PHP saves a piece of data to a TXT file and displays its contents, _php tutorial

PHP saves a piece of data in a TXT file and displays its contents,

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

It can be serialized with serialize when it is stored, but it should be deserialized with unserialize first when it is taken.

<?php  $data = Array ("Shanghai", "Xian", "Beijing");  Saves the array to the specified text file  file_put_contents ("E:/data.txt", Serialize ($data));  Get data  $datas = Unserialize (file_get_contents ("E:/data.txt"));  Print_r ($datas);? >

Of course, you can also use Json_encode, where the array can be accessed by key-value pairs, which are escaped with Json_decode.

<?php  $data = Array ("modern" = "Shanghai", "culture" = "Xi ' an", "capital" = "Beijing");  Saves the array to the specified text file  file_put_contents ("E:/data.txt", Json_encode ($data));  Get data  $datas = Json_decode (file_get_contents ("E:/data.txt"));  Print_r ($datas);? >
