exec function doesn't work

Question

I found this code from http://kevin.vanzonneveld.net/techblog/article/convert_anything_to_tree_structures_in_php/, but I couldn't get it work. I am working on WIndow environment and the path I use is /sellable where the sellable is the folder inside the working folder :

if(exec("find /etc/php5", $files)){
    // the $files array now holds the path as it's values,
    // but we also want the paths as keys:
    $key_files = array_combine(array_values($files), array_values($files));

    // show the array
    print_r($key_files);
}

Can anyone help me ?

Iterator seems fine with me .. I manage to get the directory and subdirectory ... But my problem is that, I couldn't get the value of the Iterator object.. I can only print it out on screen.. If I use $file->getFilename() , it print on screen, however is I assign it to var, $file_name = $file->getFilename() , the var value is empty.. Why is that ? — redcoder

Sorry, I have to re-open this question .... I use the RecursiveIteratorIterator which works fine in my local machine Windows as well as Linux on 3rd party server.. Unfortunately, when I move to my client's server (OSCent) , the recursive doesn't works well ...My clients PHP is a Version 5.1.6 .. Could this be the root cause ? — redcoder

In Windows env, I got these results : Array ( [folder1] => folder1 [folder1\folder1.1] => folder1\folder1.1 [folder1\folder1.1\abc.txt] => folder1\folder1.1\abc.txt [folder1\folder1.1\notes.txt] => folder1\folder1.1\notes.txt [folder1\folder1.2] => folder1\folder1.2 [folder1\folder1.2\abc.txt] => folder1\folder1.2\abc.txt [folder1\folder1.2\iphone icard.txt] => folder1\folder1.2\iphone icard.txt [folder1\folder1.2\Logo Saloon Rose House Site.pdf] => folder1\folder1.2\Logo Saloon Rose House Site.pdf — redcoder

You are hardly going to get the find command, nor a /etc/php5 directory on a windows machine. Use PHP's built-in glob or the ~~DirectoryIterator~~ RecursiveDirectoryIterator (Thanks Pascal :) instead. Glob can't iterate through sub-folders natively, but there are simple globr implementations in the User Contributed Notes on the linked page. The iterator can do this natively.

find is a Linux command (an external Linux program).
Which means it will not be present on windows...

And /etc/php5 really looks like an UNIX path to a directory ; and doesn't look like a path to a Windows directory.

So, two problems here :

You have to find an equivalent of... find.
- Maybe using something like cygwin ?
You have to adapt the path, so it fits your system

But I'd say that a PHP-only solution would probably be better : there are functions and classes that will allow you to search files and iterate over the filesystem -- and it would work on both Linux and Windows, not depending on any external program.

For instance, to iterate over a directory, you might want to take a look to the RecursiveDirectoryIterator class -- and maybe also DirectoryIterator.

Hi Martin, I got this from php error log.. [25-Feb-2010 20:23:14] PHP Fatal error: Uncaught exception 'RuntimeException' with message 'DirectoryIterator::__construct(\sellable) [<a href='directoryiterator.--construct'>directoryiterator.--construct</a>]: failed to open dir: No such file or directory' in C:\wamp\www\waterwell\display_e_book.php:21 Stack trace: #0 C:\wamp\www\waterwell\display_e_book.php(21): DirectoryIterator->__construct('\sellable') #1 C:\wamp\www\waterwell\e_book.php(40): include('C:\wamp\www\wat...') #2 {main} thrown in C:\wamp\www\waterwell\display_e_book.php on line 21

DO I have to do anything to use the DirectoryIterator ?

BTW, I use this code : $dir = new DirectoryIterator("/sellable"); foreach ($dir as $file) { if ($file->isDot()) { continue; } echo $file->getFilename() . "\n"; }

@redcoder : like the error message says : "No such file or directory" ;;; which means you are probably not specifying the right path as a parameter when instanciating DirectoryIterator ; I suppose /sellable is not a valid directory ; maybe you have to specify something like C:/Users/.../sellable ; or use a relative path, like '../sellable' ?

redcoder Over a year ago

Yes, your are right martin. I use a wrong directory.. Should be resellable instead of sellable .. That codes is working now .. Thanks ..

i haven't tried it, but "dir /s /b c:\somedir" might work as a quick replacement for "find" on windows. a better (and more portable) solution would be to use the RecursiveDirectoryIterator or php's opendir/readdir functions to recursively list all files in a directory.

see example code here for example: http://php.net/manual/en/function.readdir.php
