even know what numbers are or how to add them together. In fact, as it turns out, I did not attend the consortium, but instead was lost on a highway in the middle of the desert. I thought the directions said "take 7th Avenue to 34th Street," and - thinking I was to add them together - wound up 1,239 miles away. [That'll teach me to even bother trying today. All work and no sleep makes Danny an idiot.] git-svn-id: https://svn.php.net/repository/phpdoc/en/trunk@289304 c90b9560-bf6c-de11-be94-00142212c4b1

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
|
|
&php.ini;.
|
|
</para>
|
|
<para>
|
|
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
|
|
<literal>set_time_limit(20)</literal> is made, the script will run for a
|
|
total of 45 seconds before timing out.

This function has no effect when PHP is running in &safemode;. There is
|
|
no workaround other than turning off safe mode or changing the time limit
|
|
in the &php.ini;.

<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>, stream operations, database
|
|
queries, etc. is not included when determining the maximum time that the
|
|
script has been running.
|
|
This is not true on Windows where the measured time is real.
