I see over 3000 posts on this site when I search for [remove last comma](https://stackoverflow.com/search?q=remove+last+comma). This is a fairly common programming issue which should be easy to track down with some searching. — Josh, Dec 05 '17 at 04:01

<?php 
for( $x=1 ; $x<=10 ; $x++){
echo "$x";
if($x!=10)
echo ",";
}
?>

Check for the last iteration and avoid ','

You can remove the last comma using join.

echo join(',', range(1,10));
