PHP中数组合并 追加数组例子

$fruits = array("apple","banana","pear");
$numbered = array("1","2","3");
$cards = array_merge($fruits, $numbered);
print_r($cards);
// 输出结果：
// Array ( [0] => apple [1] => banana [2] => pear [3] => 1 [4] => 2 [5] => 3 )
?>

$fruit1 = array("apple" => "red", "banana" => "yellow");
$fruit2 = array("pear" => "yellow", "apple" => "green");
$result = array_merge_recursive($fruit1, $fruit2);
print_r($result);
// 输出结果：
// Array ( [apple] => Array ( [0] => red [1] => green ) [banana] => yellow [pear] => yellow )
?>

$fruits = array("Apple", "Banana", "Orange", "Pear", "Grape", "Lemon", "Watermelon");
$subset = array_splice($fruits, 4);
print_r($fruits);
print_r($subset);
// 输出结果为：
// Array ( [0] => Apple [1] => Banana [2] => Orange [3] => Pear )
// Array ( [0] => Grape [1] => Lemon [2] => Watermelon )
?>

$fruits = array("Apple", "Banana", "Orange", "Pear", "Grape", "Lemon", "Watermelon");
$subset = array_splice($fruits, 2, -1, array("Green Apple", "Red Apple"));
print_r($fruits);
print_r($subset);
// 输出结果：
// Array ( [0] => Apple [1] => Banana [2] => Green Apple [3] => Red Apple [4] => Watermelon )
// Array ( [0] => Orange [1] => Pear [2] => Grape [3] => Lemon )
?>
