listing all jpg files in dir and subdirs - php

Question

How can I list all jpg files in a given directory and its subdirectories in PHP5 ?
I thought I could write a glob pattern for that but I can't figure it out.
thanx, b.

Answer 1

You can use a RecursiveDirectoryIterator with a filter:
class ImagesFilter extends FilterIterator
{
public function accept()
{
$file = $this->getInnerIterator()->current();
return preg_match('/\.jpe?g$/i', $file->getFilename());
}
}
$it = new RecursiveDirectoryIterator('/var/images');
$it = new ImagesFilter($it);
foreach ($it as $file)
{
// Use $file here...
}
$file is an SplFileInfo object.

Answer 2

without doing it for you. recursion is the answer here. a function that looks in a dir and gets a list of all files. filters out only th jpg's then calls its self if i finds any sub dirs

Answer 3

Wish I had time to do more & test, but this could be used as a starting point: it should (untested) return an array containing all the jpg/jpeg files in the specified directory.
function load_jpgs($dir){
$return = array();
if(is_dir($dir)){
if($handle = opendir($dir)){
while(readdir($handle)){
echo $file.'<hr>';
if(preg_match('/\.jpg$/',$file) || preg_match('/\.jpeg$/',$file)){
$return[] = $file;
}
}
closedir($handle);
return $return;
}
}
return false;
}
