<simpara>
If the <link linkend="ini.track-errors"><option>track_errors</option></link>
feature is enabled, any error message generated by the expression
will be saved in the variable
<varname>$php_errormsg</varname>.
This variable will be overwritten on each error, so check early if you
want to use it.
Any error message generated by the expression is available in the <literal>"message"</literal>
element of the array returned by <function>get_error_last</function>.
The result of that function will change on each error, so it needs to be checked early.
