The html form :


<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>File Uploading With PHP and MySql</title>
</head>
<body>
<form action="" method="post" enctype="multipart/form-data">
<input type="file" name="pic" />
<button type="submit" name="btn-upload">upload</button>
</form>
</body>
</html>

Make Sure :
1 . Method="POST" : it should be POST.
2 . enctype="multipart/form-data" : it's specify content-type to be uploaded.
3 . type="file" : attribute of the input tag shows input field as a file selector with a "Browse" Button.

The PHP

We will use isset($_FILES['name_of_input']) to make sure some file is selected.
here in this following script javascript was just used for message that file was upload or not.
put this script just above <!DOCTYPE html> tag

<?php
if(isset($_POST['btn-upload']))
{
        $pic = rand(1000,100000)."-".$_FILES['pic']['name'];
        $pic_loc = $_FILES['pic']['tmp_name'];
        $folder="uploaded_files/";
        if(move_uploaded_file($pic_loc,$folder.$pic))
        {
            ?><script>alert('successfully uploaded');</script><?php
        }
        else
        {
            ?><script>alert('error while uploading file');</script><?php
} 
}
?>

PHP Script explained :
1 . $folder : Directory where files are uploaded.
2 . move_uploaded_files : php function that moves selected file to the specified folder.
3 . rand() : this is the awesome function that enables you to upload same files multiple times.

Complete Script

index.php

<?php
if(isset($_POST['btn-upload']))
{
     $pic = rand(1000,100000)."-".$_FILES['pic']['name'];
    $pic_loc = $_FILES['pic']['tmp_name'];
     $folder="uploaded_files/";
     if(move_uploaded_file($pic_loc,$folder.$pic))
     {
        ?><script>alert('successfully uploaded');</script><?php
     }
     else
     {
        ?><script>alert('error while uploading file');</script><?php
     }
}

?>
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>File Uploading With PHP and MySql</title>
</head>
<body>
<form action="" method="post" enctype="multipart/form-data">
<input type="file" name="pic" />
<button type="submit" name="btn-upload">upload</button>

    1. search for 'upload_max_filesize' in 'php.in' file and change it's value as you'r need, by default it's 2M
      for video set the value around 100M.
