Save a piece of data to a txt file in PHP and display its content, _PHP Tutorial

Save a piece of data into a txt file in php and display its content,

The data here can be basic data types, arrays, objects, etc.;

You can use serialize to serialize when storing, but you must first use unserialize to deserialize when retrieving.

<&#63;php
  $data = array("上海","西安","北京");

  //将数组存到指定的text文件中
  file_put_contents("E:/data.txt",serialize($data));
  //获取数据
  $datas = unserialize(file_get_contents("E:/data.txt"));
  print_r($datas);
&#63;>

Of course, you can also use json_encode. The array here can be accessed as key-value pairs, and you need to use json_decode to escape when accessing.

<&#63;php
  $data = array("现代"=>"上海","文化"=>"西安","首都"=>"北京");

  //将数组存到指定的text文件中
  file_put_contents("E:/data.txt",json_encode($data));
  //获取数据
  $datas = json_decode(file_get_contents("E:/data.txt"));
  print_r($datas);
&#63;>
