Recently I decided to upgrade some projects from my own (...) autoloader solution to a Composer PSR-4 autoloader. My code already followed PSR-4 so, no big deal there.
On a specific case, I had the following code:
public static function isAutoLoadable($className)
{
$className = ltrim($className, "\\");
$file = $GLOBALS["Path"] . "/src/" . str_replace("\\", "/", $className) . ".php";
if (false !== stream_resolve_include_path($file))
return $file;
return false;
}
It allowed me to check whatever a given class name could be loaded, without actually trying to load it and result on a PHP Class * not found error.
Use case: I'm currently using it to replace controllers that by some reason couldn't be found with a generic error one, avoiding an App crash and just telling the user something went wrong... then extra internal logging is done.
A function would be good since I can call it before trying to load a controller... I don't want this behavior to spread to any other classes on the app
So my question is: Is there a equivalent way to check if Composer is able to autoload some class without forcing it to load it and cause an error? -- So I can take further actions in case the class wasn't found?
