PHP Contents of select statement stored in Array and used in Dropdown Menu

I'd like to store the output of an SQL select statement into an array, then use that array to populate a dropdown menu.  

I'm using $result = $sth->fetchAll(); to store the contents of 2 fields into the array. Which comes out looking like this...

Array
(
    [0] => Array
        (
            [id_event_group] => uh
            [0] => uh
            [event_group_desc] => Urban Hope
            [1] => Urban Hope
        )

    [1] => Array
        (
            [id_event_group] => mo
            [0] => mo
            [event_group_desc] => Momentum
            [1] => Momentum
        )

)

Open in new window


When I use the following code to create the dropdown, I just get 'array' 'array' as the options.

echo '<select name="event groups">';
echo '<option value="">Select...</option>';
foreach ($my_array as $k => $v) {
	echo '<option value="' . $k . '">' . $v . '</option>';
}
echo '</select>';

Open in new window


If it helps, here's a link to the page.

Thanks in advance for giving me a hand.

Couple of things needed here.

Try using the PDO::FETCH_ASSOC flag like this: $result = $sth->fetchAll(PDO::FETCH_ASSOC);
The goal is to get only the associative array keys, not the unwanted numeric keys.

Next try the foreach() iterator like this:
echo '<select name="event groups">';
echo '<option value="">Select...</option>';
foreach ($my_array as $sub_array) {
    foreach ($sub_array as $k => $v) {
        echo '<option value="' . $k . '">' . $v . '</option>' . PHP_EOL;
    }
}
echo '</select>';

Open in new window

The goal here is to iterate over the result set with the first foreach() and iterate over each row  of the results set with the second foreach().

I can't test any of this, but I think it's right in principle.

Ray,  Thanks for the help. We're really close.

I updated the page here...

http://testregister.cenational.org/test/test1.php

How can I get the "[id_event_group] => uh" to be the value and the "[event_group_desc] => Urban Hope" to be the description?

Maybe like this?  Still guessing a little since I don't have any way to test, sorry.
echo '<select name="event groups">';
echo '<option value="">Select...</option>';
foreach ($my_array as $sub_array) {
    $k = $sub_array['id_event_group'];
    $v = $sub_array['event_group_desc'];
    echo '<option value="' . $k . '">' . $v . '</option>' . PHP_EOL;
}
echo '</select>';
