Implementing updates in shell scripts Php5_linux shell

I'm obsessed with the Shell, and I like to watch the characters jump in the Black Console interface, and strangely, I didn't become a Linux/unix programmer, but just a bad egg to write a CGI program. What do people call "PHP programmers"? Right--grassroots ~ Well, buried in the soil too long, maybe one day will rot off!

may be spoiled by Windows, really do not want to change the OS, fortunately there are cygwin,mingw ... Things like that, when appropriate, you can take out to install the B, self comfort ~

I always like to download the latest snapshot from windows.php.net, not that I want to experience the latest features, but the relationship between obsessive-compulsive disorder-,-。 All the software on my machine, the program is up to date, most of them still have beta tags, even some of them are directly from the svn,git to drag down the trunk version, think really sick. If you climb these sites every day, human flesh check whether there is a new version of the release, so as to meet their abnormal psychology, it is really crazy.

If you can get the machine to do something, don't do it by hand. The following code will automatically check the latest snapshot and unzip to the directory you want. And then what? Set up a cron job to hang up, you can find a new fun ~

The Code downloads the None thead safe VC9 version, with a note to replace it with a version that is available to you. If you need to force an update, add the "–force" argument.

The last line uses ICACLS to reset the permissions on the files in the Php5-nts directory (note that the path is written, ICACLS is Windows own program), because Cygwin will make NTFS permissions a huge nausea.
PS: Non-cgi/fcgi installation mode, remember to turn off the Web Server.
