I found a way to solve my problem, but I want to see if there is any better or clear solution for this. I have two associative arrays like this:
$person= [
"A" => [
"sur" => "a",
"fir" => "andras"
],
"C" => [
"sur" => "b",
"fir" => "balint"
]
];
$data = [
"A" => ["011", "012", "013"],
"C" => ["021", "022"]
];
I want to map the two arrays if their keys are equal. So the result should look like this:
$person= [
"A" => [
"sur" => "a",
"fir" => "andras",
"tel" => ["011", "012", "013"]
],
"C" => [
"sur" => "b",
"fir" => "balint",
"tel" => ["021", "022"]
]
];
My code:
foreach ( array_intersect_key(array_keys($data,$person)) as $id) {
$person[$id]['tel'] = $data[$id];
}
