PHP在哪里保留软件版本？ [关闭]

Question

All,

Where can I keep my software version in a PHP web application? I inherited an application that has versions in about 500 different files (for example it might say "Super Program v1.0 written by blah blah" at the bottom of each page, and I have to change it to 2.0, so whenever I need to update the version, I use Eclipse's search function and go to town. Globals seem the right place, but then I find that my variable doesn't get propagated unless the .PHP file is included, etc.. Any ideas?

Edit: I'm also open to any tools that are used to help me handle this, I haven't tried using any outside utilities or eclipse extensions to swap out the variables, I'm trying to get an idea for what everyone else is doing.

Thanks, Dan Chase

Use, Subversion, GIT or something similar for a start. This will automatically track versions meaningfully so you can go back and forward through versions with confidence. This is a really good practice to get into, especially with 500 files to work with.

To add the revision number into code, first replace all references with a constant. Then use a build tool like phing, ant or similar to obtain the latest revision number from the repository and assign it to the constant in a config file.

This means that the revision name displayed by you code always refers back to an easily obtainable version of the code at any time.

If you use something like Git which does not have incremental revision numbers, you can work around it by using tagging with appropriate names and putting the tag name into the constant which is displayed instead.
