PHP writes a file multi-server synchronization program,

The examples in this article share with you the PHP file multi-server synchronization tool. The specific content is as follows:

<? Phpheader ('content-type: text/html; charset = UTF-8 '); // file name: php file multi-server synchronization tool // file function: the server where the file is located is the master server, the server where other files are stored can be used for shunting or backup. This file requires the jQuery library. You can also chain others' // last modification time: 2016-06-30 // BY: strwei if (! Empty ($ _ POST ['files']) sync (); function sync () {$ aFiles = explode ("\ n ", $ _ POST ['files ']); // var_dump ($ aFiles); exit; foreach ($ aFiles as $ k =>v v) {if (strlen ($ v) <= 5) unset ($ aFiles [$ k]);} array_filter ($ aFiles); if (empty ($ aFiles) {echo 'no file'; exit ;} $ aFTPServers = array ('server1' => array ('strwei. com ', 'ftp Username', 'ftp password', 'default directory when FTP is enabled '), // FTP address, username, password, default directory when FTP opens this site // 'server2' => array ('yy. 9.je ', 'Ftp username', 'ftp password', 'default directory when FTP is enabled'),); $ aAbortFile = array('robots.txt '); $ aErrors = array (); $ iError = count ($ aErrors); $ aSuc = array (); foreach ($ aFTPServers as $ ftp) {$ conn = ftp_connect ($ ftp [0]); if (empty ($ conn) {$ iError = $ iError + 1; array_push ($ aErrors, $ iError.

Empty ($ ftp [3]) $ ftp_root = ftp_chdir ($ conn, $ ftp [3]); $ ftp_root = ftp_pwd ($ conn); if (substr ($ ftp_root, -1) = '/') $ ftp_root = substr ($ ftp_root, 0,-1); foreach ($ aFiles as $ k => $ v) {$ s = basename ($ v); if (in_array ($ s, $ aAbortFile) {$ iError = $ iError + 1; array_push ($ aErrors, $ iError.
