Bug #14839 Updated: getcwd() and `pwd` report incorrect directory

ID: 14839 Updated by: edink Reported By: php@chaska.com Old Status: Open Status: Closed Bug Type: *Directory/Filesystem functions Operating System: Linux, FreeBSD, Solaris PHP Version: 4.0.5 New Comment: Closing the report. Previous Comments: ------------------------------------------------------------------------ [2002-01-04 05:01:54] edink@php.net There is nothing wrong with getcwd(). The problem is that php changes current working directory to the script's. This makes sense if you think of CGI scripts, but makes no sense if you write command line programs. That's way a new command line switch (-C) was introduced in PHP 4.1.0 which prevents PHP from chdir'ing into script's directory. So changing the first line of your script to #!/usr/local/bin/php -qC (and upgrading to 4.1) should fix the problem. ------------------------------------------------------------------------ [2002-01-04 00:47:58] imajes@php.net Ok, some comments, if i may. Firstly, I have verified this behaviour, however (and I could be wrong), this is not unexpected. The script executes relavtive to the directory it exists within, not the directory you are currently in. I can't particularly explain why, but this kind of makes sense. If you had a script in some unsafe directory, allowing the moving and deleting of files, and you could run it in a secured directory, in which the php process had sufficient access, and affect the files there, would that not present potential security risks? Anyhow, i could be wrong, so don't take what i said as corret. ------------------------------------------------------------------------ [2002-01-04 00:22:32] php@chaska.com Oh, I suppose you want my configure line, even though it really doesn't make a difference. Here it is: CONFIGURE_COMMAND = './configure' '--with-gd=/usr/local' '--with-mysql' '--with-openssl' '--with-apxs=/usr/local/sbin/apxs' '--prefix=/usr/local' ------------------------------------------------------------------------ [2002-01-04 00:16:48] php@chaska.com This problem was previously reported by someone against PHP 4.0.6 in Bug ID # 14214. Latest comment on the that reports says they are going to close it for lack of information. This bug has existed in every version of PHP I've used since 1999. It fails on Linux, FreeBSD and Solaris. Both mistaken report the directory which contains the script being run, NOT the current working directory. This fails when run from a directory other than where the script is saved: #! /usr/local/bin/php -q <?php system("pwd"); echo pwd; echo getcwd(); echo "\n"; ?> Under any POSIX-compliant OS, or just about any version of Unix, calling the getcwd(3) library routine should get the correct result. It appears the PHP interpreter startup is changing directories without saving this value first, since even calling the OS gives incorrect values. ------------------------------------------------------------------------ Edit this bug report at http://bugs.php.net/?id=14839&edit=1
