We can now replace the old fashioned way of listing the content from a directory!
the old way:
<?php
if ($handle = opendir('/home/fernando/temp')) {
while (false !== ($file = readdir($handle))) {
if ($file != "." && $file != "..") {
print "$file <br />";
}
}
closedir($handle);
}
?>
the new way:
<?php
$dir = new DirectoryIterator('/home/fernando/temp');
while($dir->valid()) {
if(!$dir->isDot()) {
print $dir->current()."<br />";
}
$dir->next();
}
?>
DirectoryIterator::__construct
(no version information, might be only in CVS)
DirectoryIterator::__construct -- Constructs a new dir iterator from a path

I wrote a function for finding all files in the current and in subdirectories.
The Code:
<?php
function getFiles(&$rdi,$depth=0) {
if (!is_object($rdi))
return;
for ($rdi->rewind();$rdi->valid();$rdi->next()) {
if ($rdi->isDot())
continue;
if ($rdi->isDir() || $rdi->isFile()) {
for ($i = 0; $i<=$depth;++$i)
echo ' ';
echo $rdi->current().'<br />';
if ($rdi->hasChildren())
getFiles($rdi->getChildren(),1+$depth);
}
}
}
getFiles(new RecursiveDirectoryIterator('.'));
?>
