Docs For Class PEAR

[line 107]
PEAR command class, a simple factory class for administrative commands.

How to implement command classes:

The class must be called PEAR_Command_Nnn, installed in the "PEAR/Common" subdir, with a method called getCommands() that returns an array of the commands implemented by the class (see PEAR/Command/Install.php for an example).

The class must implement a run() function that is called with three params:

(string) command name (array) assoc array with options, freely defined by each command, for example: array('force' => true) (array) list of the other parameters

The run() function returns a PEAR_CommandResponse object. Use these methods to get information:

int getStatus() Returns PEAR_COMMAND_(SUCCESS|FAILURE|PARTIAL) *_PARTIAL means that you need to issue at least one more command to complete the operation (used for example for validation steps).

string getMessage() Returns a message for the user. Remember, no HTML or other interface-specific markup.

If something unexpected happens, run() returns a PEAR error.

DON'T OUTPUT ANYTHING! Return text for output instead.

DON'T USE HTML! The text you return will be used from both Gtk, web and command-line interfaces, so for now, keep everything to plain text.

DON'T USE EXIT OR DIE! Always use pear errors. From static classes do PEAR::raiseError(), from other classes do $this->raiseError().
