[英]add array element to row returned from sql query
I want to add an additional value into an array before passing it to json_encode function, but I can't get the syntax right. 我想在将其他值传递给json_encode函数之前将其添加到数组中,但是语法不正确。
$result = db_query($query);
// $row is a database query result resource
while ($row = db_fetch_object($result)) {
$stack[] = $row;
// I am trying to 'inject' array element here
$stack[]['x'] = "test";
}
echo json_encode($stack);
If it's an array you can directly add a value: 如果是数组,则可以直接添加一个值:
$row['x'] = 'test';
$stack[] = $row;
if it's an object you can add another property: 如果它是一个对象,则可以添加另一个属性:
$row->x = 'test';
$stack[] = $row;
if you want to keep the object and the extra value separated: 如果要使对象和附加值分开:
$data = array($row, 'x' => 'test');
$stack[] = $data;
but this does work. 但这确实有效。
$stack[] = $row;
$row->x = 'test';
How about something like: 怎么样:
$row['x'] = 'test';
$stack = $row;
