[RESOLVED] detect if module is available w/out error/warning?

[Pileofrogs]

Hi, I'm relatively new to PHP, so please forgive if I should already know the answer to this.

I'm writing a PHP script that tests if my server is set up correctly. One thing I want to test is if certain optional modules are installed and available. Is there a way to run require() or include() and have them do something other than blurt big messy errors and/or kill the script? I want my script to be able to do things like proceed to check other modules, print a nice summary of results, send an email etc... Maybe there's a function that just looks for a module without trying to load it?

An obvious solution is to write an error handler and call set_error_handler() before trying to require_once() the module in question. Unfortunately, if the module isn't available, the script dies even if my handler doesn't want it to.

Thanks!

If you're referring to the various PHP extensions, try looking at [man]extension_loaded/man.

If not, depending on what you need, you can probably use something like [man]function_exists/man or [man]method_exists/man.

I figured it out! include() and include_once() issue non-fatal errors. set_error_handler catches the errors/warnings from include()/include_once(), so I'm good.
