如何在PHP中的数字之间插入连字符？

Question

I want to make a script in PHP which displays the numbers and a hyphen between the numbers. It should look like this:

1-2-3-4-5-6-7-8-9-10

I have the following script right now, but the problem is it displays a hyphen at the end of the numbers:

$x = 1;
$h = 1;
while($x <= 10) {
    echo "$x";
    $x++;

    if($h < $x){
        echo "-";
        $h++;                
    }
}

Thanks in advance :)

There is simpler way to do this work. Use range() to create array contain numbers and use implode() to join target array with string.

echo implode("-", range(1, 10));
