I have this function that creates an array of a directories output.
public function getDirContents( $path )
{
$dir = new RecursiveDirectoryIterator( $path, FilesystemIterator::SKIP_DOTS );
// Flatten the recursive iterator, folders come before their files
$it = new RecursiveIteratorIterator( $dir, RecursiveIteratorIterator::SELF_FIRST );
// Maximum depth is 1 level deeper than the base folder
$it->setMaxDepth(1);
$results = array();
// Basic loop displaying different messages based on file or folder
foreach ($it as $contents)
{
$fileInfo = array();
if ( $contents->isFile() )
{
$fileInfo['dir'] = $it->getSubPath();
$fileInfo['file'] = $contents->getFilename();
$results[] = $fileInfo;
}
}
return $results;
}
I have this in a class that I created and it works as expected. I have an older script that I haven't rewritten to use this class. so I placed this function (minus the public) in another file that contains random common functions and include the file into my old script. However, when I call it I get the error
PHP Fatal error: Class 'FilesystemIterator' not found in /aaa/bbb/ccc/ddd/common.php on line 745
If I remove the FilesystemIterator::SKIP_DOTS it works fine except I guess it loses that functionality. I'm curious why this is happening.
Other things that may or may not explain what could be occuring.
The class that I use it in successfully is part of the main site.
The script where it errs is actually a subdomain.
I'm using php 5.3 (single file)
-- This is bluehost's config for picking a version of php and this is how mine is set up.
PHP 5.3 (Single php.ini) Same as PHP 5.3, but all subdirectories will use ~/public_html/php.ini
This is why I was under the impression that my subdirectory (subdomain) would use that file.
The httaccess in the subdomain vs the main are not the same.
I'm not sure if those tidbits help but I'm at lose and I'm fairly new at this.
Any help would be appreciated.

I am trying to create a .phar file from my web application. Following the php documentation's example I tried the following for this purpose.
<?php
$srcRoot = __DIR__ . "/../app";
$buildRoot = __DIR__ . "/../build";
$p = new Phar("$buildRoot/build.phar", 0, 'build.phar');
$p->buildFromIterator(
new RecursiveIteratorIterator(
new RecursiveDirectoryIterator($srcRoot)
),
$srcRoot
);
However I got the following error. I dont have any idea about the error. What is wrong with the code?
PHP Fatal error: Uncaught exception 'UnexpectedValueException' with message
'Iterator RecursiveIteratorIterator returned a path "D:\site\app" that is
not in the base directory "D:\site\app"'
in D:\site\tools\create-phar.php:7
The source of the problem is that RecursiveDirectoryIterator also lists the dot files - . and ...
When iterating over /path/to/foo it also lists /path/to/foo/. and /path/to/foo/.. which goes to the parent directory - outside the base directory.
Thus you have to prevent the inclusion of the ".." files, which is most easily achieved with FilesystemIterator::SKIP_DOTS as second parameter to DirectoryIterator:
new RecursiveDirectoryIterator($srcRoot, FilesystemIterator::SKIP_DOTS)
(#cweiske -- I just realized you beat me to it, I'll make sure to refresh the page next time, my sincerest apologies!)
You need just a slight edit to skip over the unix paths /. and /..:
<?php
$srcRoot = __DIR__ . "/../app";
$buildRoot = __DIR__ . "/../build";
$p = new Phar("$buildRoot/build.phar", 0, 'build.phar');
$p->buildFromIterator(
new RecursiveIteratorIterator(
new RecursiveDirectoryIterator($srcRoot, FilesystemIterator::SKIP_DOTS)
),
$srcRoot
);
Box makes it very easy to create PHAR archives from your source files. Basically you first add a configuration file and then you can create your PHAR file by simply invoking box build on the command line.
There is a great blog post by Matthieu Moquet describing how he used Box to simplify the distribution of a PHP Cli application. Personally, I've also been using Box for a CLI application, however the official project description is not limited to CLI applications, but rather summarizes the Box project as:
An application for building and managing Phars.
The Box project provides the PHAR build script and takes care of setting all paths correctly, so this might solve your problem.
The solution proposed by #cweiske is brilliant. In some situations, however, you may need the ability to add more directory path exclusions. Have a look at this example that excludes any references to the .git directory, using FilterIterator:
// create phar
$p = new Phar($pharFile, 0, $pharFile);
// produce iteration which excludes any references to values assigned to $excludes
$iterator = new RecursiveIteratorIterator(
new RecursiveDirectoryIterator($path, FilesystemIterator::SKIP_DOTS)
);
$filter = new class($iterator) extends FilterIterator {
public static $excludes = [];
public function accept()
{
$item = $this->current();
$actual = 0;
foreach (self::$excludes as $exclude) {
$actual += (int) boolval(strpos($item->getPath(), $exclude));
}
return ($actual === 0);
}
};
$filter::$excludes = ['.git'];
$p->buildFromIterator($filter, $path);
Have a look at php.ini file to check the value of phar.readonly field.
