Formatting echo from array

[shamuraq]

Hi, I have an array that i want to 'echo' in a foreach loop:

foreach($numbers as $num){
    echo $num.':';
}

i need the output to be 459:534:141 instead of 459:534:141:. How do i remove the ':' at the final loop?

Thanx in advance.

Use join() instead of the foreach loop.

echo join(':', $numbers);
