Implementation code of FTP class like CodeIgniter

We will introduce you to the FTP class of CodeIgniter, which is very powerful and can be used as a reference for anyone who needs it. 1. file Upload ftp. php '', 'Username' =>'', 'password' => '', 'port' => ''...); */public function _ construct ($ config = array () {if (count ($ config)> 0) {$ this-> _ init ($ config );}} /*** FTP connection ** @ access public * @ param array configure array * @ return boolean */public function connect ($ config = array ()) {if (count ($ config)> 0) {$ this-> _ init ($ config );} if (FALSE ===( $ this-> conn_id = @ ftp_connect ($ this-> hostname, $ this-> port) {if ($ This-> debug === TRUE) {$ this-> _ error ("ftp_unable_to_connect") ;}return FALSE ;}if (! $ This-> _ login () {if ($ this-> debug === TRUE) {$ this-> _ error ("ftp_unable_to_login");} return FALSE ;} if ($ this-> passive === TRUE) {ftp_pasv ($ this-> conn_id, TRUE) ;}return TRUE ;} /*** Directory Change ** @ access public * @ param string Directory ID (ftp) * @ param boolean * @ return boolean */public function chgdir ($ path = '', $ supress_debug = FALSE) {if ($ path = ''OR! $ This-> _ isconn () {return FALSE;} $ result = @ ftp_chdir ($ this-> conn_id, $ path); if ($ result = FALSE) {if ($ this-> debug = true and $ supress_debug = FALSE) {$ this-> _ error ("ftp_unable_to_chgdir: dir [". $ path.