It must be 0 to create phar archive.
Ref: http://php.net/manual/en/phar.configuration.php#ini.phar.readonly
I want to loop all the sub dirs in the main dirs, where I keeps all my classes, for instance,
core/
model/
page/
class_1.php
class_2.php
menu/
class_3.php
and so on...
So this is my autoload function that I place it in the init.php,
function autoload_multiple_directory($class_name){
// List all the class directories in the array.
$array_directories = array(
'core/controller/',
'core/model/',
'core/helper/'
);
// When you use namespace in a class, you get something like this when you auto load that class \foo\tidy.
// So use explode to split the string and then get the last item in the exloded array.
$parts = explode('\\', $class_name);
//print_r($parts);
// Set the class file name.
$file_name = strtolower(end($parts)).'.php';
// $file_name = 'class_'.strtolower($class_name).'.php';
// Loop the array.
foreach($array_directories as $path_directory){
$recursive_directory = new RecursiveDirectoryIterator($path_directory);
foreach (new RecursiveIteratorIterator($recursive_directory) as $filename => $file) {
if(file_exists(WEBSITE_DOCROOT.$file->getPath().'/'.$file_name)){
include WEBSITE_DOCROOT.$file->getPath().'/'.$file_name;
}
}
/* no problem with this, but I cannot loop the sub dirs...
if(file_exists(WEBSITE_DOCROOT.$path_directory.$file_name)){
include WEBSITE_DOCROOT.$path_directory.$file_name;
}
*
*/
}
}
spl_autoload_register('autoload_multiple_directory');
But then I get this error message,
Fatal error: Cannot redeclare class Common in C:\wamp\www\xxx\core\helper\Common.php on line 6
There is only one Common class in my project. Why does it say more than once or redeclare?
But if you look at the if(file_exists(WEBSITE_DOCROOT.$path_directory.$file_name)) that I comment out - it has no problem to load the classes. The problem of this initial loop is that it does not loop the sub dirs in a main dir, for instance, core/model/
Any ideas why and what should I do to loop the sub dirs of a main dir?
EDIT:
The problem comes from RecursiveDirectoryIterator - it loops the directories and lists all files. But what I want is only the sub directories.
Is there any chance that there are more than one copy of Common.php file exists in those folders?
Because your code does not break after including a class file the autoloader will continue seeking other files with the same name in the folder tree, and would lead to Fatal error: Cannot redeclare class XXX error. Adding break could fix the problem.
// Loop the array.
$isClassFound = false;
foreach($array_directories as $path_directory){
$recursive_directory = new RecursiveDirectoryIterator($path_directory);
foreach (new RecursiveIteratorIterator($recursive_directory) as $filename => $file) {
if(file_exists(WEBSITE_DOCROOT.$file->getPath().'/'.$file_name)){
include WEBSITE_DOCROOT.$file->getPath().'/'.$file_name;
$isClassFound = true;
}
if ($isClassFound) break;
}
if ($isClassFound) break;
}
However, the nature of your autoloader seems like it should not allow any duplicated class file names. Maybe you can write a name duplication checker to guarantee uniqueness.
EDIT:
I removed the class_exists() part from my answer because using it doesn't make much sense. Anyway, since you saw that version of my answer, and you asked me where to put class_exists() via the comment, I'll revive the code sample. you can add the following code at the beginning of the autoloader.
if (class_exists($class_name,false)) // give false to avoid automatic loading
return;
Open the start menu. In the text box write cmd, wait for the cmd program to pop up and then hit Enter.
Once the terminal window opens navigate to your root folder and then do a recursive search (through all files and folders) for the class' name:
cd C:\wamp\www\xxx
findstr /SNIP /C:"class common" *.php
There should be more than one declaration of the class.
im currently working on some sort of upload with automatic video conversion. At the moment i am executing a php script via php shell command after the upload is finished so the user doesn't have to wait until the conversion is completed. Like so:
protected function _runConversionScript() {
if (!exec("php -f '" . $this->_conversionScript . "' > /dev/null &"))
return true;
return false;
}
Now in my conversion script file i am using functions from another class "UploadFunctions" to update the status in the database (like started, converted, finished...). The problem there is though that this UploadFunctions class inherits from another class "Controller" where for example the database connection gets established. Currently i am using spl_autoloader to search specific directories for the files needed (for example controller.php), but because the conversion script is out of context with the whole autoloader stuff it doesn't recognize the Controller class and throws an fatal php error.
