
} 

$results = array_chunk($results, 4); 
foreach($results as $chunk) { 
    $headers = ""; 
    $col = ""; 
    foreach($chunk as $row) { 
    $headers .= "<th> {$row)['paramname']} </th>"; 
    $col .= "<td> {$row)['minvalue']} </td>"; 
    } 
    echo "<table><tr>$headers</tr><tr>$col</tr></table>"; 
}
