#22132 [Fbk->Opn]: getcwd() returns the wrong cwd in output handler function

ID: 22132 User updated by: adam@adammckaig.com Reported By: adam@adammckaig.com -Status: Feedback +Status: Open Bug Type: Output Control Operating System: Windows 2000 PHP Version: 4.3.0 New Comment: the cvs snapshot has the same behaviour. after a bit more poking, i've found that the "register_shutdown_function" does the same thing. my slightly expanded test script: <? chdir( "c:\\' ); function output_handler( $ob ) { $ob .= "2 - ".getcwd()."<br />\n"; return $ob; } function shutdown_function() { print "3 - ".getcwd()."<br />\n"; } ob_start( "output_handler" ); register_shutdown_function( "shutdown_function" ); print "1 - ".getcwd()."<br />\n"; ?> now outputs: 1 - c:\ 2 - d:\program files\apache 3 - d:\program files\apache the paths returned are different from my first example, because the script was tested straight after restarting apache. if i execute some other scripts that changed the chdir, then execute the test script, the results are the same as my first example.
