PHP round to integer

Question

I want to round a number and I need a proper integer because I want to use it as an array key. The first \"solution\" that comes to mind is:

$key = (int)roun         


        

Answer 1

For My Case, I have to make whole number by float or decimal type number. By these way i solved my problem. Hope It works For You.

$value1 = "46.2";
$value2 = "46.8";


// If we print by round()
echo round( $value1 );    //return float 46.0
echo round( $value2 );    //return float 47.0


// To Get the integer value
echo intval(round( $value1 ));   // return int 46
echo intval(round( $value2 ));   // return int 47
