Sometimes we write a logic to show comma separated data. But the challenge is not to append comma to the last value.
We can do this by using next() function:
<?php
$arr = array('tvs','hero','honda','bajaj');
$copy = $arr;
foreach ($arr as $val) {
echo $val;
if (next($copy )) {
echo ','; // Add comma for all elements instead of last
}
}
?>
