-PHP is a server-side language. When a web request for PHP file comes in, the web server processes the PHP file to produce HTML output.  That is, the main function of most PHP scripts is to dynamically create HTML content.  PHP5 support for Apache is provided by mod_php5. In Ubuntu, you can provide PHP5 support by installing ''php5''. This will install the apache2 module and the php5 command line interpreter (useful for debugging). PHP files may have different extensions, but ''.php'' is the most common.  In the Apache configuration, you can specify which extensions are going to be treated as PHP scripts by adding the extensions to the list in the ''/etc/httpd/conf.d/php.conf'' file:

 Another useful function to know is the ''readfile'' function.  It takes a file on the webserver's file system and sends it to the web browser.  A simple example is given below, but note that you'll probably need to specify addition header fields in order to have the web browser download the file correctly.

-When you use a ''file'' input in a form, PHP automatically adds an entry in the ''$_FILES'' array with information about the file. For example, transfer.php called the file ''uploadedfile'', so $_FILES['uploadedfile'] refers to file that the user selected in the form.  The name of the original file is $_FILES['uploadedfile']['name'].   When you upload a file, it is put in a temporary location by the web server. This temporary name is $_FILES['uploadedfile']['tmp_name']. In PHP, you can move a file from its original location to a new location by calling a built-in function, ''move_uploaded_file'', which takes an argument for the source (temporary location) and destination location. Note that relative paths in the destination location are relative to the location of the PHP script being executed.

 ===Self-Submitting Forms===
 Oftentimes we don't want to pass form values to a different page, but rather to the same page as contains the form so that we can process the information and display output on that same page. The way we do this is to specify that the form should submit to $_SERVER['PHP_SELF'] and not say, other_page.php.
