Question

我正在使用带有PHP和MYSQL的libcharts并且它工作正常但是当我在我的代码中使用datetime选择器时它会显示

Fatal error: Maximum execution time of 30 seconds exceeded in C:\xampp\htdocs\xampp\libchart\libchart\classes\view\text\Text.php on line 91.

有时会显示图表，大多数时候会出现此错误。

我更改了max-execution-time=100中的php.ini，但仍然无效。请任何人告诉我解决方案。

这是我的代码：

  mysql_connect ($dhost,$uname,$pword) or die (mysql_error());
  mysql_select_db($dbase) or die (mysql_error());

$chart = new VerticalBarChart(580, 600);

$dataSet = new XYDataSet();
//$to = isset($_REQUEST["to"]) ? $_REQUEST["to"] : "";
//$from = isset($_REQUEST["from"]) ? $_REQUEST["from"] : "";

   if(isset($_REQUEST['to'])){ $to = $_REQUEST['to'];
   if(isset($_REQUEST['from'])){ $from = $_REQUEST['from'];    
  //query all records from the database
  $data = mysql_query("SELECT department, COUNT(visitId) AS visitId FROM visit WHERE CAST(VisitDate AS DATE) BETWEEN '$to' AND '$from' GROUP BY department")
or die(mysql_error());


  //execute the query
  $result = mysql_query($data);



  while ($row = mysql_fetch_assoc($data))
    {
        extract($row);
        $dataSet->addPoint(new Point("$department", $visitId));
    }

    //finalize dataset
    $chart->setDataSet($dataSet);


$chart->setTitle("Total patients(Department)");
$chart->render("generated/bb.png"); 
    }}
    ?>

在查询之前使用set_time_limit(50)来增加默认执行时间

执行时间致命错误
