什么是getScenarioPath和getScenarionResourceFolder？

Question

I am looking at someones project and keep getting this line:

$resource_folder = getScenarioResourceFolder(getScenarioPath($scenario));

I cannot find any function that he implemented under those two names - getScenarioResourceFolder and getScenarioPath. I started wandering that maybe the name Scenario has something to do with $scenario variable being in those functions. I know it might sound dumb, but I do not know what else to think.

Does anyone know about these function?

Answer 1

I know these:

1. You can search the function: http://id1.php.net/manual-lookup.php?pattern=getScenarioPath if no result, That is must be user-defined function.

2. You can check yourself by using

    if (function_exists('getScenarioPath')) {
        ...
     } else {
        ...
     }
