A pseudo-object oriented mechanism for reading a directory. The given directory is opened.
Directory to open
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.
The order in which directory entries are returned by the read method is system-dependent.
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
