Question

需要帮助来构建这样的表https://datatables.net/examples/data_sources/ajax.html

我在mysql中有近50万行的表。我想通过ajax在jQuery Datatable中加载neary 10k行。我怎么这样格式化？

{
  "data": [
    [
      "Tiger Nixon",
      "System Architect",
      "Edinburgh",
      "5421",
      "2011/04/25",
      "$320,800"
    ],
 ...
   [
      "Garrett Winters",
      "Accountant",
      "Tokyo",
      "8422",
      "2011/07/25",
      "$170,750"
    ]
 ]
}

来自这个

foreach ($query as $result){
  ... $result['msgid'], $result['msgdate']...
}

我现在尝试的是

$a = '
{
  "data": 
  [';
  foreach($q as $r){ 
    $a.= '[
      "'.$r['msgid'].'",
      "'.$r['msgdate'].'"
    ],';
  }
  $a = rtrim($a,',');
  $a.=']
}';
echo $a;

Answer 1

您可以使用json_encode功能

Answer 2

首先我会改变：

$a = '
{
  "data": 
  [';
  foreach($q as $r){ 
    $a.= '[
      "'.$r['msgid'].'",
      "'.$r['msgdate'].'"
    ],';
  }
  $a = rtrim($a,',');
  $a.=']
}';
echo $a;

要：

echo json_encode(array('data' => $a));

您也可以更改php.ini文件中的max_execution_time。也请考虑这种方式：

    $a = array();
    $result = mysqli_query($con,$sql);
    while($row = mysqli_fetch_assoc($result)) {
         array_push($a, $row ); 
    }
