I have these two arrays and I want to combine them into one. Using the duplicate values from 0,1 in the second array. Below is an example of how I would want it to look. I hope someone can help.
Array(
[201500001] => Array
(
[0] => 1003123603
[1] => 3062226597
)
[201500002] => Array
(
[0] => 3067005512
)
)
Array(
[1127893457] => Array
(
[0] => 1003123603
[1] =>
)
[1127893467] => Array
(
[0] => 1003133106
[1] => 3067005512
)
[1127893443] => Array
(
[0] => 1004146393
[1] => 3062226597
)
[1127893246] => Array
(
[0] => 1003154423
[1] => 5149282937
)
)
Expected output:
Array(
[1127893457] => Array
(
[0] => 1003123603
[1] =>
[2] => 201500001
)
[1127893467] => Array
(
[0] => 1003133106
[1] => 3067005512
[2] => 201500002
)
[1127893443] => Array
(
[0] => 1004146393
[1] => 3062226597
[2] => 201500001
)
[1127893246] => Array
(
[0] => 1003154423
[1] => 5149282937
[2] =>
)
)

Answer 1

I rewrote your various arrays as valid arrays. Other than that, I think that what you are looking for is to use array_intersect. This works for me:
$source = array(
201500001 => array(
0 => 1003123603,
1 => 3062226597
),
201500002 => array(
0 => 3067005512
)
);
$target = array(
1127893457 => array(
0 => 1003123603
),
1127893467 => array(
0 => 1003133106,
1 => 3067005512
),
1127893443 => array(
0 => 1004146393,
1 => 3062226597
),
1127893246 => array(
0 => 1003154423,
1 => 5149282937
)
);
$expected = array(
1127893457 => array(
0 => 1003123603,
2 => 201500001
),
1127893467 => array(
0 => 1003133106,
1 => 3067005512,
2 => 201500002
),
1127893443 => array(
0 => 1004146393,
1 => 3062226597,
2 => 201500001
),
1127893246 => array(
0 => 1003154423,
1 => 5149282937
)
);
$newArray = [];
foreach ($target as $targetKey => $targetValue) {
foreach ($source as $sourceKey => $sourceValue) {
if (array_intersect($sourceValue, $targetValue)) {
$targetValue[2] = $sourceKey;
}
$newArray[$targetKey] = $targetValue;
}
}
echo ($newArray === $expected) ? "Match!" : "Miss." . PHP_EOL;

Merges the elements of one or more arrays together so that the values of one are appended to the end of the previous one. It returns the resulting array.
<?php
$array1 = array("color" => "red", 2, 4);
$array2 = array("a", "b", "color" => "green", "shape" => "trapezoid", 4);
$result = array_merge($array1, $array2);
print_r($result);
?>
