param: string $varname  The variable name to check.
param: mixed $default   Default value if the variable isn't present
return: mixed  $default if the var is in user input or not present,

formInput($append_session = 0)   X-Ref
Returns a hidden form input containing the session name and id.

return: mixed  $var, minus any magic quotes.

getFormData($var, $default = null)   X-Ref
Gets a form variable from GET or POST data, stripped of magic quotes if
necessary. If the variable is somehow set in both the GET data and the
POST data, the value from the POST data will be returned and the GET
value will be ignored.

param: string $var      The name of the form variable to look for.
param: string $default  The value to return if the variable is not
return: string  The cleaned form variable, or $default.

getGet($var, $default = null)   X-Ref

param: string $var      The name of the form variable to look for.
param: string $default  The value to return if the variable is not

param: string $prefix   Prefix to make the temporary name more
param: boolean $delete  Delete the file at the end of the request?
param: string $dir      Directory to create the temporary file in.
param: boolean $secure  If deleting the file, should we securely delete
return: string   Returns the full path-name to the temporary file.

getTempFileWithExtension($extension = '.tmp',$prefix = '',$delete = true, $dir = '',$secure = false)   X-Ref
Creates a temporary filename with a specific extension for the lifetime
of the script, and (optionally) registers it to be deleted at request
shutdown.

param: string $extension  The file extension to use.
param: string $prefix     Prefix to make the temporary name more
param: boolean $delete    Delete the file at the end of the request?
param: string $dir        Directory to create the temporary file in.
param: boolean $secure    If deleting file, should we securely delete

called with a directory will remove that directory and all files in that
directory at request shutdown.

If called with no arguments, return all elements to be deleted (this
should only be done by Horde_Util::_deleteAtShutdown()).

The first time it is called, it initializes the array and registers
Horde_Util::_deleteAtShutdown() as a shutdown function - no need to do
so manually.

The second parameter allows the unregistering of previously registered
elements.

param: string $filename   The filename to be deleted at the end of the
param: boolean $register  If true, then register the element for
param: boolean $secure    If deleting file, should we securely delete

shutdown()   X-Ref
Deletes registered files at request shutdown.

This function should never be called manually; it is registered as a
shutdown function by Horde_Util::deleteAtShutdown() and called
automatically at the end of the request.

Contains code from gpg_functions.php.
