I try to determine some data externally through an PHP programme with the 'exec' module. Everything is fine as long as I do only return one value from PHP, the return attribute is duly accepted and processed. As soon as I return more than one the exec module gets confused, as everything is returned in one long string (see debug output). There is no documentation in the echo or exec module as far as I can see, so I tried spaces, \r\n, and commas ',' as delimiters. Nothing worked. Is this a limitation of the exec module, that it only accepts one reply value back? The name of the parameter 'output_pairs' seems to suggest otherwise. Can anyone advise on the proper delimitation of multiple return values? BTW, thanks everyone for all their help so far. Debug output: ...
