Doc #75805 [NEW]: Documentation should clarify behavior of version_compare when there are spaces

From: ksours at internetbrands dot com Operating system: PHP version: Irrelevant Package: Documentation problem Bug Type: Documentation Problem Bug description:Documentation should clarify behavior of version_compare when there are spaces Description: ------------ I'm not 100% sure if this is a documentation problem or a code problem but the documentation doesn't quite match the behavior so one of them is wrong. Since the function behavior isn't clearly wrong I'm going with doc. On "version_compare" it says: "Then it compares the parts starting from left to right. If a part contains special version strings these are handled in the following order: any string not found in this list < dev < alpha = a < beta = b < RC = rc < # < pl = p." If there is a space in the version string this gets incorporated into the "special string" and thus the string will always fall under "any string not found in this list" even if it appears to match. You can work this out from the transformations described but it's *not* intuitive and should be explicitly called out (or the function behavior changed to handle spaces) Test script: --------------- //these will all return "equal" results which is not what is immediately expected var_dump(version_compare('1.0.0 alpha 1', '1.0.0 beta 1')); var_dump(version_compare('1.0.0 dev 1', '1.0.0 beta 1')); var_dump(version_compare('1.0.0 totalgarbage 1', '1.0.0 beta 1')); -- Edit bug report at https://bugs.php.net/bug.php?id=75805&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=75805&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=75805&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=75805&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=75805&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=75805&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=75805&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=75805&r=needscript Try newer version: https://bugs.php.net/fix.php?id=75805&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=75805&r=support Expected behavior: https://bugs.php.net/fix.php?id=75805&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=75805&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=75805&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=75805&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=75805&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=75805&r=dst IIS Stability: https://bugs.php.net/fix.php?id=75805&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=75805&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=75805&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=75805&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=75805&r=mysqlcfg
