Question

I have little confusion in foreach loop.

There is a foreach in my below code:

foreach ($myrows as $rows){
    $option = $rows->option_value;
    $option_value = recursive_unserialize_replace($site_url,$_POST['url_name'],$option);
    $sql.= '('."'".$rows->option_name."'".','."'".$option_value."'".','."'".$rows->autoload."'".')'.",";
}

Look at the line number 3. There is a comma I used to print. Now I do not want to print the comma in the last line.

Answer 1

Try this:

$array = array();

foreach ($myrows as $rows){
   $option = $rows->option_value;
   $option_value = recursive_unserialize_replace($site_url,$_POST['url_name'],$option);
   $array[] = '('."'".$rows->option_name."'".','."'".$option_value."'".','."'".$rows->autoload."'".')';
}

$sql = join(', ', $array);
