添加for循环的所有结果并回显它

Question

So I have this code:

<?php
for ($x=1; $x<=1000; $x++)
{

    if ($x % 15 == 0 || $x % 26 == 0)
    {
        echo $x;
        echo "<br \>";
    }
}
?>

This code will output all numbers divisible by 15 or 26. But what I really want is to add up all the results and echo it. So what's the best way to achieve this?

Answer 1

<?php
$sum = 0;
for ($x=1; $x<=1000; $x++)
{
    if ($x % 15 == 0 || $x % 26 == 0)
    {
        $sum += $x;
        // echo $x;
        // echo "<br \>";
    }
}
echo $sum. "<br\>";
?>
