I don't believe the disputed line of script is being executed because just before that line I include the following print statement, echo "array size: " . count($zip_forward) . " ID: $location_id<br>"; which does not get executed when my conditional fails.
Right you are on the error reporting, I included error_reporting (E_ALL); in my test script and can reproduce same error on Apache. Chris "John W.
