number_format() causes error "A non well formed numeric value encountered"
I am using number_format to round floats to only 2 decimal digits. The problem is that some of my inputs don't have more than 2 decimals dig开发者_如何学Goits to begin with. So the code:
number_format($value, 2)
Instead of peacefully adding 0 in case it doesn't have enough decimal digits, it raises errors inside Apache log and that's not desirable.
So number_format(2.1, 2)
or number_format(0, 2)
will raise error in Apache log.

How to fix this?
Try type casting first parameter of number_format() to float:
$format = number_format((float)0, 2);
or
$format = number_format(floatval(0), 2);
Try to replace decimal point and after that cast to float.
var_dump((float)number_format((float)str_replace(",", ".", "20,5"), 2, ".", ""));
result: float(20.5);
Without replacing:
var_dump((float)number_format(floatval("20,5"), 2, ".", ""));
result: float(20);
var_dump((float)number_format((float) "20,5", 2, ".", ""));
result: float(20);
When doing calculations, use
number_format($value, 2, ".", "")
And if you would like to display numbers with .00 at the end (like "50.50" not "50.5") then you would use
numer_format($value, 2)
I used this:
str_replace(array(".", ","), array(",", "."), $value)
Maybe it'll help someone out.
Function is recognizing it as a string.
Convert to number by adding zero:
number_format($NUMBER+0)
