Make an element in array explode - php

Question

How to make an element array inside an array explode again.
I have an array like this
echo "<pre>";
print_r($pks);
The Result.
Array
(
[0] => 2017-04-15||KMTC_HOCHIMINH
[1] => 2017-04-15||OOCL_NAGOYA
)
I expected like this,
Array
(
[record] =>
[1] 2017-04-15
[2] KMTC_HOCHIMINH
[record] =>
[1] 2017-04-15
[2] OOCL_NAGOYA
)
What keys on php to process array like this.
Please advise.
UPDATE
How about this .
Array
(
[0] => Array
(
[date] => 2017-04-15
[vessel] => KMTC_HOCHIMINH
)
[1] => Array
(
[date] => 2017-04-15
[vessel] => OOCL_NAGOYA
)
)

Answer 1

Try this, check the live demo
foreach($pks as $k => $v) {
$values = explode('||', $v);
$result[] = array_combine(range(1, count($values)), $values);
//added
$res[] = array_combine(['date', 'vessel'], $values) ;
}
result
Array
(
[0] => Array
(
[1] => 2017-04-15
[2] => KMTC_HOCHIMINH
)
[1] => Array
(
[1] => 2017-04-15
[2] => OOCL_NAGOYA
)
)

Answer 2

You can use array_walk() (or just foreach if you want):
array_walk($pks, function(&$a) {
$a = array_combine(['date', 'vessel'], explode('||', $a));
});
Foreach method:
foreach($pks as $k => $v) {
$pks[$k] = array_combine(['date', 'vessel'], explode('||', $v));
}
However, the key of each array won't be record, since it's impossible to have the same key multiple times.
Output:
Array
(
[0] => Array
(
[date] => 2017-04-15
[vessel] => KMTC_HOCHIMINH
)
[1] => Array
(
[date] => 2017-04-15
[vessel] => OOCL_NAGOYA
)
)
Bonus method because I like messing with arrays:
$pks = array_map('explode', array_fill(0, count($pks), '||'), $pks);
