remove trailing comma

[vinasite]

hi,

I wrote a script that generate a list of words separate by a comma, and the number of words is different each time. Sometimes it there's 1 word, and sometimes there's more.

When there's only one word, it'll display "word,"
and when there's more than one words, it'll display "word1,word2,word3,".

My question is how can i trim the trailing comma so that if there's no more words left, the comma wont show up?

Thank you

Use an if statement before you print out.
Pseudocode:

if <at the end of array>
print out the element only
else
print out the element and the comma

Is that clear?

Son,

That didnt help much since i'm still pretty new ;o(

here's the code i used:

	$brand[0] = $chk_canon;
	$brand[1] = $chk_ricoh;
	$brand[2] = $chk_minolta;
	$brand[3] = $chk_sharp;
	$brand[4] = $chk_xerox;
	$brand[5] = $chk_toshiba;
	$brand[6] = $chk_mita;
	$brand[7] = $chk_lanier;
	$brand[8] = $chk_riso;
	$brand[9] = $chk_gestetner;
	for($i=0; $i<10; $i++){
	 if($brand[$i]){
		  $whichbrand="$brand[$i], $whichbrand";
		}
	}

notice the comma after $brand[$i]

No problem, here people are very helpful!

	$brand[0] = $chk_canon;
	$brand[1] = $chk_ricoh;
	$brand[2] = $chk_minolta;
	$brand[3] = $chk_sharp;
	$brand[4] = $chk_xerox;
	$brand[5] = $chk_toshiba;
	$brand[6] = $chk_mita;
	$brand[7] = $chk_lanier;
	$brand[8] = $chk_riso;
	$brand[9] = $chk_gestetner;
	for($i=0; $i<10; $i++){
	 if($brand[$i])
         {
           if ($i != 9) // NOT at the end of array
           { $whichbrand .="$brand[$i],"; }
           else 
           { $whichbrand .="$brand[$i]";}
         }
	}
