Create The Upload Script

The "upload_file.php" file contains the code for uploading a file:
< ?php
if ($_FILES["file"]["error"] > 0)
{
echo "Error: " . $_FILES["file"]["error"] . "< br / >";
}
else
{
echo "Upload: " . $_FILES["file"]["name"] . "< br / >";
echo "Type: " . $_FILES["file"]["type"] . "< br / >";
echo "Size: " . ($_FILES["file"]["size"] / 1024) . " Kb< br / >";
echo "Stored in: " . $_FILES["file"]["tmp_name"];
}
? >
By using the global PHP $_FILES array you can upload files from a client computer to the remote server.
The first parameter is the form's input name and the second index can be either "name", "type", "size", "tmp_name" or "error". Like this:
• $_FILES["file"]["name"] - the name of the uploaded file
• $_FILES["file"]["type"] - the type of the uploaded file
• $_FILES["file"]["size"] - the size in bytes of the uploaded file
• $_FILES["file"]["tmp_name"] - the name of the temporary copy of the file stored on the server
• $_FILES["file"]["error"] - the error code resulting from the file upload
This is a very simple way of uploading files. For security reasons, you should add restrictions on what the user is allowed to upload.
