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.
