Как получить путь до program files?
Подскажите, возможно ли, получить путь до системной папки используя PHP?
Апач и ПХП стоит на этом же сервере под виндой. Нужно вывести пхп скриптом аудиофайлы с program files/mongo/audio, которые там хранятся.
Если никак, то может какими нибудь символьными ссылками добавить эту директорию или еще как то?

realpath
realpath() expands all symbolic links and resolves references to /./ , /../ and extra / characters in the input path and returns the canonicalized absolute pathname.
Parameters
Note:
Whilst a path must be supplied, the value can be an empty string. In this case, the value is interpreted as the current directory.
Return Values
Returns the canonicalized absolute pathname on success. The resulting path will have no symbolic link, /./ or /../ components. Trailing delimiters, such as \ and / , are also removed.
realpath() returns false on failure, e.g. if the file does not exist.
Note:
The running script must have executable permissions on all directories in the hierarchy, otherwise realpath() will return false .
Note:
For case-insensitive filesystems realpath() may or may not normalize the character case.
Note:
The function realpath() will not work for a file which is inside a Phar as such path would be a virtual path, not a real one.
Note:
On Windows, junctions and symbolic links to directories are only expanded by one level.
Note: Because PHP’s integer type is signed and many platforms use 32bit integers, some filesystem functions may return unexpected results for files which are larger than 2GB.
Examples
Example #1 realpath() example
chdir ( ‘/var/www/’ );
echo realpath ( ‘./../../etc/passwd’ ) . PHP_EOL ;
echo realpath ( ‘/tmp/’ ) . PHP_EOL ;
?>
The above example will output:
Example #2 realpath() on Windows
On windows realpath() will change unix style paths to windows style.
echo realpath ( ‘/windows/system32’ ), PHP_EOL ;
echo realpath ( ‘C:\Program Files\\’ ), PHP_EOL ;
?>
The above example will output:
C:\WINDOWS\System32 C:\Program Files

Because realpath() does not work on files that do not
exist, I wrote a function that does.
It replaces (consecutive) occurences of / and \\ with
whatever is in DIRECTORY_SEPARATOR, and processes /. and /.. fine.
Paths returned by get_absolute_path() contain no
(back)slash at position 0 (beginning of the string) or
position -1 (ending)
function get_absolute_path ( $path ) $path = str_replace (array( ‘/’ , ‘\\’ ), DIRECTORY_SEPARATOR , $path );
$parts = array_filter ( explode ( DIRECTORY_SEPARATOR , $path ), ‘strlen’ );
$absolutes = array();
foreach ( $parts as $part ) if ( ‘.’ == $part ) continue;
if ( ‘..’ == $part ) array_pop ( $absolutes );
> else $absolutes [] = $part ;
>
>
return implode ( DIRECTORY_SEPARATOR , $absolutes );
>
?>
A test:
var_dump ( get_absolute_path ( ‘this/is/../a/./test/.///is’ ));
?>
Returns: string(14) «this/a/test/is»
As you can so, it also produces Yoda-speak. 🙂

Needed a method to normalize a virtual path that could handle .. references that go beyond the initial folder reference. So I created the following.
function normalizePath ( $path )
$parts = array(); // Array to build a new path from the good parts
$path = str_replace ( ‘\\’ , ‘/’ , $path ); // Replace backslashes with forwardslashes
$path = preg_replace ( ‘/\/+/’ , ‘/’ , $path ); // Combine multiple slashes into a single slash
$segments = explode ( ‘/’ , $path ); // Collect path segments
$test = » ; // Initialize testing variable
foreach( $segments as $segment )
if( $segment != ‘.’ )
$test = array_pop ( $parts );
if( is_null ( $test ))
$parts [] = $segment ;
else if( $segment == ‘..’ )
if( $test == ‘..’ )
$parts [] = $test ;
if( $test == ‘..’ || $test == » )
$parts [] = $segment ;
>
else
$parts [] = $test ;
$parts [] = $segment ;
>
>
>
return implode ( ‘/’ , $parts );
>
?>
Will convert /path/to/test/.././..//..///..///../one/two/../three/filename
to ../../one/three/filename
realpath() is just a system/library call to actual realpath() function supported by OS. It does not work on a path as a string, but also resolves symlinks. The resulting path might significantly differs from the input even when absolute path is given. No function in this notes resolves that.
The suggestion on the realpath man page is to look for an existing parent directory. Here is an example:
function resolvePath ( $path ) if( DIRECTORY_SEPARATOR !== ‘/’ ) $path = str_replace ( DIRECTORY_SEPARATOR , ‘/’ , $path );
>
$search = explode ( ‘/’ , $path );
$search = array_filter ( $search , function( $part ) return $part !== ‘.’ ;
>);
$append = array();
$match = false ;
while( count ( $search ) > 0 ) $match = realpath ( implode ( ‘/’ , $search ));
if( $match !== false ) break;
>
array_unshift ( $append , array_pop ( $search ));
>;
if( $match === false ) $match = getcwd ();
>
if( count ( $append ) > 0 ) $match .= DIRECTORY_SEPARATOR . implode ( DIRECTORY_SEPARATOR , $append );
>
return $match ;
>
?>
The result will retrieve absolute path for non-existing relative path. Even if a path does not exists, there should be existing directory somewhere, for which the realpath could be obtained. If this is not within the relative path (i.e. even current working directory does not exists), getcwd() will retrieve absolute path, so some absolute path is returned (although in that case the PHP process could have huge problems).
Note: If you use this to check if a file exists, it’s path will be cached, and returns true even if the file is removed (use file_exists instead).
