创建多维数组的数组 [英] Create an array from multidimensional array

问题描述

我有以下数组：

array (size=2)
  0 => 
    array (size=4)
      0 => string 'http://localhost/wp/wp-content/uploads/2013/03/slider-area.jpg' (length=62)
      1 => int 1584
      2 => int 346
      3 => boolean false
  1 => 
    array (size=4)
      0 => string 'http://localhost/wp/wp-content/uploads/2013/03/featured.jpg' (length=59)
      1 => int 1584
      2 => int 346
      3 => boolean false

我的问题是，我怎么能循环遍历这个数组来生成一个只包含两个值如下一个新的数组：

My Question is that how can I loop through this array to generate a new array that contains only two values as following:

$result_array = array(0 => "http://localhost/wp/wp-content/uploads/2013/03/slider-area.jpg",
                      1 => "http://localhost/wp/wp-content/uploads/2013/03/featured.jpg");

我已经尝试了foreach循环，但无法获得所需的结果数组。我尝试了以下循环：

I have tried a foreach loop but could not get the required result array. I tried the following loop:

foreach ( $array as $key => $value ){

foreach ( $value as $item){

$result_array[] = $item;

}

任何帮助将是非常美联社preciated。

Any help will be highly appreciated.

推荐答案

您已经接近：

$result_array = array(); //Initialization is important.

foreach ($array as $value) {
    $result_array[] = $value[0]; // $value[0] is the first element in the inner array.
}
