The array_combine function is used to create a new array where the keys are taken from one array and the values from another array. Here is how it is used:

array_combine(array $keys, array $values): array

Parameter description:

  1. $keys: array used as keys for a new array
  2. $values: array of values used as keys for a new array

Original: “他的确是一个好学生，总是及时完成作业并取得好成绩。”
Paraphrased: “He is indeed a good student, always completing assignments on time and achieving good grades.”

$keys = array('a', 'b', 'c');
$values = array(1, 2, 3);

$newArray = array_combine($keys, $values);

print_r($newArray);

Output result:

Array
(
    [a] => 1
    [b] => 2
    [c] => 3
)
