在PHP中使用两个数组创建数组

$newArray = array_combine($keysArray, $valuesArray);

$keysArray = array('a', 'b', 'c');
$valuesArray = array(1, 2, 3);
$newArray = array_combine($keysArray, $valuesArray);
print_r($newArray);

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

$keysArray = array('a', 'b', 'c');
$valuesArray = array(1, 2, 3);
$newArray = array();

for ($i = 0; $i < count($keysArray); $i++) {
    $newArray[$keysArray[$i]] = $valuesArray[$i];
}

print_r($newArray);

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