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']
