PHP / CodeIgniter - Iterating through 9000+ DB rows generates a download of blank page

I'm trying this:

function send_sms() {
 $liveQuery = $this->db->get('liveList');
 $counter = 0;

 foreach($liveQuery->result() as $row):
  $counter = $counter+1;
  echo("Not hatin', just iteratin'. Message " . $counter);
 endforeach;
}

When liveList has 8000 records it runs just fine, but when I try with 9000 rows it generates a download of开发者_StackOverflow中文版 a blank, 0 KB, document. Anyone know why this happens?

I am not familiar with codeigniter, but do you have php error reporting on? There could be an error being thrown that's hidden.

Blank pages are normally a symptom of time-outs or crashed scripts. You might be able to find the exact reason in the server logs. Make sure you have the log_errors directive enabled in your PHP installation. Also, have a look at the web server logs.
