$arr = array(2.1,3.1);
if(in_array(2.1000,$arr))
echo "yes";
else
echo "no";
I want it should show “No” but it ignores 0’s after decimal point.
What you can do is
(string)$arr[0] == '2.1000'. The only problem is that when using a floating number in PHP it’s going to “remove” the leading and trailing zeros, therefore they are always going not to be zeros unless you store them as strings initially or if you keep track of the leading and trailing zeros in another array.
