  1. 使用json_encode()将PHP数组转换为JSON格式数据:
$data = array("name" => "John", "age" => 30, "city" => "New York");
$json_data = json_encode($data);
echo $json_data;
  1. 使用json_decode()将JSON格式数据转换为PHP数组:
$json_data = '{"name": "John", "age": 30, "city": "New York"}';
$data = json_decode($json_data, true);
print_r($data);
  1. 处理JSON数据中的嵌套数组:
$json_data = '{"name": "John", "age": 30, "address": {"street": "123 Main St", "city": "New York"}}';
$data = json_decode($json_data, true);
echo $data['address']['city'];
  1. 处理JSON数据中的数组:
$json_data = '{"name": "John", "age": 30, "hobbies": ["reading", "running", "cooking"]}';
$data = json_decode($json_data, true);
foreach ($data['hobbies'] as $hobby) {
    echo $hobby . "<br>";
}
  1. 处理JSON数据中的日期格式:
$json_data = '{"date": "2022-01-01"}';
$data = json_decode($json_data, true);
$date = date("Y-m-d", strtotime($data['date']));
echo $date;

这些是一些常见的实战技巧,可以帮助您更好地处理和操作JSON数据。