Here is some code from the conversion script:
require_once('uploadfunctions.php');
$upload_func = new UploadFunctions();
// we want to make sure we only process videos that haven't already
// been or are being processed
$where = array(
'status' => 'queued'
);
$videos = $upload_func->getVideos($where);
foreach ($videos as $video) {
// update database to show that these videos are being processed
$update = array(
'id' => $video['id'],
'status' => 'started'
);
// execute update
$upload_func->updateVideo($update);
.........
Am i doing this completly wrong or is there a better way to accomplish this? If you need more code or information please let me know!
Thanks a lot
Here is my spl_autoload code:
<?php
spl_autoload_register('autoloader');
function autoloader($class_name) {
$class_name = strtolower($class_name);
$pos = strpos($class_name ,'twig');
if($pos !== false){
return false;
}
$possibilities = array(
'..'.DIRECTORY_SEPARATOR.'globals'.DIRECTORY_SEPARATOR.$class_name.'.php',
'controller'.DIRECTORY_SEPARATOR.$class_name.'.php',
'..'.DIRECTORY_SEPARATOR.'libs'.DIRECTORY_SEPARATOR.$class_name.'.php',
'local'.DIRECTORY_SEPARATOR.$class_name.'.php'
);
foreach ($possibilities as $file) {
if(class_exists($class_name) != true) {
if (file_exists($file)) {
include_once($file);
}
}
}
}
?>
I have my project divided into subfolders wich represent the functionality, for example upload, myaccount and gallery.. in every subfolder there are also 2 other folders: controller and local. Controller is the class controlling this part (upload for example) and local is the folder where i am putting the local classes wich are needed. The controller class gets called from the index.php wich is located in the sub-project folder. "libs" and "global" are just projectwide classes, like database, user and so on.
This is an example of my folder structure:
www/index.php // main site
www/upload/index.php // calls the controller for upload and initializes the spl_autoload
www/upload/controller/indexcontroller.php // functionality for the upload
www/upload/local/processVideo.php // this is the conversion script.
I am fairly new to spl_autoload function. In my opinion the spl_autoload is not getting called if my script is calling: "php -f processVideo.php", isn't it?
PHP relative paths are calculated from the path where PHP binary is called.
I suggest you to use __DIR__ constant to avoid that behavior
http://php.net/manual/en/language.constants.predefined.php
I was actually able to resolve the issue. I had to include the spl_autoload_register function inside the conversion script so that it was able to locate the files. This was an issue because the conversion script is not build into my framework an so it isn't able to load the classes from the framework autoloader.
I am trying to use elliothaughins Socialize system for code igniter,
However I keep getting
Message: include(application/third_party/config/socializenetworks.php): failed to open stream: No such file or directory
I have traced this issue and when I call
$this->load->add_package_path(APPPATH.'third_party/socialize/');
In the loader class if I do die($path) I only get application/third_party.
It seems strange though as the code for the controller is
class SocializeController extends CI_Controller {
function __construct(){
parent::__construct();
parse_str($_SERVER['QUERY_STRING'], $_GET);
$this->load->add_package_path(APPPATH.'third_party/socialize/');
$this->_autoload();
}
private function _autoload(){
$this->load->model('socialize_migration_model');
$autoload = array();
include(APPPATH.'third_party/socialize/config/autoload'.EXT);
foreach ( $autoload as $type => $files ) {
$type = ($type == 'libraries') ? 'library' : $type;
foreach ( $files as $file ){
$this->load->$type($file);
}
}
}
public function data($key, $value)
{
$this->load->vars(array($key => $value));
}
}
Which as you can see it is calling a model, which it successfully loads,
It is when It gets to the autoloader where it loads the libraries where it breaks,
The particular library that is giving issue starts like
class SocializeNetworks {
private $_obj;
private $_networks = array();
function __construct(){
$this->_obj =& get_instance();
$this->_obj->load->config('socializenetworks'); // this is the line we die on :(
So,
Whats going on here and how can I fix it?
I traced this down to a bug just yesterday in the CI v2.0.2 code base. Essentially what is happening is you are adding an additional path to check for files in (which is correct) and the load method loops through each of the paths until it finds the file you are looking for.
If you output your CI object, you'll probably see that what you are looking for is there, but it's still failing.
