php arrays

The following:

$columns = array();
foreach($form as $f)
{
$columns += array($f['form_field_id'] => $f['label']);
}

Will create.

Array
(
[] =>
[J] => J
[1] => Title
[3] => Recruiter
[2] => Description
[4] => Job_Type
[5] => Segment
[6] => Owner
)


And this will create:

$columns = array();
foreach($form as $f)
{
$columns[] = array($f['form_field_id'] => $f['label']);
}
