(PHP 4, PHP 5)

getcwdПолучает имя текущего рабочего каталога


string getcwd ( void )

Возвращает имя текущего рабочего каталога.

Возвращаемые значения

Возвращает текущий рабочий каталог в случае успеха или FALSE в случае ошибки.

На некоторых вариантах Unix getcwd() вернет FALSE, если на каком-либо из родительских каталогов не установлен режим чтения или поиска, даже если он установлен на текущем каталоге. Больше информации о режимах доступа смотрите в документации функции chmod().


Пример #1 Пример использования getcwd()


// текущий каталог
echo getcwd() . "\n";


// текущий каталог
echo getcwd() . "\n";


Результатом выполнения данного примера будет что-то подобное:

getcwd() returns the path of the "main" script referenced in the URL.

dirname(__FILE__) will return the path of the script currently executing.

I had written a script that required several class definition scripts from the same directory. It retrieved them based on filename matches and used getcwd to figure out where they were.

Didn't work so well when I needed to call that first script from a new file in a different directory.

watch out:
working directory, and thus:
getcwd () 
is "/" while being into a register'ed shutdown function!!!

If your PHP cli binary is built as a cgi binary (check with php_sapi_name), the cwd functions differently than you might expect. 

say you have a script /usr/local/bin/purge
you are in /home/username 

php CLI: getcwd() gives you /home/username
php CGI: getcwd() gives you /usr/local/bin

This can trip you up if you're writing command line scripts with php. You can override the CGI behavior by adding -C to the php call: 

#!/usr/local/bin/php -Cq

and then getcwd() behaves as it does in the CLI-compiled version.

"On some Unix variants, getcwd() will return FALSE if any one of the parent directories does not have the readable or search mode set, even if the current directory does."

Just so you know, MacOS X is one of these variants (at least 10.4 is for me). You can make it work by applying 'chmod a+rx' to all folders from your site folder upwards.

Some server's has security options to block the getcwd()

Alternate option:

To get the username of the account:

$part explode('/'$dir);
$username $part[1];

If current directory is '/home/mike/public_html/' it would return mike.

I use this code to replicate the pushd and popd DOS commands in PHP:

= array();
pushd$dir )
array_push$g_DirStackgetcwd() );
chdir$dir );
popd( )
$dir array_pop$g_DirStack );
assert$dir !== null );
chdir$dir );

This allows you to change the current directory with pushd, then use popd to "undo" the directory change when you're done.

This function is often used in conjuction with basename(), i.e.

Take care if you use getcwd() in file that you'll need to include (using include, require, or *_once) in a script located outside of the same directory tree. 

//in /var/www/main_document_root/include/
if (strpos(getcwd(),'main_')>0) {
//code to set up main DB connection

//in home/cron_user/maintenance_scripts/some_maintenance_script.php
require_once ('/var/www/main_document_root/include/');

In the above example, the database connection will not be made because the call to getcwd() returns the path relative to the calling script ( /home/cron_user/maintenance_scripts ) NOT relative to the file where the getcwd() function is called.

If getcwd() returns nothing for you under Solaris with an NFS mounted subdirectory, you are running into an OS bug that is supposedly fixed in recent versions of Solaris 10.  This same OS bug effects the include() and require() functions as well.

This is a function to convert a path which looks something like this:


To a proper directory path:


function simplify_path($path) {

//saves our current working directory to a variable
$oldcwd getcwd();
//changes the directory to the one to convert
//$path is the directory to convert (clean up), handed over to the //function as a string


//change the cwd back to the old value to not interfere with the script


This function is really useful if you want to compare two filepaths which are not necesarily in a "cleaned up" stateIt works in *NIX and WINDOWS alike

When running PHP on the command line, if you want to include another file which is in the same directory as the main script, doing just
include './otherfile.php';
might not work, if you run your script like this:
/$ /path/to/script.php
because the current working dir will be set to '/', and the file '/otherfile.php' does not exist, because it is in '/path/to/otherfile.php'.
So, to get the directory in which the script resides, you can use this function:
function get_file_dir() {
$dir dirname(getcwd() . '/' $argv[0]);
$curDir getcwd();
$dir getcwd();
So you can use it like this:
include get_file_dir() . '/otherfile.php';
// or even..
Spent some time thinking this one out, maybe it helps someone :)

In response to myself: that function will not work for cases like:
/usr/bin$: /home/johndoe/Work/script.php
So here's a better and simpler way (I think this one works for all cases)
function get_file_dir() {
Knock yourself out :)

If you try to use getcwd() in a directory that is a symbolic link, getcwd() gives you the target of that link (similarly when parent etc. is symbolic link). There might be a better solution, but this worked for me (linux):

It appears there is a change in functionality in PHP5 from PHP4 when using the CLI tool.  Here is the example: -

cd /tmp

cat > foo.php << END
print getcwd() . "\n";

cd /

php -q /tmp/foo.php

PHP4 returns /tmp
PHP5 returns /

Something to be aware of.

if you link your php to /bin/linkedphp  and your php is at for ex /home/actual.php

when you run linkedphp in somewhere in your filesystem,
getcwd returns /bin instead of working dir,

solution: use dirname(__FILENAME__) instead

As you could read in
the CLI SAPI does - contrary to other SAPIs - NOT automatically change the current working directory to the one the started script resides in.

A very simple workaround to regain the behaviour you're used to from your "ordinary" webpage scripting is to include something like that at the beginning of your script:

dirname __FILE__ ) );

But because this is about reading or "finding" pathes, you might appreciate it if I share some more sophisticated tricks I frequently use in CLI scripts ...

// Note: all pathes stored in subsequent Variables end up with a DIRECTORY_SEPARATOR

// how to store the working directory "from where" the script was called:
$initial_cwd preg_replace'~(\w)$~' '$1' DIRECTORY_SEPARATOR realpathgetcwd() ) );

// how to switch symlink-free to the folder the current file resides in:
chdirdirname realpath __FILE__ ) ) );

// how to store the former folder in a variable:
$my_folder dirnamerealpath__FILE__ ) ) . DIRECTORY_SEPARATOR;

// how to get a path one folder up if $my_folder ends with \class\ or /class/ :
$my_parent_folder preg_replace'~[/\\\\]class[/\\\\]$~' DIRECTORY_SEPARATOR $my_folder );

// how to get a path one folder up in any case :
$my_parent_folder preg_replace'~[/\\\\][^/\\\\]*[/\\\\]$~' DIRECTORY_SEPARATOR $my_folder );

// how to make an array of OS-style-pathes from an array of unix-style-pathes
// (handy if you use config-files or so):
foreach( $unix_style_pathes as $unix_style_path )
$os_independent_path[] = str_replace'/' DIRECTORY_SEPARATOR $unix_style_path );

Be aware when calling getcwd() in directories consisting of symlinks.

getcwd()  is the equivalent of shell command "pwd -P" which resolves symlinks.

The shell command "pwd" is the equivalent of "pwd -L" which uses PWD from the environment without resolving symlinks. This is also the equivalent of calling getenv('PWD').
2016-03-06 01:44:41
getcwd() appears to call the equivalent of PHP's realpath() on the path.  It never returns symlinks, but always the actual directory names in the path to the current working directory.