In the file /codeigniter/core/Config.php where the load method is, for some reason, the $found=false; isn't reset on each iteration through the path loop, so if the path is found on the first run (as it was in my case) then $found is set to true, but then on subsequent runs, $found is still true, so it tries to include a non-existent file.
I solved this by moving the declaration for the $found variable to just below the start of the first foreach loop. This way it resets it each time. I reported the bug, so hopefully it will be addressed in subsequent versions.
this is my third question so far on stackoverflow :D
i am defining files and their location on my first_run.php files,
the files that i define here is those files containing classes, helper functions
and any other files required
at early development, this first_run.php contains only a few lines of codes
but the line is increasing gradually as i add some new classes or new files to be included
and since i group the file's location inside a particular folder, i figure that maybe i can scan the folder, put the name of the files retrieved into an array and then loop the require_once, so that i dont have to edit first_run.php every time i add a new file inside the folder.
my fisrt approach is using scandir()
before:
defined('INC_PATH') ? null : define('INC_PATH', SITE_ROOT.DS.'includes');
defined('MEMBERS') ? null : define('MEMBERS', INC_PATH.DS.'models'.DS.'members');
require_once(MEMBERS.DS.'member.php');
require_once(MEMBERS.DS.'phone.php');
require_once(MEMBERS.DS.'profile.php');
require_once(MEMBERS.DS.'talent.php');
require_once(MEMBERS.DS.'profile_picture.php');
require_once(MEMBERS.DS.'audio.php');
require_once(MEMBERS.DS.'video.php');
require_once(MEMBERS.DS.'gallery.php');
require_once(MEMBERS.DS.'statistik.php');
require_once(MEMBERS.DS.'inbox.php');
require_once(MEMBERS.DS.'comment.php');
require_once(MEMBERS.DS.'picked_stat.php');
require_once(MEMBERS.DS.'log.php');
after is something like:
$member_files = scandir(MEMBERS);
foreach($member_files as $member_file):
require_once(MEMBERS.DS.$member_file);
endforeach;
i havent try the 'after' code though.
is this possible?? or is there any other approach?? or should i just leave it that way (keep adding the lines without scanning the files)
thanks in advance
Consider using Autoloading instead.
With autoloading, you do not have to bother with including files at all. Whenever you instantiate a new class that is not known to PHP at that point, PHP will trigger the registered autoload function. The function includes the required files then. This way, you only load what you need when you need it, which should increase performance.
Simple example with PHP5.3
spl_autoload_register(function($className) {
include "/path/to/lib/and/$className.php";
});
$foo = new Foo;
When you call new Foo, the registered autoload function will try to include the class from /path/to/lib/and/Foo.php. It is advisable to use a classname convention, like f.i. PEAR, to make finding files easier and to cut down on the amount of include_paths.
For additional security and speed, you can provide a more sophisticated Autoloader that uses an array to map from classname to filename, thus making sure only files that actually are part of your application can get included.
Further reading:
http://weierophinney.net/matthew/archives/245-Autoloading-Benchmarks.html
It's possible, but not recommended, like what if somebody could create a php file on that directory, you'll end up including it, besides, you can't predict the inclusion order.
Try this instead:
$includes=array(
'member',
'phone',
'profile',
'talent',
);
foreach($includes as $fname) {
require_once(MEMBERS.DS.$fname. '.php');
}
If you were using classes, consider using autoloading, as #Gordon suggested. And if you werent using classes, consider using them :)
At a first glance your code could work, although you have to ignore "." and ".." in the foreach loop. Plus I'd check, if the file ends with ".php":
$member_files = scandir(MEMBERS.DS);
foreach($member_files as $member_file) {
// Ignore non php files and thus ".." & "."
if (!preg_match('/\.php$/', $member_file) {
continue;
}
require_once(MEMBERS.DS.$member_file);
}
create 2 functions
function GetFiles($directory,$exempt = array('.','..','.ds_store','.svn'),&$files = array()) {
$handle = opendir($directory);
while(false !== ($resource = readdir($handle))){
if(!in_array(strtolower($resource),$exempt)){
if(is_dir($directory.$resource.'/'))
array_merge($files, self::GetFiles($directory.$resource.'/',$exempt,$files));
else
$files[] = $directory.$resource;
}
}
closedir($handle);
return $files;
}
function Autoload($includes = array()){
$files = array();
foreach($includes as $directory)
$files[] = self::GetFiles($directory);
foreach($files as $k=>$v){
foreach($v as $k1=>$v1)
require_once($v1);
}
}
to use it:
$includes = array(
'C:WWW/project/helpers/',
'C:WWW/project/lang/',
'C:WWW/project/lib/',
'C:WWW/project/mod/',
);
Autoload($includes);
