Question

我有这种情况

$array2 = array();

    for($i=1;$i<=3;$i++){
        $key_page_number = $key."?page=".$i;
        $key_page_number = $this->get_page_with_check_error($key_page_number);
        preg_match_all("~<div class=\"desc-zone\">\s*<a\sitemprop=\"url\"\shref=\"(.*?)\"~", $key_page_number, $product_urls);  
        $array2[] = $product_urls[1];
        }

我的array2看起来像这样

[1] => Array(
  [0] => something
  [1] => something
)
[2] => Array(
  [0] => something
  [1] => something
)
[3] => Array(
  [0] => something
  [1] => something
)

我想让我的array2看起来像这样

[1] => Array(
  [0] => something
  [1] => something
  [2] => something
  [3] => something
  [4] => something
  [5] => something
)

我如何合并数组的这个元素？

<?php

$data = 
[
    [
        'foo',
    ],
    [
        'bar'
    ]
];

$first_key       = array_keys($data)[0];
$out[$first_key] = array_merge(...$data);
var_export($out);

输出：

array (
    0 => 
    array (
      0 => 'foo',
      1 => 'bar',
    ),
  )
