File: <input type="file" name="file">
<input type="submit" name="submit" value="Upload">

if(isset($_POST['submit']))
{
$name=$_FILES['file']['name'];

{
move_uploaded_file($_FILES['file']['tmp_name'],dirname($_SERVER['DOCUMENT_ROOT']).'/oops/upload/files/'.$name);
echo'file added';

where,
$_FILES:
It is the php global variable. It keeps information about uploaded file like below.
$_FILES['file']['name'] - name of uploaded file.
$_FILES['file']['type'] - type of uploaded file.
$_FILES['file']['size'] - size of uploaded file.
$_FILES['file']['tmp_name'] - temporary name of uploaded file which is in server.
$_FILES['file']['error'] - errors while uploadeding file.
' file' is the name of <input> tag
$_SERVER['DOCUMENT_ROOT'] - return the directory.
move_uploaded_file()
- uploaded file to specified directory.
Now you can upload any file without any restriction using php. The file is stored in '/upload/file/' directory already if it is not present in the directory. Otherwise you'll get error message ' file is laready present'.
Great point and a nice article. I believe that if you write about whatever you are passionate about you will receive a lot larger following. People can tell when you write about something of value vs something to simply appease… I just found your blog, and look forward to seeing future updates even if they aren't daily posts… Keep up the good work
