getcwd - Gets the current working directory
Manual
getcwd(
Gets the current working directory.
Parameters
This function has no parameters.
Return Values
Returns the current working directory on success, or false on failure.
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. See chmod for more information on modes and permissions.
Notes
Caution:
If the PHP interpreter has been built with ZTS (Zend Thread Safety) enabled, the current working directory returned by getcwd may be different from that returned by operating system interfaces. External libraries (invoked through FFI) which depend on the current working directory will be affected.
