如何编辑“风”数组？例如，我希望速度为“3”？$forecast = [  "temperature" => "",  "precipitation" => array("min-value", "max-value"),  "wind" => [    "speed" => "",    "side" => "",  ]];

Answer 1

您可以通过以下方法修改数组：

$forecast['temperature'] = 100500

$forecast['wind']['speed'] = 3

你也可以从数组中获取数据：

$temperature = $forecast['temperature'];

$speed = $forecast['wind']['speed']
