How to convert an array of arrays or objects to an associative array?

Question

I\'m used to perl\'s map() function where the callback can assign both the key and the value, thus creating an associative array where the input was a flat array. I\'m aware of

Answer 1

This is a clarification on my comment in the accepted method. Hopefully easier to read. This is from a WordPress class, thus the $wpdb reference to write data:

class SLPlus_Locations {
    private $dbFields = array('name','address','city');

    public function MakePersistent() {
        global $wpdb;
        $dataArray = array_reduce($this->dbFields,array($this,'mapPropertyToField'));
        $wpdb->insert('wp_store_locator',$dataArray);
    }

    private function mapPropertyToField($result,$property) {
        $result[$property] = $this->$property;
        return $result;
    }
}

Obviously there is a bit more to the complete solution, but the parts relevant to array_reduce() are present. Easier to read and more elegant than a foreach or forcing the issue through array_map() plus a custom insert statement.

Nice!
