How to prevent PHP variables from being arrays or objects?
- 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; $ctr++) {
unset($bind_vars,$dat);
$lbl = "csd_{$ctr}";
$dat['type'] = (string) $ref->itm->csds->$lbl->type;
$dat['nickname'] = (string) $ref->itm->csds->$lbl->nickname;
$dat['hostname'] = (string) $ref->itm->csds->$lbl->hostname;
$dat['username'] = (string) $ref->itm->csds->$lbl->username;
$dat['password'] = (string) $ref->itm->csds->$lbl->password;
$bind_vars = array( $id,$dat['$type'], $dat['$nickname'], $dat['$hostname'],
$dat['$username'], $dat['$password']);
print_r ($bind_vars);
$res = $db->execute($cur, $bind_vars);
}
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);
UPDATE: I've changed the code around as per suggestions, and now it is not always the same pattern, but it is equally broken. When I display the bind array before inserting, it looks like this. Note that I also count the rows before and after, so there are 0 rows, then I insert 1, then there are 2:
