Méthodes publiques

Méthode	Description
CanReadWithoutLock ( ) : bool
CanWriteWithoutLock ( ) : bool
CheckAccess ( string filename, CheckAccessMode mode, CheckAccessOptions options ) : bool	Performs all checks on a path passed to a PHP function. This method performs a check similar to `safe_mode.c: php_checkuid_ex()` together with `open_basedir` check. The filename may be one of the following: A relative path. The path is resolved regarding the `include_path` too if required and checking continues as in the next case. An absolute path. The file or directory is checked for existence and for access permissions¹ according to the given mode. ¹ Regarding the `open_basedir` configuration option. File access permissions are checked at the time of file manipulation (opening, copying etc.).
ResolvePath ( string &path, StreamWrapper &wrapper, CheckAccessMode mode, CheckAccessOptions options ) : bool	Merges the path with the current working directory to get a canonicalized absolute pathname representing the same file. This method is an analogy of `main/safe_mode.c: php_checkuid`. Looks for the file in the `include_path` and checks for `open_basedir` restrictions.

CheckAccess() public static méthode

Performs all checks on a path passed to a PHP function.

This method performs a check similar to safe_mode.c: php_checkuid_ex() together with open_basedir check.

The filename may be one of the following: A relative path. The path is resolved regarding the include_path too if required and checking continues as in the next case. An absolute path. The file or directory is checked for existence and for access permissions¹ according to the given mode. ¹ Regarding the open_basedir configuration option. File access permissions are checked at the time of file manipulation (opening, copying etc.).

If the file can not be accessed /// and the is not set.

public static CheckAccess ( string filename, CheckAccessMode mode, CheckAccessOptions options ) : bool
filename	string	A resolved path. Must be an absolute path to a local file.
mode	CheckAccessMode	One of the .
options	CheckAccessOptions	true to suppress error messages.
Résultat	bool

ResolvePath() public static méthode

Merges the path with the current working directory to get a canonicalized absolute pathname representing the same file.

This method is an analogy of main/safe_mode.c: php_checkuid. Looks for the file in the include_path and checks for open_basedir restrictions.

Security violation - when the target file /// lays outside the tree defined by open_basedir configuration option.

public static ResolvePath ( string &path, StreamWrapper &wrapper, CheckAccessMode mode, CheckAccessOptions options ) : bool
path	string	An absolute or relative path to a file.
wrapper	StreamWrapper	The wrapper found for the specified file or null if the path resolution fails.
mode	CheckAccessMode	The checking mode of the method (file, directory etc.).
options	CheckAccessOptions	Additional options for the method.
Résultat	bool
