php set_time_limit(0) 设置程序执行时间的函数
一个简单的例子,在网页里显示1500条语句,如果未设置失效时间,则程序执行到791时结束了,如果把 set_time_limit(0); 前的注释符//去除,则程序直到1才结束。
set_time_limit(0);
括号里边的数字是执行时间,如果为零说明永久执行直到程序结束,如果为大于零的数字,则不管程序是否执行完成,到了设定的秒数,程序结束。
一个简单的例子,在网页里显示1500条语句,如果未设置失效时间,则程序执行到791时结束了,如果把 set_time_limit(0); 前的注释符//去除,则程序直到1才结束。
代码如下:
//set_time_limit(0);
$i=1500;
include ("inc/conn.php");
while($i>0)
{
$sql="INSERT INTO php (php)
VALUES ('$i')";
if ($conn->execute($sql)===flase)
{
//echo "数据插入错误".$conn->errormsg();
}
else
{
$phpid=$conn->Insert_ID();
echo $i."已经存入数据库,编号:".$phpid;
}
$i--;
echo "
";
}
?>
