How to prevent PHP variables from being arrays?
- by MJB
I think that (the title) is the problem I am having. I set up a MySQL connection, I read an XML file, and then I insert those values into a table by looping through the elements. The problem is, instead of inserting only 1 record, sometimes I insert 2 or 3 or 4. It seems to depend on the previous values I have read. I think I am reinitializing the variables, but I guess I am missing something -- hopefully something simple.
Here is my code. I originally had about 20 columns, but I shortened the included version to make it easier to read.
$ctr = 0;
$sql = "insert into csd (id,type,nickname,hostname,username,password) ".
"values (?,?,?,?,?,?)";
$cur = $db->prepare($sql);
for ($ctr = 0; $ctr < $expected_count; $ctr++) {
list ( $lbl, $type, $nickname, $hostname, $username, $password) = "";
$bind_vars = array();
$lbl = "csd_{$ctr}";
$type = $ref->itm->csds->$lbl->type;
$nickname = $ref->itm->csds->$lbl->nickname;
$hostname = $ref->itm->csds->$lbl->hostname;
$username = $ref->itm->csds->$lbl->username;
$password = $ref->itm->csds->$lbl->password;
$bind_vars = array($id,$type,$nickname,$hostname,$username,$password);
$res = $db->execute($cur, $bind_vars);
# this is a separate function which works, but which only
# does SELECTS and cannot be the problem. I include it because I
# want to count the total rows.
printf ("%d CSDs on that ITEM now.\n", CountCSDs($id_to_sync));
}
P.S. I also tagged this SimpleXML because that is how I am reading the file, though that code is not included above. It looks like this:
$Ref = simplexml_load_file($file);
