Get value of key when building array - php

Question

I have an array that looks like this:
$widgets = array(
'ka' => array(
'name' => 'Kool-Aid',
'active' => true,
'priority' => 10,
'primacy' => 30,
'controller' => 'KoolAid'.$widgets['ka']['settings']['ka_type'].'Widget',
'settings' => array(
'ka_type' => 'BBQ',
),
),
);
If you notice on the row 'controller' I want to put the value of $widgets['ka']['settings']['ka_type'] into the value.
Is there anyway that I can reference the value of a key in an array that I'm currently building?

Answer 1

You can't reference value before it exists. Assign value to temporary variable and then use it in both places.
$kaType = 'BBQ';
$widgets = array(
'ka' => array(
'name' => 'Kool-Aid',
'active' => true,
'priority' => 10,
'primacy' => 30,
'controller' => 'KoolAid'.$kaType.'Widget',
'settings' => array(
'ka_type' => $kaType,
),
),
);

Answer 2

No, but you could assign settings => ka_type => BBQ before controller?

Answer 3

Well if u dont wana save value to variable first then u can do this .
save array on 2 steps.
$widgets = array(
'ka' => array(
'name' => 'Kool-Aid',
'active' => true,
'priority' => 10,
'primacy' => 30,
'controller' => '',
'settings' => array(
'ka_type' => 'BBQ',
),
),
);
$widgets['ka']['controller'] = $widgets['ka']['settings']['ka_type'].'Widget';
OR if there is more than just Ka, u can loop it like
$widgets = array(
'ka' => array(
'name' => 'Kool-Aid',
'active' => true,
'priority' => 10,
'primacy' => 30,
'controller' => '',
'settings' => array(
'ka_type' => 'BBQ',
),
),
);
Foreach($widgets as $name=>$val){
$widget[$wid]['controller'] = $val['settings']['ka_type'].'Widget';
}
Hope it helps
