使用PHP字典处理数据的示例

// 创建一个关联数组来存储数据$data = array(“name” => “John”,“age” => 30,“city” => “New York”);

// 输出数组中的某个值echo "Name: " . $data[‘name’] . “
”;echo "Age: " . $data[‘age’] . “
”;echo "City: " . $data[‘city’] . “
”;

// 修改数组中的某个值$data[‘age’] = 31;

// 输出修改后的值echo "Updated age: " . $data[‘age’] . “
”;

// 遍历整个数组并输出键值对foreach ($data as $key => $value) {echo $key . ": " . $value . “
”;}
