Method Details

canonicalize() public static method

During normalization, all slashes are replaced by forward slashes ("/"). Furthermore, all "." and ".." segments are removed as far as possible. ".." segments at the beginning of relative paths are not removed. php echo Path::canonicalize("\webmozart\puli\..\css\style.css"); => /webmozart/css/style.css echo Path::canonicalize("../css/./style.css"); => ../css/style.css This method is able to deal with both UNIX and Windows paths.
Since: 1.0 Added method.
Since: 2.0 Method now fails if $path is not a string.
Since: 2.1 Added support for `~`.
public static canonicalize ( string $path ) : string
$path string A path string.
return string The canonical path.

changeExtension() public static method

Changes the extension of a path string.
Since: 1.1 Added method.
Since: 2.0 Method now fails if $path or $extension is not a string.
public static changeExtension ( string $path, string $extension ) : string
$path string The path string with filename.ext to change.
$extension string New extension (with or without leading dot).
return string The path string with new file extension.

getDirectory() public static method

This method is similar to PHP's dirname(), but handles various cases where dirname() returns a weird result: - dirname() does not accept backslashes on UNIX - dirname("C:/webmozart") returns "C:", not "C:/" - dirname("C:/") returns ".", not "C:/" - dirname("C:") returns ".", not "C:/" - dirname("webmozart") returns ".", not "" - dirname() does not canonicalize the result This method fixes these shortcomings and behaves like dirname() otherwise. The result is a canonical path.
Since: 1.0 Added method.
Since: 2.0 Method now fails if $path is not a string.
public static getDirectory ( string $path ) : string
$path string A path string.
return string The canonical directory part. Returns the root directory if the root directory is passed. Returns an empty string if a relative path is passed that contains no slashes. Returns an empty string if an empty string is passed.

return string The extension of the file path (without leading dot).

getFilename() public static method

return string The file name without extension.

getHomeDirectory() public static method

getLongestCommonBasePath() public static method

Dot segments ("." and "..") are removed/collapsed and all slashes turned into forward slashes. php $basePath = Path::getLongestCommonBasePath(array( '/webmozart/css/style.css', '/webmozart/css/..' )); => /webmozart The root is returned if no common base path can be found: php $basePath = Path::getLongestCommonBasePath(array( '/webmozart/css/style.css', '/puli/css/..' )); => / If the paths are located on different Windows partitions, null is returned. php $basePath = Path::getLongestCommonBasePath(array( 'C:/webmozart/css/style.css', 'D:/webmozart/css/..' )); => null

public static join ( string[] | string $paths ) : string
$paths string[] | string Path parts as parameters or array.
return string The joint path.

makeAbsolute() public static method

Usually, the relative path is appended to the given base path. Dot segments ("." and "..") are removed/collapsed and all slashes turned into forward slashes. php echo Path::makeAbsolute("../style.css", "/webmozart/puli/css"); => /webmozart/puli/style.css If an absolute path is passed, that path is returned unless its root directory is different than the one of the base path. In that case, an exception is thrown. php Path::makeAbsolute("/style.css", "/webmozart/puli/css"); => /style.css Path::makeAbsolute("C:/style.css", "C:/webmozart/puli/css"); => C:/style.css Path::makeAbsolute("C:/style.css", "/webmozart/puli/css"); InvalidArgumentException If the base path is not an absolute path, an exception is thrown. The result is a canonical path.
Since: 1.0 Added method.
Since: 2.0 Method now fails if $path or $basePath is not a string.
Since: 2.2.2 Method does not fail anymore of $path and $basePath are absolute, but on different partitions.

$path string A path to make absolute.
$basePath string An absolute base path.
return string An absolute path in canonical form.

makeRelative() public static method

The relative path is created relative to the given base path: php echo Path::makeRelative("/webmozart/style.css", "/webmozart/puli"); => ../style.css If a relative path is passed and the base path is absolute, the relative path is returned unchanged: php Path::makeRelative("style.css", "/webmozart/puli/css"); => style.css If both paths are relative, the relative path is created with the assumption that both paths are relative to the same directory: php Path::makeRelative("style.css", "webmozart/puli/css"); => ../../../style.css If both paths are absolute, their root directory must be the same, otherwise an exception is thrown: php Path::makeRelative("C:/webmozart/style.css", "/webmozart/puli"); InvalidArgumentException If the passed path is absolute, but the base path is not, an exception is thrown as well: php Path::makeRelative("/webmozart/style.css", "webmozart/puli"); InvalidArgumentException If the base path is not an absolute path, an exception is thrown. The result is a canonical path.
Since: 1.0 Added method.
Since: 2.0 Method now fails if $path or $basePath is not a string.
public static makeRelative ( string $path, string $basePath ) : string
$path string A path to make relative.
$basePath string A base path.
return string A relative path in canonical form.

normalize() public static method

During normalization, all slashes are replaced by forward slashes ("/"). Contrary to {@link canonicalize()}, this method does not remove invalid or dot path segments. Consequently, it is much more efficient and should be used whenever the given path is known to be a valid, absolute system path. This method is able to deal with both UNIX and Windows paths.
Since: 2.2 Added method.
public static normalize ( string $path ) : string
$path string A path string.
return string The normalized path.
