A pseudo-object oriented mechanism for reading a directory. The
directory is opened. Two properties
are available once the directory has been opened. The handle
property can be used with other directory functions such as
readdir(), rewinddir() and
closedir(). The path property is set to path
the directory that was opened. Three methods are available:
read, rewind and close.
Example 1. dir() example
Please note the fashion in which dir()'s return value is checked in the example below. We are explicitly testing whether the return value is identical to (equal to and of the same type as--see Comparison Operators for more information) FALSE since otherwise, any directory entry whose name evaluates to FALSE will stop the loop.
The above example will output something similar to:
Note: The order in which directory entries are returned by the read method is system-dependent.
Note: This defines the internal class Directory, meaning that you will not be able to define your own classes with that name. For a full list of predefined classes in PHP, please see Predefined Classes.
