PHP - 打印多维数组

I'm having a brain-block with this piece of code. I want to print a multidimensional array in PHP where the 'columns' are separated by hyphens and the 'rows' are separated by newlines.

My problem is that my code prints a '-' at the end of each row. This is obvious when looking at my code:

N.B. ($result is a 2D array i.e. $result[][])

foreach($result as $row){
    foreach($row as $column){
            echo $column . "-";
    }
    echo "
";
}

This is the output:

42-1-1394752507-16.125-
43-1-1394752569-16.125-
44-1-1394752632-16.562-
45-1-1394752693-17.125-

What is the best way to print this out to avoid the trailing - on each row? I could do a check to see if the current $column is the last element in the $row but I don't actually know how to do this

    implode is your friend:

    foreach($result as $row){
        echo implode('-', $row) . "
    ";
    }
