Question

I am running this script it is fine for one context but when I try this on 4 recipients it is not working just showing this error:

Fatal error: Maximum execution time of 30 seconds exceeded in D:\Hosting\8011955\html\admin\newsletter.php on line 60

How can I improve this code? I just want to send email not more than 200.

here is the code:

if(!(is_array($errors)))
{
$headers = "MIME-Version: 1.0" . "\r\n";
$headers .= "Content-type:text/html;charset=iso-8859-1" . "\r\n";
$headers .= "From: \"".$from_name."\" <".$from_email.">\n";

    $query="SELECT email From newsletter WHERE visible='1'";
    $result=mysql_query($query) or mysql_error();
    while($rowdata=mysql_fetch_array($result))
    {
       $headers .= "To: \"".$to_name."\" <".$rowdata['email'].">\n";    
           mail($rowdata['email'], "$sub",$message, $headers);
    }   
}

By default, PHP scripts run for 30 seconds and then stop. This value is controlled by the max_execution_time value in php.ini. You can override this value within the current script by calling the set_time_limit() function. Each time you call set_time_limit() the script execution timer starts over at zero. So you can put it inside of your while {} loop to give your script as much time as it needs.

while($rowdata=mysql_fetch_array($result))
{
   set_time_limit(30); // Reset script timer and give script 30 seconds to send the next email
   $headers .= "To: \"".$to_name."\" <".$rowdata['email'].">\n";    
   mail($rowdata['email'], "$sub",$message, $headers);
}
