请问。。CI的timer怎样用的。。求教程。求思路
大家好。真不好意思。。用CI真的不长时间。。现在还在用1.7.2。。我php是自学的。。还不是太懂。。只懂做一般的小网站。。小功能。。调用一下API。。
小弟我在这很想求CI的timer的教程。。当然我自己也会看相关的资料。。本来不是饭来张口的人。。
不过小弟我真的找不到资料。。自己看源代码。。也有很多不明的地方。。CI的强大。。
很多机制同java相同。。不过写法真的差天共地。。教程不用写得太明白的。。给我个思路就好了。。谢谢 php里没有timer的东西，要么用循环+sleep来模拟，要么利用linux的crontab（PHP需要在cgi模式下） jeongee 发表于 2011-10-14 11:35 static/image/common/back.gif

$BM->mark('total_execution_time_start');

这个CI入边的不是定时器吗!? jeongee 发表于 2011-10-14 11:35 static/image/common/back.gif

我看一下在CI 中的controllor中 循环+sleep来模拟 能不能做吧。。好的。。谢谢 rain16881 发表于 2011-10-14 11:45 static/image/common/back.gif

这个不是定时器
这个是计时器，记录执行一个操作用了多长时间，一般用来性能调试的。 baiyuxiong 发表于 2011-10-14 11:56 static/image/common/back.gif

好的。。谢谢。。如果这个不是定时器。。我就不在向这个方向去找资料了。。我再找找相关php的定时器的资料吧。。 rain16881 发表于 2011-10-14 12:02 static/image/common/back.gif

你要定时器做什么？
什么需求？ baiyuxiong 发表于 2011-10-14 13:31 static/image/common/back.gif
你要定时器做什么？
什么需求？
就最简单的。。可以在后台运行。。关了php页也可以运行。。有开关。。

这个你了解下PHP的后台进程的实现吧 可以用电脑的事务日志来处理呀
建立bat文件
在事务日志里面设置调用
如：
E:\xampp\php\php.exe -q E:\www\sendmail\index.php
上面的bat代码你应该能看懂
以前用过
