I have this code throwing up the error:
<?php
$val1 = $totalsum;
$res = ( $val1 / $val2) * 100;
$val2 = count($allcontent);
$res = ( $val1 / $val2) * 100;
// 1 digit after the decimal point
$res = round($res, 1); // 66.7
echo "Success: ";
echo $res;
echo "%";
?>
I have tried adding this line:
if ($res === 0)
{
echo "not eligible";
}
but it still gives the error. any ideas?
You'd want to check $val2 before the division occurs:
<?php
$val1 = $totalsum;
$val2 = count($allcontent);
if($val2 != 0)
{
$res = ( $val1 / $val2) * 100;
// 1 digit after the decimal point
$res = round($res, 1); // 66.7
echo "Success: ".$res."%";
}
else
{
echo "Count of allcount was 0";
}
?>
