chdir - Change directory

SYNOPSIS

       bool chdir (string  $directory)

		- The new current directory

RETURN VALUES

	Returns TRUE on success or FALSE on failure.

ERRORS
/EXCEPTIONS
	Throws an error of level E_WARNING on failure.

EXAMPLES

       Example #1

	      chdir(3) example

	      <?php

	      // current directory
	      echo getcwd() . "
";

	      chdir('public_html');

	      // current directory
	      echo getcwd() . "
";

	      ?>

	      The above example will output something similar to:

	      /home/vincent
	      /home/vincent/public_html

NOTES

       Note

	      When  safe mode is enabled, PHP checks whether the directory in which the script is operating has the same UID (owner) as the script
	      that is being executed.

NAME

       chdir, fchdir - change working directory

SYNOPSIS

       #include <unistd.h>

       int chdir(const char *path);
       int fchdir(int fd);

   Feature Test Macro Requirements for glibc (see feature_test_macros(7)):

       fchdir():
	   _BSD_SOURCE || _XOPEN_SOURCE >= 500 || _XOPEN_SOURCE && _XOPEN_SOURCE_EXTENDED
	   || /* Since glibc 2.12: */ _POSIX_C_SOURCE >= 200809L

DESCRIPTION

       chdir() changes the current working directory of the calling process to the directory specified in path.

       fchdir() is identical to chdir(); the only difference is that the directory is given as an open file descriptor.

RETURN VALUE

       On success, zero is returned.  On error, -1 is returned, and errno is set appropriately.

ERRORS

       Depending on the file system, other errors can be returned.  The more general errors for chdir() are listed below:

       EACCES Search permission is denied for one of the components of path.  (See also path_resolution(7).)

       EFAULT path points outside your accessible address space.

       EIO    An I/O error occurred.

       ELOOP  Too many symbolic links were encountered in resolving path.

       ENAMETOOLONG
	      path is too long.

       ENOENT The file does not exist.

       ENOMEM Insufficient kernel memory was available.

       ENOTDIR
	      A component of path is not a directory.

       The general errors for fchdir() are listed below:

       EACCES Search permission was denied on the directory open on fd.

       EBADF  fd is not a valid file descriptor.

CONFORMING TO

       SVr4, 4.4BSD, POSIX.1-2001.

NOTES

       The current working directory is the starting point for interpreting relative pathnames (those not starting with '/').

       A  child  process  created via fork(2) inherits its parent's current working directory.	The current working directory is left unchanged by
       execve(2).
