Example #1 DirectoryIterator::isWritable() example
This example lists the files and directories which can be opened for writing in the directory containing the script.
<?php
$iterator = new DirectoryIterator ( dirname ( __FILE__ ));
foreach ( $iterator as $fileinfo ) {
if ( $fileinfo -> isWritable ()) {
echo $fileinfo -> getFilename () . "\n" ;
