Is there a good description of the -> operator anywhere or can anyone please explain it. I'm an experienced but amateur PHP programmer and see -> used in examples and libraries but cannot find any documentation of it on the w3Schools site, at php.net or elsewhere. Here's an example: if (!$fh = fopen($this->_outputFile, 'wb+')) { return 'error opening outputfile: '.$this->_outputFile.' for wb+ access!';} Many thanks
