I have a script that grabs images from a folder called “images” and displays them. I would like to modify it to also display the images in all of the subfolders. Can someone help me?
[php]<?php
ini_set( “display_errors”, 0);
//Your folder
$files = glob(“images/.”);
function sortnewestfilesfirst($a, $b) {
return filemtime($b) - filemtime($a);
}
usort($files, “sortnewestfilesfirst”);
$colCnt=0;
echo ‘
| ’;
$num = $files[$i]; echo ’ echo ‘ | ’;
I personally never had a use for this type of coding myself yet… but from what i can gather from a online tutorial on Google… credit: http://www.linuxweblog.com/node/327
File Name: list_pics.php
[php]<?php
// file name: list_pics.php
global $startDir;
/**
List Directories function, which transverses sub-folders
listing out the image files that exists within it.
*/
function listDir( $path ) {
global $startDir;
$handle = opendir( $path );
while (false !== ($file = readdir($handle))) {
if( substr( $file, 0, 1 ) != ‘.’ ) {
if( is_dir( $path.’/’.$file ) ) {
listDir( $path.’/’.$file );
}
else {
if( @getimagesize( $path.’/’.$file ) ) {
/*
// Uncomment if using with the below "pic.php" script to
// encode the filename and protect from direct linking.
$url = 'http://domain.tld/images/pic.php?pic='
.urlencode( str_rot13( substr( $path, strlen( $startDir )+1 ).'/'.$file ) );
*/
$url='http://domain.tld/images/'.
substr( $path, strlen( $startDir )+1 ).'/'.$file;
// You can customize the output to use img tag instead.
echo "<a href='".$url."'>".$url."</a><br>";
}
}
}
}
closedir( $handle );
} // End listDir function
$startDir = ‘.’;
listDir( $startDir );
?>

File Name: pic.php
[php]<?php

$f = trim( $_GET[‘pic’] );
if( ( substr( $f, 0, 1 ) == ‘.’ ) || ( substr( $f, 0, 1 ) == ‘/’ ) ) {
return false;

return false;
} else {
switch( $imgType ) {
case 1:

Here is an example of how to scan all sub-directories using PHP’s RecursiveDirectoryIterator class
[php]
$path = ‘images/’; // define the path to your images folder
$objs = new RecursiveIteratorIterator(new RecursiveDirectoryIterator($path), RecursiveIteratorIterator::SELF_FIRST);
foreach($objs as $obj) {
if (!$obj->isFile()) {
continue; // skip all directories
}
// check if file is an image type
$extension = pathinfo($obj->getPathname(), PATHINFO_EXTENSION); // get extension
if (in_array($extension, array(‘jpg’, ‘gif’, ‘png’))) {
// this is where you would output your IMG code
echo $obj->getPathname() . “\n”;
}
}
[/php]
