/**
*
* Fianl_m@foxmail.com
* Cache class
* Query the data and serialize the data into a file.
**/
Class Cache {

Function _ construct ($ config ){
// Define whether cache is enabled
$ This-> is_cache = $ config ['is _ cache'];
// Define the cache Directory
$ This-> cache_file = $ config ['cache _ file'];
// Define the cache time
$ This-> cache_time = $ config ['cache _ time'];


}

// Read the cached file
Public function open ($ name ){

$ Arr = array ();
$ Filename = $ this-> cache_file. $ name;
$ Status = filemtime ($ filename) + $ this-> cache_time> time (); // defines the cache time
If (file_exists ($ filename) & $ status & $ this-> is_cache ){
$ Content = file_get_contents ($ filename); // read the cached file
$ Arr = unserialize ($ content );
Return $ arr;
} Else {
Return false;
}

}
// Write the cached file
Public function write ($ name, $ data = array ()){
$ Filename = $ this-> cache_file. $ name;
$ Content = serialize ($ data );
File_put_contents ($ filename, $ content); // write the cached file

}

}

?>

In fact, it is nothing more than to serialize the select array into the text and then read it out.

Usage

// Define whether the cache is enabled
Require ('cache. class. php ');
$ Config = array (
'Is _ cache' => 1, // whether to enable the cache
'Cache _ file' => './cache/', // cache folder
'Cache _ time' => '60', // cache time
);
$ Cache = new Cache ($ config );

// Open the cache and input the cache file name

$ Row = $ cache-> open ($ filename );

// Write the file name and data (array) into the cache)

$ Cache-> write ($ filename, $ data );
