variable in url [php4]

[Anon]

it's maybe a silly question, but ... i've got a php-script (example.php) and if i call it in the browser with "example.php?action", i want the function "action()" to be executed ... how could i do that? tia.

While I am not sure that you can actually call the function, something close would look like this:

Using the URL:
example.php?action

Contents of example.php:
<?php
switch($QUERY_STRING) {
case "action":
<execute instructions or function>
break;
default:
break;
}
?>

Hi,
The only way I know of would be to call it like this.....
example.php?whatToDo=action
where whatToDo is a variable, and action the value of the variable. So in your example.php, you could have

if($whatToDo=="action")
action();

Hope that helps....

look into using eval:
