"how to strip trailing zeros in php" Answer’s


Forget all the rtrims, and regular expressions, coordinates are floats and should be treated as floats, just prepend the variable with (float) to cast it from a string to a float:

$string = "37.422005000000000000000000000000";
echo (float)$string;



The actual result you have are floats but passed to you as strings due to the HTTP Protocol, it's good to turn them back into thier natural form to do calculations etc on.
