Is there a way with number_format() to leave out decimal places if the number is not a float/decimal?
For example, I would like the following input/output combos:
50.8 => 50.8 50.23 => 50.23 50.0 => 50 50.00 => 50 50 => 50
Is there a way to do this with just a standard number_format()?

You can add 0 to the formatted string. It will remove trailing zeros.
echo number_format(3.0, 1, ".", "") + 0; // 3
A Better Solution: The above solution fails to work for specific locales. So in that case, you can just type cast the number to float data type. Note: You might loose precision after type casting to float, bigger the number, more the chances of truncating the number.
echo (float) 3.0; // 3
Ultimate Solution: The only safe way is to use regex:
echo preg_replace("/.?0+$/", "", 3.0); // 3
echo preg_replace("/d+.?d*(.?0+)/", "", 3.0); // 3
