根据值从数组创建一个数组，并将匹配项包含在数组中

Question

I'm wanting to group my data by a specific value (parent name) and then merge all the items that share the same parent name under a "items" array

However it's overwriting the items array, not adding to it, so for example "items" in the output should have multiple items not just one.

Any ideas?

$result = array();
foreach ($page->products_codes as $option) {
    $result[$option->parent->name]["title"] = $option->parent->title;
    $result[$option->parent->name]["items"] = $option->title;
}

Outputs as:

array (
  'fixture' => 
  array (
    'title' => 'Fixture',
    'items' => 'Pinhole90 Fixed with LED51',
  ),
  'finish' => 
  array (
    'title' => 'Finish',
    'items' => 'RAL',
  ),
  'ip-rating' => 
  array (
    'title' => 'IP Rating',
    'items' => 'IP54',
  ),
  'emergency' => 
  array (
    'title' => 'Emergency',
    'items' => 'Maintained 3hr Self Test',
  ),
  'installation' => 
  array (
    'title' => 'Installation',
    'items' => 'Plaster-kit for seamless flush appearance',
  ),
  'led' => 
  array (
    'title' => 'LED',
    'items' => 'LED50 ONE',
  ),
  'cct' => 
  array (
    'title' => 'CCT',
    'items' => '90 CRI 4000K',
  ),
  'beam-angle' => 
  array (
    'title' => 'Beam Angle',
    'items' => '38°',
  ),
  'protocol' => 
  array (
    'title' => 'Protocol',
    'items' => 'Bluetooth',
  ),
  'louvre-lens' => 
  array (
    'title' => 'Louvre/Lens',
    'items' => 'Heavy Spread Lens',
  ),
)

Any thoughts?

Based on the preferred data structure you specified:

$result = array();
foreach ($page->products_codes as $option) {
    $result[$option->parent->name]["title"] = $option->parent->title;
    $result[$option->parent->name]["items"][] = $option;
}

$result = array_values($result);
