Question

I have an array generated by PHP

array(
  array(
  'name'=>'node1',
  'id' => '4'
   ),
  array(
  'name'=>'node2'
  'id'=>'7'
  )
)

And I am trying to add an array to a specific id (so let’s say id 4)

'children'=>
        array(
          array('name'=>'node2','id'=>'5'),
          array('name'=>'node3','id'=>'6')
        )

So then it would look like

array(
  array(
  'name'=>'node1',
  'id' => '4'
  'children'=>
        array(
          array('name'=>'node2','id'=>'5'),
          array('name'=>'node3','id'=>'6')
        )
   ),
  array(
  'name'=>'node2'
  'id'=>'7'
  )
)

but I can’t seem to figure out a way to search a multidimensional array, and add a multidimensional array to that array.

Any help?

Use a foreach loop to iterate through the array (making sure to get the key too), check the value, add if needed and break when found.

foreach($array as $k=>$v) {
    if( $v['id'] == 4) {
        $array[$k]['children'] = array(...);
        break;
    }
}
