(PHP 4, PHP 5, PHP 7)
dir — Return an instance of the Directory class
dir ( string $directory [, resource $context ] ) : Directory
A pseudo-object oriented mechanism for reading a directory. The given directory is opened.
directory
Directory to open
context
Note: Context support was added with PHP 5.0.0. For a description of
contexts, refer to Streams.
Returns an instance of Directory, or null with wrong parameters, or false in case of another error.
Example #1 dir() example
Please note the fashion in which Directory::read()'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.
<?php
$d = dir("/etc/php5");
echo "Handle: " . $d->handle . "\n";
echo "Path: " . $d->path . "\n";
while (false !== ($entry = $d->read())) {
echo $entry."\n";
}
$d->close();
?> The above example will output something similar to:
Handle: Resource id #2 Path: /etc/php5 . .. apache cgi cli
Note:
The order in which directory entries are returned by the read method is system-dependent.
