From: quentin389 at gmail dot com Operating system: Linux PHP version: Irrelevant Package: Unknown/Other Function Bug Type: Bug Bug description:get_browser() incorrectly parsers entries with "+" sign.
Description: ------------ get_browser() incorrectly handles entries from browscap.ini files when they have "+" sign in the pattern match. The "+" in the ini files is a LITERAL character, not a wildcard match. The only wildcard that browscap.ini source files use are "*" and "?". The result of that is that none of the browscap.ini entries that have a match pattern with "+" ever match the browsers that they are supposed to match. My suspicion is that if you'd change https://github.com/php/php-src/blob/master/ext/standard/browscap.c#L110 and add: case '+': t[j++] = '\\'; t[j] = '+'; break; everything would be fixed. But I haven't tested that. Test script: --------------- // browscap.ini entry: // [Mozilla/5.0 (compatible; AhrefsBot/*; +http://ahrefs.com/robot/)] // Parent="Search Engines" // Browser="AhrefsBot" echo "<pre>"; var_dump(get_browser('Mozilla/5.0 (compatible; AhrefsBot/4.0; +http://ahrefs.com/robot/)')); Expected result: ---------------- object(stdClass)#2 (35) { (...) ["Browser"]=> string(9) "AhrefsBot" Actual result: -------------- object(stdClass)#1 (34) { (...) ["browser"]=> string(15) "Default Browser" -- Edit bug report at https://bugs.php.net/bug.php?id=65550&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=65550&r=trysnapshot54 Try a snapshot (PHP 5.3): https://bugs.php.net/fix.php?id=65550&r=trysnapshot53 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=65550&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=65550&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=65550&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=65550&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=65550&r=needscript Try newer version: https://bugs.php.net/fix.php?id=65550&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=65550&r=support Expected behavior: https://bugs.php.net/fix.php?id=65550&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=65550&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=65550&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=65550&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=65550&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=65550&r=dst IIS Stability: https://bugs.php.net/fix.php?id=65550&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=65550&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=65550&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=65550&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=65550&r=mysqlcfg
