Text files, check boxes and exports

Not a walk through as such.
More of a confirmation that it's possible with text files, and a nudge on the right direction of which language I should use.

OK, changed my mind a bit - Anyone out there spot what I've done wrong?



The output is just the word Array



I have a dropdown populated by a text file of values.

When I select 1 or more of these values, and submit, i was hoping to have the selected values sent to a text file. I just get Array



First file:





Please Choose One:
<?php
// define file
$file = '/home/user/hosts.list';

$handle = @fopen($file, 'r');
if ($handle) {
while (!feof($handle)) {
$line = fgets($handle, 4096);
$item = explode('|', $line);
echo '' . $item[0] . '' . "\n";
}
fclose($handle);
}
?>

action.php

<?php
if(isset($_POST['host_id'])) {
$data = $_POST['host_id'] . "\r\n";
$ret = file_put_contents('/home/user/hosts.list.web', $data);
if($ret === false) {
die('There was an error writing this file');
}
else {
echo DONE;
}
}
else {
die('no post data to process');
}
