{
"apple":[
"get",
"get me an apple"
],
"orange":[
"get me one",
"get some"
],
"banana ":[
"cut them all",
"get them"
],
}
如何获取格式？当我使用 print_r（$sql） 打印短语和操作列时，我的 SQL 输出;是
Array ( [phrases] => get [actions] => apple )
Array ( [phrases] => get me an apple [actions] => apple )
Array ( [phrases] => Get me one [actions] => orange )
Array ( [phrases] => Get some [actions] => orange )
Array ( [phrases] => cut them all [actions] => Banana )
Array ( [phrases] => get them [actions] => Banana )
请帮忙。提前感谢.....
简单尝试一下：
$tempArray = array();
while($rec = mysql_fetch_assoc($sql)){
$tempArray[$rec['actions']][] = $rec['phrases'];
}
echo json_encode($tempArray);
存储在
$sql 变量中的内容数据类型为 array 。要将数组转换为其各自的 json 字符串表示形式，您需要对其进行编码。
标准 PHP 库通过 json_encode 提供此功能。
以下代码片段应完成示例中的工作：
$tmp = [];
foreach ($sql as $row) {
$response[$row['actions']][] = $row['phrases'];
}
$json = json_encode($tmp);
