Php json_从MySQL编码-但在输出时更改列名

我从未真正使用过json_编码，但它很容易做到：

  $result = $dblink->query("SELECT * FROM Contracts LIMIT 3");

  $dbdata = array();

  while ( $row = $result->fetch_assoc())  {
    $dbdata[]=$row;
  }

  echo json_encode($dbdata);

/tada!

然而，如果我想给输出数据定制“列名”，有没有一种简单的方法

因此，与其输出类似于：

[{"TableColumn1":"147","TableColumn2":"9","TableColumn3":"39","TableColumn4":"32","TableColumn5":"41"...

[{"My Own Title":"147","My Own Title 2":"9","My own title 3":"39",...

我可以吃一些像：

[{"TableColumn1":"147","TableColumn2":"9","TableColumn3":"39","TableColumn4":"32","TableColumn5":"41"...

[{"My Own Title":"147","My Own Title 2":"9","My own title 3":"39",...

试试这个

$result = $dblink->query("SELECT * FROM Contracts LIMIT 3");

  $dbdata = array();

  while ( $row = $result->fetch_assoc())  {

    $rowarray = [];

    $rowarray['My Own Title 1'] = $row['TableColumn1'];
    $rowarray['My Own Title 2'] = $row['TableColumn2'];
    $rowarray['My Own Title 3'] = $row['TableColumn3'];

    $dbdata[]=$rowarray;

  }

  echo json_encode($dbdata);

为SELECT语句中的各个列设置别名，或者首先修改插入到

$dbdata

中的键…
