A good way to implement file upload in PHP_PHP tutorial

P & GT; There are many personal homepage spaces that support PHP on the Internet. At this time, you may think of something uploaded, but after all, it is free. Of course, there will be a lot of restrictions. Even the Mail() function is not used. In this case, there is no way to upload. PHP supports powerful sockets. Of course, direct operation of ftp is indispensable. Just look at the function table and you can upload files through ftp. Isn’t it great? Don’t we use ftp to upload the home page?
The implementation code is as follows:
//upload.php

Upload file:

$ftp_server="ftp server (preferably use IP)";
$ftp_username="ftp username";
$ftp_password="Login password";
$ftp_dir="Directory (such as Set to /)";
if ($action == "OK")
{
$con = ftp_connect($ftp_server); //Connect ftp
ftp_login($con, $ftp_username, $ftp_password); //User login
$suss=$con;
ftp_chdir($suss, $ftp_dir); //cd to the specified directory
$ok_code = ftp_put($suss, $upload_file_name, $ upload_file, FTP_BINARY); //put file

if ($ok_code == 1)
{
echo "File uploaded successfully!";
}
else
{
echo "File upload failed!";
}
ftp_quit($suss); // Close ftp connection
}
?>
