PHP从两个数组创建关联数组

$array1 = array('a', 'b', 'c');
$array2 = array(1, 2, 3);
$combinedArray = array_combine($array1, $array2);
print_r($combinedArray);

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

$array1 = array('a', 'b', 'c');
$array2 = array(1, 2, 3);
$combinedArray = array();
for ($i = 0; $i < count($array1); $i++) {
    $combinedArray[$array1[$i]] = $array2[$i];
}
print_r($combinedArray);

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