merge 2 php arrays which aren't of the same length by value
- by Iain Urquhart
Excuse me if this has indeed been asked before, I couldn't see anything that fitted my needs out of the dozens of similar titled posts out there ;)
I'm trying to merge 2 php arrays which aren't of the same length, and merge them on a value that exists from identical key = values within both arrays.
My first query produces an array from a nested set:
array
(
1 => array
(
'node_id' => 1,
'lft' => 1,
'rgt' => 4,
'moved' => 0,
'label' => 'Home',
'entry_id' => 1,
'template_path' => '',
'custom_url' => '/',
'extra' => '',
'childs' => 1,
'level' => 0,
'lower' => 0,
'upper' => 0
),
2 => array
(
'node_id' => 2,
'lft' => 2,
'rgt' => 3,
'moved' => 0,
'label' => 'Home',
'entry_id' => NULL,
'template_path' => '',
'custom_url' => 'http://google.com/',
'extra' => '',
'childs' => 0,
'level' => 1,
'lower' => 0,
'upper' => 0
)
);
My second array returns some additional key/values I'd like to insert to the above array:
array
(
'entry_id' => 1,
'entry_title' => 'This is my title',
);
I want to merge both of the arrays inserting the additional information into those that match on the key 'entry_id', as well as keeping the sub arrays which don't match.
So, by combining the two arrays, I'd end up with
array
(
1 => array
(
'node_id' => 1,
'lft' => 1,
'rgt' => 4,
'moved' => 0,
'label' => 'Home',
'entry_id' => 1,
'template_path' => '',
'custom_url' => '/',
'extra' => '',
'childs' => 1,
'level' => 0,
'lower' => 0,
'upper' => 0,
'entry_title' => 'This is my title'
),
2 => array
(
'node_id' => 2,
'lft' => 2,
'rgt' => 3,
'moved' => 0,
'label' => 'Home',
'entry_id' => NULL,
'template_path' => '',
'custom_url' => 'http://google.com/',
'extra' => '',
'childs' => 0,
'level' => 1,
'lower' => 0,
'upper' => 0,
'entry_title' => NULL
)
);
Actually, writing this out makes me think I should do it via sql...
Any help/advice greatly appreciated...
