Question

Array:
$forms = array (

Im trying to get the fields => name to display inside the label. I tried the above but cant get it working, When I echo out $forms_key, I get "0" and "1"

Answer 1

From PHP Manual:
array_keys — Return all the keys or a subset of the keys of an array
You have an array of keys but no associated data as you've stripped this out. Remove array_keys from your first line:
<?php
$forms_keys = $forms['fields'];
foreach ($forms_keys as $forms_key)
{
?>
<div class="form-group col-md-12">
<label for="question3"><?php echo $forms_key['name']; ?></label>
</div>
<?php
}
?>

Answer 2

Your $forms['fields'] array does not have keys, it contains two array elements which contains keys for their inner elements. You can check them with $forms["fields"][0]["name"] or $forms["fields"][1]["name"].

Answer 3

Remove the array_key and set it as below and fields is a sub array. You need to take of it also.
<?php
$forms_keys = $forms['fields'];
for ($i = 0; $i < count($forms_keys); $i++) {
?>
<div class="form-group col-md-12">
<label for="question3"><?php echo $forms_keys[$i]['name']; ?></label>
</div>
<?php
}
?>
