|
|
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
|
|
<literal>max_execution_time</literal> value defined in the <link
|
|
linkend="ini.max-execution-time">configuration file</link>. If
|
|
seconds is set to zero, no time limit is imposed.
|
|
</simpara>
|
|
<simpara>
|
|
When called, <function>set_time_limit</function> 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.
|
|
</simpara>
|
|
<simpara>
|
|
<function>set_time_limit</function> has no effect when PHP is
|
|
running in safe mode. There is no workaround other than turning
|
|
off safe mode or changing the time limit in the <link
|
|
linkend="ini.max-execution-time">configuration file</link>.
|
|
</simpara>
|
|
<note>
|
|
<para>
|
|
The <function>set_time_limit</function> function and the
|
|
configuration directive <link
|
|
linkend="ini.max-execution-time">max_execution_time</link> only
|
|
affect the execution time of the script itself. Any time spent
|
|
on activity that happens outside the execution of the script
|
|
such as system calls using <function>system</function>, the
|
|
<function>sleep</function> function, database queries, etc. is
|
|
not included when determining the maximum time that the script
|
|
has been running.
