调用eval时，出现如下错误：
Fatal error: Maximum execution time of 30 seconds exceeded in d:\phparticle\sort.php on line 199

Fatal error: Maximum execution time of 30 seconds exceeded in d:\phparticle\admin\class\session.php on line 26

Warning: Unknown(): A session is active. You cannot change the session module's ini settings at this time. in Unknown on line 0


错误部分代码：
$qu=$DB->query("SELECT * FROM user_".$sortinfo[fileds]."");
while($sortdate=$DB->fetch_array($qu)){
for ($j=1;$j<=$i;$j=$j++) {
$sortdateshow=$sortdate[$filed[$j]];
eval("\$sort_anothor .= \"" . gettemplate('sort_anothor') . "\";");
}

}
