Removing last comma in PHP?

Question

I have this PHP code:

foreach( $wpdb->get_results(
) as $key => $row) {

echo \"[\'\". $row->DATE . \"\',\". $row->total_sales . \"],\";

}
         


        

Answer 1

put your string in substr() function

$string = "";
while ($row = mysql_fetch_array($result)) {
  $string .= $name . ', ';
}
echo substr($string, 0, strlen($string) - 2);
