在fo​​reach循环解封数组值 [英] Unsetting array values in a foreach loop

问题描述

我有一个foreach循环设置要经过我的数组，检查是否有一定的联系，如果发现它会从数组链接。

我的code：

 的foreach（$图像，图像$）
{
    如果（$形象=='http://i27.tinypic.com/29yk345.gif'||
    $图像=='http://img3.abload.de/img/10nx2340fhco.gif'||
    $图像=='http://i42.tinypic.com/9pp2456x.gif'）
    {
        未设置（$图像[$图片]）;
    }
}
 

但它不会删除阵列entires。这可能是与 $图像[$图片] ，因为这不是数组项，只有内容的钥匙吗？有没有办法做到这一点不纳入反？

感谢。

编辑：感谢球员，但现在我有一个问题，其中数组项实际上没有被删除

我的新code：

 的foreach（$图像[1] $关键=＆GT; $图）
{
    如果（$形象=='http://i27.tinypic.com/29yk345.gif'）
    $图像=='http://img3.abload.de/img/10nx2340fhco.gif'||
    $图像=='http://i42.tinypic.com/9pp2456x.gif'）
    {
        未设置（$图像[$关键]）;
    }
}
 

$图像是一个actuallty二维数组所以现在我为什么需要$图像[1]。我已经确认并成功地绕着数组元素，有些元素也确实有一些，我想删除这些网址，但他们没有被清除。这是我的 $图像数组：

 阵列
（
    [0] =＆GT;排列
        （
            [0] =＆GT;无用
            [1] =＆GT;无用
            [2] =＆GT;无用
            [3] =＆GT;无用
            [4] =＆GT;无用
        ）    [1] =＆GT;排列
        （
            [0] =＆GT; http://i27.tinypic.com/29yk345.gif
            [1] =＆GT; http://img3.abload.de/img/10nx2340fhco.gif
            [2] =＆GT; http://img3.abload.de/img/10nx2340fhco.gif
            [3] =＆GT; http://i42.tinypic.com/9pp2456x.gif
        ））
 

谢谢！

解决方案

 的foreach（$图像，$关键=＆GT; $图）
{
    如果（in_array（$形象，阵列（
       http://i27.tinypic.com/29ykt1f.gif'，
       http://img3.abload.de/img/10nxjl0fhco.gif'，
       http://i42.tinypic.com/9pp2tx.gif'，
    ））
    {
        未设置（$图像[$关键]）;
    }
}
 

I have a foreach loop set up to go through my array, check for a certain link, and if it finds it removes that link from the array.

My code:

foreach($images as $image)
{
    if($image == 'http://i27.tinypic.com/29yk345.gif' ||
    $image == 'http://img3.abload.de/img/10nx2340fhco.gif' ||
    $image == 'http://i42.tinypic.com/9pp2456x.gif')
    {
        unset($images[$image]);
    }
}

But it doesn't remove the array entires. It's probably something to do with $images[$image], as that's not the key of the array entry, only the content? Is there a way to do this without incorporating a counter?

Thanks.

EDIT: Thanks guys, but now I have another problem where the array entries don't actually get deleted.

My new code:

foreach($images[1] as $key => $image)
{
    if($image == 'http://i27.tinypic.com/29yk345.gif')
    $image == 'http://img3.abload.de/img/10nx2340fhco.gif' ||
    $image == 'http://i42.tinypic.com/9pp2456x.gif')
    {
        unset($images[$key]);
    }
}

$images is actuallty a two-dimensional array now hence why I need $images[1]. I have checked and it successfully goes around the array elements, and some elements do actually have some of those URLs in that I wish to delete, but they're not getting deleted. This is my $images array:

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

    [1] => Array
        (
            [0] => http://i27.tinypic.com/29yk345.gif
            [1] => http://img3.abload.de/img/10nx2340fhco.gif
            [2] => http://img3.abload.de/img/10nx2340fhco.gif
            [3] => http://i42.tinypic.com/9pp2456x.gif
        )

)

Thanks!

解决方案

foreach($images as $key => $image)
{
    if(in_array($image, array(
       'http://i27.tinypic.com/29ykt1f.gif',
       'http://img3.abload.de/img/10nxjl0fhco.gif',
       'http://i42.tinypic.com/9pp2tx.gif',
    ))
    {
        unset($images[$key]);
    }
}
