php Mod rewrite test
In the directory where you plan to install Elgg, do the following:
Create the file .htaccess and add these two lines
RewriteEngine on
RewriteRule ^testing.php$ modrewrite.php
This tells the webserver to load modrewrite.php when testing.php is
requested.
In order to get this test to work on some virtual servers, you
may need to add:
RewriteBase /
prior to the RewriteRule line.
Create the file modrewrite.php with this line
<?php echo "mod_rewrite works"; ?>
Create the file testing.php with this line
<?php echo "mod_rewrite does not work"; ?>
Now use your web browser to load testing.php. The text that shows will
tell you whether mod_rewrite is working

和本地并发
。
先说一下网络请求并发
理论描述
假设有一个client，程序逻辑是要请求三个不同的server，处理各自的响应。传统模型当然是顺序执行，先发送第一个请求，等待收到响应数据后再发送第二个请求，以此类推。就像是单核CPU，一次只能� ......
如果你使用一面大镜子作为冲浪板会发生什么？或许你会在较短的时间内征服海浪，但是你肯定从内心深处明白，这不是冲浪的正确选择。同样的道理也适用于PHP编程，尽管这样的类比听起来有一些古怪。我们经常听到有人试图用一个周末多点的时间来学会PHP，但是请恕我直言，这是学习这门编程语言的一种非常糟糕的方式。
