数组拼接数组

Question

我有数组的数组：

Array
(
   [0] => "title"
   [1] => Array
         (
             [0] => a
             [1] => b
             [2] => c
         )
   [2] => Array
         (
             [0] => d
             [1] => e
             [2] => f
         )
)

我需要将一个数组插入到第一个数组中，如下所示

Array
(
   [0] => "title"
   [1] => Array
         (
             [0] => a
             [1] => b
             [2] => c
         )
   [2] => Array
         (
             [0] => a1
             [1] => b1
             [2] => c1
         )
   [3] => Array
         (
             [0] => d
             [1] => e
             [2] => f
         )
)

我不知道如何使用array_splice()。我试过这种方法，但不起作用。

array_splice($main_array, 2, 0 $array_to_insert)

Answer 1

$main_array = array(0 => "title",1 => array("a","b"));

$array_to_insert = array("c","d");

$new_array = array_splice($main_array, 1, 0, array($array_to_insert));

print_r($main_array);

Answer 2

更新:在阅读评论之后，这似乎是一个javascript问题。:) ??!!.为了完整起见，这是一个PHP解决方案--按照要求;)

array_splice()是正确的方法。使用以下代码：

<?php

$arr = array (
 'title',
 array('a', 'b', 'c'),
 array('d', 'e', 'f')
);
var_dump($arr);

// note that I've wrapped the array to be inserted into another, empty, array
array_splice($arr, 2, 0, array(array('a1', 'b1', 'c1')));

// further note that array_splice will not return the new array. $arr is
// passed by reference and will get modified from inside of array_splice
var_dump($arr);

我想这会帮助你..。

    var a = [1,2,3,4,5];
a.splice(2,0,'a','b');  // Returns []; a is [1,2,'a','b',3,4,5]
a.splice(2,2,[1,2],3);  // Returns ['a','b']; a is [1,2,[1,2],3,3,4,5]
