The number of items in both arrays $newResponse & $key will always be same.For each item of the $newResponse, i wanted to add items of $key to $newResponse in the same order they exists in $key array as mentioned in the Expected result.How can i achieve that?
dump($newResponse); is an array like below,which am getting as the result of a foreach loop.
array:4 [
0 => array:6 [
"courseId" => 18
"courseDisplayName" => "qqq"
]
1 => array:6 [
"courseId" => 1
"courseDisplayName" => "ips"
]
2 => array:6 [
"courseId" => 18
"courseDisplayName" => "qqq"
]
3 => array:6 [
"courseId" => 1
"courseDisplayName" => "ips"
]
]
dump($key); is an array like below, which is the result of another foreach loop.
array:4[
0=>[
"totalPoints" => 2
"percent" => 1.0
"id" => 2
]
1=> [
"totalPoints" => 10
"percent" => 2
"id" => 3
]
2=> [
"totalPoints" => 4
"percent" => 0.0
"id" => 6
]
3=> [
"totalPoints" => 4
"percent" => 0.0
"id" => 5
]
]
Expected result:
[
[
"courseId" => 18
"courseDisplayName" => "qqq"
"totalPoints" => 2
"percent" => 1.0
"id" => 2
]
[
"courseId" => 1
"courseDisplayName" => "ips"
"totalPoints" => 10
"percent" => 2
"id" => 3
]
[
"courseId" => 18
"courseDisplayName" => "qqq"
"totalPoints" => 4
"percent" => 0.0
"id" => 6
]
[
"courseId" => 1
"courseDisplayName" => "ips"
"totalPoints" => 4
"percent" => 0.0
"id" => 5
]
]
Here's one way to do it:
Assuming your data is:
$newResponse = [
[
"courseId" => 18,
"courseDisplayName" => "qqq"
],
[
"courseId" => 1,
"courseDisplayName" => "ips",
],
[
"courseId" => 18,
"courseDisplayName" => "qqq",
],
[
"courseId" => 1,
"courseDisplayName" => "ips",
]
];
$key = [
[
"totalPoints" => 2,
"percent" => 1.0,
"id" => 2
],
[
"totalPoints" => 10,
"percent" => 2,
"id" => 3
],
[
"totalPoints" => 4,
"percent" => 0.0,
"id" => 6
],
[
"totalPoints" => 4,
"percent" => 0.0,
"id" => 5
]
];
Then I'd probably reach for array_map, having used it for this kind of purpose recently:
$out = [];
array_map(function($a,$b) use (&$out) {
$out[] = $a + $b;
},$newResponse,$key);
print_r($out);
Note in the above the + is very similar to array merge and I believe interchangeable in your use case. You can read about the difference here: Array_merge versus +
