Tutorial
6.To
upload a file to the server
--------------------------------------------
|
|
FTP(File Transfer Protocol) Upload can be
done using a PHP script.
In the case of files, the usual $_POST or $_GET
global array variable cannot be used .
$_FILES global variable array has the file path to be
uploaded (if the file to be uploaded is selected using the browse
button).
The file chosen is usually stored in a temporary
location.It has to be moved to the required destination path using the
following built-in function
The move_uploaded_file() function moves the file
(from the temporary location) to the specified path in the server.
this function returns false if the file has not been
successfully uploaded to the destination path else it returns true.

<?php
if($_FILES)
{
$uploaddir = '/projects/www/cms/training/';
$filename=$_FILES['userfile']['name'];
$uploadfile = $uploaddir . $filename;
if(preg_match("/(.*)\.bmp/",basename($_FILES['userfile']['name'])))
{
echo
"<font color=red size=4>Bitmap File cannot be
uploaded</font>";
exit;
}
if($_FILES['userfile']['size']>1000000)
{
echo
"<font color=red size=4>The file size exceeds
1000KB</font>";
exit;
}
if(move_uploaded_file($_FILES['userfile']['tmp_name'],$uploadfile))
{
echo
"<font color=green size=4>The file $uploadfile has been
successfully uploaded to the path $uploaddir</font>";
}
else
{
echo
"<font color=red
size=4>The file $uploadfile cannot be uploaded to the path
$uploaddir</font>";
}
}
?>
