This code seems to be duplicated across your project.

					$name = substr($name, 0,  strlen($name)-strlen($m[0]));
				}

				$archive = $result.DIRECTORY_SEPARATOR.basename($path);

				if (!$this->_mkdir(dirname($path), $name) || !copy($path, $archive)) {

The expression $this->_mkdir(dirname($path), $name) of type string|false is loosely compared to false; this is ambiguous if the string can be empty. You might want to explicitly use === false instead.

					return false;
				}
				
				$this->_unpack($archive, $arc);
				@unlink($archive);

It seems like you do not handle an error condition here. This can introduce security issues, and is generally not recommended.

			return file_exists($result) ? $result : false;

The expression file_exists($result) ? $result : false; of type string|false adds the type string to the return on line 733 which is incompatible with the return type declared by the abstract method elFinderVolumeDriver::_extract of type boolean.
