implode explode in php -

-

this code-

$row=mysql_fetch_array($sql1);    echo $days= $row['attending_days'];   echo $days1 = explode($days',');   echo count($days1);

it show me 1 value

use this

while($row=mysql_fetch_array($sql1)){    $days= $row['attending_days'];    $days1 = explode(',' , trim($days));    echo count($days1); }

why using echo lines?
