PHP true static cache ob system function PHP function return value PHP array php date Letter

True static caching: (really generates an HTML page that calls the HTML directly in the next operation)
The first time (refresh the Web page) to determine if there is a cache file (can be set one time)
If there is no first time is (can be based on PDO) connection database lookup data output to a page and simultaneously cache (write) to a local. html file;
Once again (refresh the Web page) to determine if the cache file is stored
When a cache file exists, a direct lookup of the local cache (file_get_content) is read out

The following code is written in the CI framework

   $time  =  ten ; //Set Cache page Expiration Time   if  (!is_file ( "obtest.html" ) | | time ()-filemtime ( "obtest.html" );  $time )       {Ob_start (); //Open buffer   $arr  [ Res ' ]=  $this ->db->get ( ' user ' )->result_array ();  $this ->load->view ( ' welcome_message ' ,  $arr ); //print_r ($arr);         $info  = ob_get_contents (); //Get the contents of the buffer and assign a value to $info    $file  =  fopen  ( ' obtest.html ' ,  ' W ' ); //Open file Info.txt   fwrite        ( $file ,  $info ); //write information to Info.txt   fclose           ( $file ); //Close file Info.txt }  Else     {echo  "cache:" ; Echo file_get_contents ( "obtest.html" );}  

Use of the fopen and Filemtime methods:

fopen() 函数打开文件或者 URL。fopen（文件名称，文件访问类型）w写入方式打开。filemtime() 函数返回文件内容上次的修改时间，里面跟文件名。

'). addclass (' pre-numbering '). Hide (); $ (this). addclass (' has-numbering '). Parent (). append ($numbering); for (i = 1; i <= lines; i++) {$numbering. Append ($ ('

'). Text (i)); }; $numbering. FadeIn (1700); }); });

The above describes the PHP true static cache OB system functions, including PHP, functional aspects, I hope that the PHP tutorial interested in a friend to help.
