Dagorlad Posted October 27, 2006 Share Posted October 27, 2006 I see this often in open source scripts, but am at a loss to understand what it is for or how it is used:/* $Id: page_header.php,v 1.106.2.25 2005/10/30 15:17:14 acydburn Exp $*/Can someone explain its purpose please? Many thanks. Link to comment https://forums.phpfreaks.com/topic/25264-would-like-to-understand-what-id-and-exp-are-all-about/ Share on other sites More sharing options...
btherl Posted October 27, 2006 Share Posted October 27, 2006 This is used by various version control systems, such as CVS, RCS and SVN. It tells you what version of the file you have, when it was last updated, and who did the update (acydburn updated that file most recently).It's very useful information for developers, since it helps them keep track of code changes, and let's them know exactly which version of the code they are looking at.

Dagorlad Posted October 28, 2006 Author Share Posted October 28, 2006 Thank you both for the help. I had assumed it was some kind of version control system, since the filename, version, date and author were all listed in the expression, but I was unable to see how it would work.It makes perfect sense now. Thanks again. Link to comment https://forums.phpfreaks.com/topic/25264-would-like-to-understand-what-id-and-exp-are-all-about/#findComment-115796 Share on other sites More sharing options...
