This article mainly introduces the example analysis of the FTP operation class in PHP, which has a certain reference value, and interested friends can refer to it. I hope you will gain a lot after reading this article.

/ * *

* function: FTP operation class (copy, move, delete files / create directories)

, /

Class class_ftp {

Public $off; / / returns the operation status (success / failure)

Public $conn_id; / / FTP connection

/ * *

* method: FTP connection

* @ FTP_HOST-- FTP host

* @ FTP_PORT-Port

* @ FTP_USER-user name

* @ FTP_PASS-password

, /

Function _ _ construct ($FTP_HOST,$FTP_PORT,$FTP_USER,$FTP_PASS) {

$this- > conn_id = @ ftp_connect ($FTP_HOST,$FTP_PORT) or die (FTP server connection failed)

@ ftp_login ($this- > conn_id,$FTP_USER,$FTP_PASS) or die ("FTP server login failed")

@ ftp_pasv ($this- > conn_id,1); / / Open passive simulation

}

/ * *

* method: upload files

* @ path-- Local path

* @ newpath-upload path

* @ type-- create a new directory if the destination directory does not exist

, /

Function up_file ($path,$newpath,$type=true) {

If ($type) $this- > dir_mkdirs ($newpath)

$this- > off = @ ftp_put ($this- > conn_id,$newpath,$path,FTP_BINARY)

If (! $this- > off) echo "File upload failed, please check the permissions and path is correct!"

}

/ * *

* method: move files

* @ path-- original path

* @ newpath-- New path

* @ type-- create a new directory if the destination directory does not exist

, /

Function move_file ($path,$newpath,$type=true)

{

If ($type) $this- > dir_mkdirs ($newpath)

$this- > off = @ ftp_rename ($this- > conn_id,$path,$newpath)

If (! $this- > off) echo "File movement failed, please check the permissions and the original path is correct!"

}

/ * *

* method: copy files

* Note: since there is no copy command in FTP, the flexible operation of this method is to download and upload to a new path.

* @ path-- original path

* @ newpath-- New path

* @ type-- create a new directory if the destination directory does not exist

, /

Function copy_file ($path,$newpath,$type=true) {

$downpath = "c:/tmp.dat"

$this- > off = @ ftp_get ($this- > conn_id,$downpath,$path,FTP_BINARY); / / download

If (! $this- > off) echo "File copy failed, please check the permissions and the original path is correct!"

$this- > up_file ($downpath,$newpath,$type)

}

/ * *

* method: delete files

* @ path-- path

, /

Function del_file ($path) {

$this- > off = @ ftp_delete ($this- > conn_id,$path)

If (! $this- > off) echo "failed to delete the file, please check the permissions and path is correct!"

}

/ * *

* method: generate a directory

* @ path-- path

, /

Function dir_mkdirs ($path) {

$path_arr = explode ('/', $path); / / fetch directory array

$file_name = array_pop ($path_arr); / / Pop-up file name

$path_div = count ($path_arr); / / number of layers

Foreach ($path_arr as $val) / / create a directory

{

{

$tmp = @ ftp_mkdir ($this- > conn_id,$val)

If ($tmp = = FALSE)

{

Echo "directory creation failed, please check the permissions and path is correct!"

Exit

}

@ ftp_chdir ($this- > conn_id,$val)

}

}

For ($ifoliance 1 / return to root) / / fallback to root

{

@ ftp_cdup ($this- > conn_id)

}

}

/ * *

* method: close the FTP connection

, /

Function close () {

@ ftp_close ($this- > conn_id)

}

/ / $ftp- > up_file ('aa.txt','a/b/c/cc.txt'); / / upload files

/ / $ftp- > move_file ('a _
