# Note: This is not secure! If you somehow get malicious code back from, this can run arbitrary code. Use wisely and sanitize your inputs!
# Replace with your API key and coordinates. Should be fine with other units and may work without excluding minutel and flags.
# I have only teste this format (hourly and daily with SI units). This works for Ottawa, Canada.
# Pipes force into separate lines with quoted fields in PHP associative array format: "attribute_name1"=>"value","attribute_name2"=>...
