Multiply a character string by a number

Question

I want to display a fraction in PHP. For that I wrote:

$a = 3; 

$b = 2;

$c = \"$a/$b\";

echo $c; // this displays 3/2
but on the other hand I want to multipl         


        

Answer 1

Try change single quotes into double quotes. Of without quotes, depend what you expect. Then try change type of $c.

Example:

$a = 3;
$b = 2;
$c = "$a/$b"; // or $c = $a/$b;
echo $c; // this displays 3/2
// but on the other hand I want to multiply $c by an integer;
echo (float)$c * 2; // this shows me an error
