I've been playing with this all day and haven't figured out a good way to do it...
I have two arrays and am trying to create an array based on matching values.
//$original
Array
(
[0] => Array
(
[items] => Array
(
[0] => Array
(
[0] => PA
[1] => DZ
[2] => ER
[3] => TY
)
开发者_运维知识库 [1] => Array
(
[0] => KV
[1] => EN
[2] => CR
)
[2] => Array
(
[0] => HU
[1] => GO
[2] => GA
[3] => FI
)
)
)
)
//$compare
Array
(
[0] => Array
(
[items] => Array
(
[0] => Array
(
[0] => PA
[1] => AN
[2] => ER
)
[1] => Array
(
[0] => KV
)
[2] => Array
(
[0] => HU
[1] => XV
[2] => ZL
[3] => FI
)
)
)
)
And I'm trying to produce
//$similar
Array
(
[0] => Array
(
[items] => Array
(
[0] => Array
(
[0] => PA
[2] => ER
)
[1] => Array
(
[0] => KV
)
[2] => Array
(
[0] => HU
[3] => FI
)
)
)
)
Use array_intersect
.
$similar = $compare;
$similar[0]['items'] = array_intersect($compare[0]['items'], $original[0]['items']);
