The problem is that this line:
$rpm_list = `rpm -qa`;
gives back a string, so use this:
$rpm_list = `rpm -qa`;
$rpm_list = explode("\n", $rpm_list);
and see how that goes

Subject: [PHP] splitting up an array into lines ...
I want this code to work thru a large cluster and put the rpm information
into a db ,
it all works apart from the foreach loop.
why doesnt my code work ( in particular the foreach loop ) ,
// get hostname
$host = `hostname`;
// get a list of rpms
$rpm_list = `rpm -qa`;
// open a db connection and insert them into the db
include "db.php";
print "working on host : $host\n";
$test = mysql_query ("SELECT * FROM machine_info WHERE host = '$host'");
$test1 = mysql_fetch_object ($test);
print "TEST: $test1->host\n";
if ($test1->host == "")
{
print "machine doesnt exists in the db , adding an entry for
$host\n";
$add_machine_to_table = mysql_query("INSERT INTO machine_info (host)
VALUES ('$host')");
}
// get the rpm list a line at a time
foreach($rpm_list as $rpm)
{
$query = "UPDATE machine_info SET rpm = '$rpm' WHERE host =
'$host'";
if (!(mysql_query($query)))
{
print "Mysql could not do the update query - for host
$host";
}
}
------------
i get :
X-Powered-By: PHP/4.0.6
Content-type: text/html
working on host : lxplus038
TEST: lxplus038

<b>Warning</b>: Invalid argument supplied for foreach() in <b>
