The Ftp_connect () function establishes a new FTP connection.
If successful, returns a connection identity, or false.
Grammar
Host required. Specify the FTP server to connect to. Can be a domain name or an IP address.
The following should not end with a slash, and the front does not need to start with a ftp://.
Port Optional. Specify the port for the FTP server.
Timeout optional. Specify the timeout time for this FTP server. The default is 90 seconds.
Then a test was done locally on the desktop:
| The code is as follows |
Copy Code |
$ftp _server = "192.168.1.100";
$ftp _user_name = "Laohu";
$ftp _user_pass = "123456";
$conn _id = ftp_connect ($ftp _server) or Die ("couldn ' t connect to $ftp _server");
$file = ' test.txt ';
$remote _file = '/test/a.txt '; |
Note: the "/test" here refers to the test folder under the FTP root directory, not the system directory
Test
| The code is as follows |
Copy Code |
$login _result = Ftp_login ($conn _id, $ftp _user_name, $ftp _user_pass); if (Ftp_put ($conn _id, $remote _file, $file, ftp_binary)) {
echo "File move succeeded";
} else {
echo "Move Failed";
}
Ftp_close ($conn _id); |
After running: File moved successfully.
Want is this effect, and then use the desktop to do the program server, upload attachments full ftp method upload to the notebook, notebook IP is 105, phase
The code should read as follows:
| code is as follows |
copy code |
if (Is_uploaded_file ($_files[' uploadfile '] [' tmp_name '])) {
$ftp _server = "192.168.1.105";
$ftp _user_name = "Lesley";
$ftp _user_pass = "123456";
$conn _id = ftp_connect ($ftp _server) or Die ("couldn ' t connect to $ftp _server");
$file = $_files[' UploadFile '] [' tmp_name '];
$remote _file = '/test/'. $_files[' uploadfile ' [' name '];
$login _result = Ftp_login ($conn _id, $ftp _user_name, $ftp _user_pass); if (Ftp_put ($conn _id, $remote _file, $file, ftp_binary)) {
echo "File:". $_files[' UploadFile ' [' Name ']. " Upload Success ";
} else {
echo "Upload failed";
}
Ftp_close ($conn _id);
} |
The corresponding foreground page code:
| The code is as follows |
Copy Code |
<form action= "uploadfile.php" method= "post" enctype= "Multipart/form-data" >
<input type= "File" Name= "UploadFile" id= "UploadFile"/>
<input type= "Submit" name= "submit" value= "Submit"/>
</form> |
Did succeed after running.

Note that when using the Ftp_put method, the fourth parameter transfer mode needs to be ftp_binary (binary mode), with FTP_ASCII (text mode)
When the picture can be uploaded but can not be displayed, other files renamed, Chinese garbled solution, upload rights control, and so on, not mentioned here.
