> Set the number of seconds a script is allowed to run. If this is
reached, the script returns a fatal error. The default limit is
30 seconds or, if it exists, the max_execution_time value defined
in the <A

file</A
>. If seconds is set to zero, no time limit is
imposed.

> When called, <B
CLASS="function"
>set_time_limit()</B
> restarts the
timeout counter from zero. In other words, if the timeout is the
default 30 seconds, and 25 seconds into script execution a call
such as set_time_limit(20) is made, the script will run for a
total of 45 seconds before timing out.

PHP is running in safe mode. There is no workaround other than
turning off safe mode or changing the time limit in the <A
