CasperJS passing data back to PHP

Question

Answer 1

You can redirect output from stdout to an array.

On this page it says you can do:

string exec ( string $command [, array &$output [, int &$return_var ]] )

It goes on to say:

If the output argument is present, then the specified array will be filled with every line of output from the command.

So basically you can do exec('casperjs command here, $array_here);
