I'm building a page to pull some statistics on several (43 actually) mailboxes by connecting to their imap server and requesting the all headers in the inbox (using imap_headers ($mbox)). Though, really, all I'm trying to get is the number of unread/unseen pieces of mail and the date sent of the oldest piece.

The problem is that the imap_headers function seems to timeout on several email user boxes. Always this error is "Fatal Error: Maximum execution time of 120 seconds exceeded."

The first question is how do I handle that error gracefully, and continue on with other operations (like moving on to another page/iteration of the loop)?

Secondly, if anyone has a better way of doing this, Please, I'm begging for suggestions. The Jhereg

I'm building a reputation for honesty so I can blow it when something big comes along... This ain't it.
 
A bump and more information:

I've designed an error handler to capture this error and move on, but unfortunately, it too suffers from the time exceeded.

What I'm now looking for is a way to catch this errror before it brings the site to a dead stop.

Here's the code:

Code:
// Code generating the error.
set_time_limit(120) ;
$headersThing =  imap_headers ($mbox);

Error handler:
Code:
// set the error reporting level for this script
error_reporting (E_ERROR  | E_CORE_ERROR  | E_WARNING | E_CORE_WARNING | E_PARSE );

// error handler function
function myErrorHandler ($errno, $errstr, $errfile, $errline) {
	set_time_limit(0) ;
  switch ($errno) {
  case E_CORE_ERROR:
  case E_ERROR:
    echo &quot;HI Everyone: <b>FATAL</b> [$errno] $errstr<br>\n&quot;;
    echo &quot;  Fatal error in line &quot;.$errline.&quot; of file &quot;.$errfile;
    echo &quot;, PHP &quot;.PHP_VERSION.&quot; (&quot;.PHP_OS.&quot;)<br>\n&quot;;
    echo &quot;Aborting...<br>\n&quot;;
    exit -1;
    break;
  case E_WARNING:
  case E_CORE_WARNING:
    echo &quot;HI Everyone: <b>ERROR</b> [$errno] $errstr<br>\n&quot;;
    break;
  case E_PARSE:
    echo &quot;HI Everyone: <b>WARNING</b> [$errno] $errstr<br>\n&quot;;
    break;
  case E_NOTICE:
  		break; 
  default:
    echo &quot;Unkown error type: [$errno] $errstr<br>\n&quot;;
    break;
  }
}

$old_error_handler = set_error_handler(&quot;myErrorHandler&quot;);

I would think this would work, however it generates more execution time errors.

Output:

Code:
Fatal error: Maximum execution time of 120 seconds exceeded in C:\Inetpub\[URL unfurl="true"]wwwroot\imap\USBoxes\boxloop.php[/URL] on line 33

Fatal error: Maximum execution time of 120 seconds exceeded in C:\Inetpub\[URL unfurl="true"]wwwroot\imap\include\errors.php[/URL] on line 8

Line 33 is the imap_headers call from above, and line 8 is
Code:
function myErrorHandler ($errno, $errstr, $errfile, $errline) {
Anyone know of a way to make the error handler function correctly, instead of generating the error when it's called? The Jhereg
