format a number

ok, I have tried floor and number_format but each wants to round. I don't want to round the number.

Example: 28.955875 should be 28.95 I don't want 28.96

language is PHP.

There is never a good, generalized solution, when you want PHP to give you what amounts to the "wrong" answer with numbers.  This works, given the test data, but I would not want to depend on it.

$float = 28.955875;

$numbr = substr("$float",0,5);

var_dump($float, $numbr);

No matter the number, even if it's 128.955875 or 3428.955875 and so on this will just format to 2 unrounded decimal places and not just grab the first 5 characters.

$thenumber = 28.955875;
echo number_format(floor($thenumber *100)/100, 2);
