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.
<?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);
?>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.
<?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);
?>
