How to convert float percent number value to integer percent number value in PHP?

Example: 3.8461538461538 % = 4 %

Update: 
Here is my code , I coded to get percent value, but I get decimal value, but I need it without decimal value.

```
$total = array_sum($total_count);
$percent = ($occurs/$total)*100;
echo $percent ; 
echo "%";

```
