We can find absolute path in different ways on a web server using PHP, I am showing some of that practices here
echo realpath(dirname(__FILE__)); // realpath() , This function removes all symbolic path and returns the absolute path name , this function return false an failure //dirname() , Returns the parent directory path // __FILE__ ,The full path and file name of the file
echo getcwd(); //getcwd(), function get the current working directory , returns true on success return false on failure
print_r($_SERVER['DOCUMENT_ROOT']); //$_SERVER is an array with headers,path,script location information. //$_SERVER['DOCUMENT_ROOT'] , returns the current executing script directory
// absolute path with file name echo $_SERVER['SCRIPT_FILENAME'];
The description of the functions used in this tutorial are as follows
realpath() , This function removes all symbolic path and returns the absolute path name , this function return false an failure
dirname() , Returns the parent directory path
getcwd(), function get the current working directory , returns true on success return flase on failure
$_SERVER is an array with headers,path,script location information.
