Why is the following not working. 

$directory = './';
exec('ls -loh ' . $directory, $directory_list);
echo '<ul>';
foreach ($directory_list as $file) {
    $x = explode(' ', $file);
    echo '<li>' . $x[3] . '</li>';
}
echo '</ul>';

If i do not explode and i just do echo '<li>'.$file.'</li>'; then i get a string like this per li drwxr-xr-x 10 user 4.0K Sep 8 16:06 _test

I"m trying to get only the size and not the whole string. What am i doing wrong.

are you splitting your string by double space – Gowri Oct 7 '11 at 4:06
    
I'm using single space. – Pinkie Oct 7 '11 at 4:08

You are aware that PHP has filesystem functions, aren't you – NullUserException Oct 7 '11 at 4:11

If you just want to get the sizes of the file,try this: 

exec("ls -sh ./", $results);
foreach(array_slice($results,1,count($results)) as $file) {
    echo $file . "\n";
}

Here's my output: 

4.0K 24
   0 BookingTest.php
   0 date
4.0K date.php
4.0K exec2.php
4.0K somefile
4.0K file.php
4.0K file

You can also use PHP for that:

$files = glob("./*");
$files = array_combine($files, array_map("filesize", $files));

Which gives you a nice associative array like:

[./curl.php] => 1499
[./db.php] => 10267

Thanks, That works perfectly, but i wanted to know why exec was not working. – Pinkie Oct 7 '11 at 8:47

I wouldn't say that you are doing something wrong - your approach is perfectly acceptable. However, if you want to avoid the explode() you could do something like:

$directory = './';
exec('ls -loh | awk \'{print $4}\'' . $directory, $directory_list);
echo '<ul>';
foreach ($directory_list as $file_size) {
    echo '<li>' . $file_size . '</li>';
}
echo '</ul>';
