com_invoke (PHP 3 >= 3.0.3) com_invoke --
Calls a COM component's method [deprecated]
Descriptionmixed com_invoke ( resource com_object, string function_name [, mixed function_parameters] )
com_invoke() invokes the method
named function_name of the COM
component referenced by com_object.
com_invoke() returns FALSE on error,
returns the function_name's return
value on success. All the extra parameters
function_parameters are passed to
the method function_name.
Example 1. Don't use com_invoke(), use OO syntax instead |
<?php
$val = $obj->method($one, $two);
$val = com_invoke($obj, 'method', $one, $two);
?>

Note:
This function does not exist in PHP 5; instead, you should use the regular
and more natural OO syntax to access properties or call methods.

Note that if you want to use a string to specify the method to call (e.g. a drop-down list to decide what to do to a server process) you can do this in three ways.
The first is to use this function, as in <?php com_invoke($obj, $_GET['func']); ?>
That's bad.
The second is to use eval(), as in <?php eval("\$obj->{$_GET['func']}();"); ?>
That's very very very *very* bad.
The third is to use call_user_func(), as in <?php call_user_func(array($obj, $_GET['func'])); ?>
That's very good.
Remember to validate the user input against a list of allowed methods if a non-admin is at the console.
