PHP MySQL小查询超时，必须将限制设置为10

在调用mysql_query()进行相对较小的查询时，我收到了PHP超时错误，因此我必须将限制设置为10.

I am getting PHP timeout errors when calling mysql_query() for a relatively small query, so i have to set the limit to 10.

Fatal error: Maximum execution time of 120 seconds exceeded in C:\xampp\htdocs\data.php on line 19

我已经从代码中删除了循环，代码似乎挂在了mysql_query()函数上.

I have removed the loop from the code, the code seems to hang at the mysql_query() function..

mysql_connect("192.168.50.250",$username,$password);
@mysql_select_db($database) or die( "Unable to select database");
$query = "SELECT T.Tag as 'Device', y.alarmdesc as 'AlarmType', a.Active, a.Cleared FROM gencore.gc_alarms a JOIN ist.Tree T ON(T.DeviceId = a.DeviceId)  JOIN GenCore.gc_alarmtypes y ON (a.alarmType = y.aid) LIMIT 10";

$result=mysql_query($query);

$num=mysql_numrows($result);

mysql_close();
?>
<table class="sortable resizable editable tableStyle2">
<tr class="headerStyle">
<th>Device</th>
<th>AlarmType</th>
</tr>
<?php
 $i=0;
while ($i < $num) 
{

    $f1=mysql_result($result,$i,"Device");
    $f2=mysql_result($result,$i,"AlarmType");

?>

<tr>
<td><?php echo $f1; ?></td>
<td><?php echo $f2; ?></td>

</tr>

<?php
    $i++;
} 
?>

</body>
</html>

查询从其他任何地方执行都非常快，只有340行，有人 任何指针如何从数据库中检索小表?

The query executes very quick from anywhere else, and is only 340 rows, does anyone have any pointers how to retrieve the small table from the DB?
