Upload large files to FTP with PHP

Question

I'm trying to upload large files with php to an ftp server. I can upload small files, but I'm having trouble uploading larger files. I have looked it up and found that I need to set upload_max_filesize and post_max_size, set ftp to passive mode, and set time limit to never. I had no luck with setting the time limit, and what I have now isn't returning any errors, but it is also not uploading the file. If you look at the if (!$upload) { line at the bottom, it should echo something, but it isn't. More importantly, it just isn't working. Any insight as to what is going wrong or what I need to do to make this work? Thank you!

ini_set('upload_max_filesize', '50M');   
ini_set('post_max_size', '50M');  

$conn_id = ftp_connect($ftp_server);

// login with username and password
$login_result = ftp_login($conn_id, $ftp_user_name, $ftp_user_pass);

// check connection
if ((!$conn_id) || (!$login_result)) {
        echo "FTP connection has failed!";
        echo "Attempted to connect to $ftp_server for user $ftp_user_name";
        exit;
}

 // turn passive mode on
ftp_pasv($conn_id, true);

if($_FILES['upload_file']['name']!=''){
    $source_file = $_FILES['upload_file']['tmp_name'];
    $destination_file = $_FILES['upload_file']['name']; 

    // upload the file
    $upload = ftp_put($conn_id, $destination_file, $source_file, FTP_BINARY);

    // check upload status
    if (!$upload) {
            echo "FTP upload has failed!<br />";
        } else {
            echo "Uploaded $source_file to $ftp_server as $destination_file<br />";
        }       
}

UPDATE

I've discovered that I cannot set the upload_max_filesize value from the php page; also, I can't seem to get .htaccess to work: if I have an .htaccess file it results in a HTTP Error 500. Also, I don't have access to php.ini.

How else can I change the upload_max_filesize value?

More Information

My web administrator has told me that I am on an IIS windows-based system, so .htaccess files won't work. Is there a way that I can affect the file upload size with web.config?

some hosting companies will only let you set that so high. Also, rather than setting it everytime the script runs, why not just put it in the php.ini file? — Rooster, May 01 '12 at 14:49
Is the page loading for ever? If not, the reason that it doesn't echo something must be because `$_FILES['upload_file']['name']` is `''`. And make sure error reporting is on. — Sietse, May 01 '12 at 14:49
@Sietse How do I turn error reporting on? It will upload small files, but not large files. — bozdoz, May 01 '12 at 14:50
You sure set_time_limit() is working? Some hosts require you to make a php.ini file in the directory where your php file resides. — fhugas, May 01 '12 at 14:57
for the web config, maybe you can have a look at the http runtime section: http://msdn.microsoft.com/en-us/library/e1f13641.aspx — Sauleil, May 04 '12 at 14:53

From this site: http://www.php.net/manual/en/ini.php

'upload_max_filesize' and 'post_max_size'

are of type PHP_INI_PERDIR

which means Entry can be set in "php.ini, .htaccess or httpd.conf". So you can't set it in your script.

Personally, I wanted to do the same kind of stuff (upload large files over ftp) and end up writing a java application. For handling large files, php is not really the best way. Web browsers doesn't really like that. So, for handling large files, I would suggest to look at other alternative: (java, swf, javascript, ...)

Something I would like to give a try when I have some time is http://nodejs.org/

as rightly pointed out by @AngeDeLaMort, you cannot use shorthand notation to set configuration values outside of PHP.ini.

reference : Changing upload_max_filesize on PHP

try doing it this way.

create .htaccess file in your root directory and add the following.

php_value upload_max_filesize 50M
php_value post_max_size 50M
php_value max_execution_time 200
php_value max_input_time 200

Page cannot be displayed when I create an .htaccess file: HTTP Error 500 – bozdoz May 01 '12 at 15:02
do you have any other rule set up in your .htaccess file? – Ibrahim Azhar Armar May 01 '12 at 15:03

please make sure you place .htaccess file in the correct directory. – Ibrahim Azhar Armar May 01 '12 at 15:14
I put it in the same directory as the php page. It results in an HTTP Error 500 – bozdoz May 01 '12 at 15:16
place the file in the root directory, i.e if you are using linux server then directly in `public_html` directory or in windows `www` directory. – Ibrahim Azhar Armar May 01 '12 at 15:24
