Question

我有两个多维数组，第一个是索引，其子数组是关联数组。

 Array
 (
[0] => Array
    (
        [layout_id] => 1
        [element_id] => 1
    )

[1] => Array
    (
        [layout_id] => 1
        [element_id] => 2
    )

[2] => Array
    (
        [layout_id] => 1
        [element_id] => 4
    )

[3] => Array
    (
        [layout_id] => 1
        [element_id] => 5
    )

[4] => Array
    (
        [layout_id] => 1
        [element_id] => 6
    )

)

和

  Array
(
  [0] => Array
     (
         [layout_id] => 1
         [element_id] => 1
     )

[1] => Array
    (
        [layout_id] => 1
        [element_id] => 2
    )

[2] => Array
    (
        [layout_id] => 1
        [element_id] => 5
    )

[3] => Array
    (
        [layout_id] => 1
        [element_id] => 8
    )

)

修改预期结果应为

Array
 (
  [0] => Array
      (
        [layout_id] => 1
        [element_id] => 1
    )

[1] => Array
    (
        [layout_id] => 1
        [element_id] => 2
    )

[2] => Array
    (
        [layout_id] => 1
        [element_id] => 5
    )
)

两个阵列的长度可能不同。我想要来自这两个数组的重复条目。在php中有内置函数来执行此操作吗？

谢谢

使用array_uintersect（）来使用自定义比较函数，如下所示：

using (var vw = WebCore.CreateWebView(100,100))
{
    vw.Source = new Uri("website");
    while (vw.IsLoading)
    {
        WebCore.Update();
    }
    var surface = (BitmapSurface)vw.Surface;
    surface.SaveToPNG("screen1.png");
    surface.Resized += (s, e) =>
    {
        // Save the updated buffer to a new PNG image.
        surface.SaveToPNG("screen2.png");
        WebCore.Shutdown();
    };

    var x = vw.ExecuteJavascriptWithResult("document.body.scrollWidth").ToString();
    var y = vw.ExecuteJavascriptWithResult("document.body.scrollHeight").ToString();
    vw.Resize(Convert.ToInt32(x), Convert.ToInt32(y));

    WebCore.Run();
}

如果customCompare返回0，则表示$ val1和$ val2相等。

PHP与多维索引关联数组相交
