Question

I have multiple arrays (which are all results from a MySQL database using a PDO statement), here is one as an example:

Array ( [id] => 1 [0] => 1 [name] => HELLO [1] => HELLO )

I only want the keys which are not numbers (in this case ‘id’ and ‘name’) as the array.

How can I filter out the keys which are integers so that I can end up with an array which will be:

Array ( [id] => 1 [name] => HELLO )

(The keys aren’t always going to be ‘id’ and ‘name’, or the name numbers, or the same number of array keys)

Answer 1

I think you should solve this problem fetching row with appropriate flag PDO::FETCH_ASSOC

$sth = $dbh->prepare("SELECT id,name FROM tableName");
$sth->execute();

$row = $sth->fetch(PDO::FETCH_ASSOC); // use this flag for return only column names

If it’s not possible:

foreach($array as $k=>$v) {
    if(filter_var(FILTER_VALIDATE_INT, $k) !== FALSE) {
        unset($array[$k]);
    }
}
