The expression $this->css_url of type array is implicitly converted to a boolean; are you sure this is intended? If so, consider using ! empty($expr) instead to make it clear that you intend to check for an array without elements.

			$num = count($this->css_url);

			//get files and check their bodies
			foreach ( $this->css_url as $val ) {
				$body = @file_get_contents( $val, FILE_USE_INCLUDE_PATH );

NirjharLo\Cgss\Lib\Analysis\Lib\FILE_USE_INCLUDE_PATH of type integer is incompatible with the type boolean expected by parameter $use_include_path of file_get_contents().
