Here's the code I'm working with:

function getFilePath($filename,$path=''){
		if(empty($path)){ $path=$this->basedir; }
		echo $path."<br>";
		if($dir=@opendir($path)){
			while(false!==($file=readdir($dir))){
				if(!in_array($file,$this->remove_array)){
					$file_path=$path."/".$file;
					if(is_file($file_path)){
						if(strtolower($file)==strtolower($filename)){
							$this->found_path=$file_path;
							return $file_path;
						}
					}elseif(is_dir($file_path)){
						$this->getFilePath($filename,$file_path);
					}
				}
			}
		}
		closedir($dir);
		//return $this->found_path;
	}

Where it starts in one dir, and goes until it finds a file - then, when it does, it's supposed to return that path value - but it doesn't. It keeps going through the rest of the directories without stopping at the "return"
