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

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