PHP Remote upload file class instance with FTP detailed

This article mainly introduces PHP using FTP remote Upload file class examples, interested in the friend's reference, I hope to help you.

PHP uses FTP to implement file upload code snippet:

<?php/** * FTP upload File class */class FTP {/** * Test server * * @var array */Private $testServer = Array (' Host ' = ' IP ', ' port ' = ' + ', ' user ' = ' userName ', ' pwd ' = ' password ')     ; /** * Open and log on to server * * @param string $flag server Identity Test * @return Mixed * 0: Server Connection Failed * 1: Server Login Failed * Resource Connection ID */Public Function openserver ($flag = ' Test ') {//select server $config = $this-       >getserverconfig ($flag);       Connection Server $connect = Ftp_connect ($config [' Host '], $config [' Port '];       if ($connect = = false) return 0;       Log on to the server if (!ftp_login ($connect, $config [' User '], $config [' pwd '])) return 1;       Turn on Passive mode, the transfer of data is initiated by the client, not the server start FTP_PASV ($connect, true);     Returns the connection identifier return $connect;  }/** * Create directory and navigate directory to directory * * @param resource $connect Connection ID * @param string $dirPath directory path * @return       Mixed * 2: Failed to create directory *True: Create directory Success */Public Function MakeDir ($connect, $dirPath) {//process directory $dirPath = '/'.
