--------------------[snip]--------------------
PHP times the time that the script itself needs to execute, neglecting any
external resources, be it database access, or e.g. fetching pages from
other servers.
For example, fetching a page from, say, www.ibm.com (I chose this because
of its lengthy load time here in Europe), one pass needs approx. 5 seconds
(including the page fetch of course). Looping this script will run much
longer than 30 secs time limit, because time is consumed outside the
current script.
OTOH, running an endless loop not doing anything outside, e.g. just
incrementing a number, will terminate after quite precisely 30 secs - all
the time is consumed _within_ the script.
For lengthy import/export routines I usually resort to doing 5-10 records
in one pass (or more, that depends of course), then sending
echo '<script>document.location.href="' . $_SERVER['PHP_SELF'] . '?' .
SID . '";</script>';
exit;
using sessions to store the current import location and status.
HTH and clears things up,
