Newbie in need of assistance

[Anon]

Hey folks,

I'm in need of a little help. I'm new to PHP and have hit kind of a road block. I would like to take a query submitted by a webpage, and do a DiG on it, put the contents of the results into an array, and then using foreach(), print each line of the array to a web page. Heres the code I have:

<?
$digarray = /usr/local/bin/dig mx $query

    foreach ($digarray as $result) {
            print("$result<br>\n")
            }

?>

Yet everytime I run it in a browser, I get:

Warning: Invalid argument supplied for foreach() in /usr/local/apache/htdocs/mxdig-results.php on line 15

Can anyone help me out with this? Its driving me up the wall!!! 🙂 Thanks!

Try putting a semicolon after your variable declaration and your print statement. I'm not up on DiG so I don't know what it does, but you do need the semicolons:

<?
$digarray = /usr/local/bin/dig mx $query;

foreach ($digarray as $result) {
print("$result<br>\n");
}
?>

Don't know if this will help or not.
