#50267 [Opn]: get_browser with null parameter runs on empty user agent string

ID: 50267 User updated by: nachumk at gmail dot com Reported By: nachumk at gmail dot com Status: Open Bug Type: Unknown/Other Function Operating System: Windows XP 32 bit PHP Version: 5.3.1 New Comment: I am running Apache 2.2.14 (apache_2.2.14-win32-x86-openssl-0.9.8k.msi), PHP 5.3.1 (php-5.3.1-Win32-VC9-x86.msi (both as module and cgi), and php-5.3.1-nts-Win32-VC9-x86.msi), on Windows XP 32 bit. It works when I run PHP 5.2.11. Previous Comments: ------------------------------------------------------------------------ [2009-11-23 05:18:19] nachumk at gmail dot com Description: ------------ get_browser should work with null string and doesn't when using 5.3.1. 5.2.11 works fine. Reproduce code: --------------- <?php phpinfo(); echo "User Agent: " . $_SERVER['HTTP_USER_AGENT'] . "<br>"; echo 'print_r(get_browser($_SERVER[\'HTTP_USER_AGENT\'], true));<br>'; print_r(get_browser($_SERVER['HTTP_USER_AGENT'], true)); echo '<br>print_r(get_browser(null, true))<br>'; print_r(get_browser(null, true)); ?> Expected result: ---------------- That both get_browser calls should produce identical results. Actual result: -------------- The first call with $_SERVER['HTTP_USER_AGENT'] returns proper results and the call with null returns a default response (same as what it would return with a completely empty user agent string). ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=50267&edit=1
