dir -- Directory class

Description

class dir { dir ( string directory ) string path resource handle string read ( void ) void rewind ( void ) void close ( void ) }

A pseudo-object oriented mechanism for reading a directory. The given 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.

Examples

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.

<?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

cgi
