PHP Question

how to implement calculation of percents:

`$x=3;`

$y = 100\$x; // 3.333..

$x*$y - and here I need to get 100 without Observational error

Any ideas?

Answer Source

Your backslash is not a division symbol. You must use division `/`

symbol. Here's an example using `number_format()`

to round to the hundredths position.

```
$x = 3;
$y = 15;
$percent = $x/$y;
$percent_friendly = number_format( $percent * 100, 2 ) . '%';
```
