Question

我想知道如何在我的字符串中出现最后一次并显示之前的内容，例如：

subtree

返回：

$string = "folder\folder2\folder3\folder4\folder5\folder6\archive.anyextensionhere";

我尝试使用explode（explode（“\\”，$ string））但我无法继续。如果有人能帮助我，我会感激。

[UPDATE]

抱歉，我忘了提到我正在使用阵列。

$result = "folder\folder2\folder3\folder4\folder5\folder6";

您可以使用php的函数pathinfo，它将返回数组中所需的全部内容。

使用pathinfo为您提供[dirname], [basename], [extension] and [filename]我相信您要求的所有信息：）

以您的数据为例：

<pre>
    <?php
    $array = array("hacc_snk720\[Hacchi Fansub] Shingeki no Kyojin [BD 720p] + Ovas [Completo]\Episódios [BD 720p]\[Hacchi Fansub]_Shingeki no Kyojin_01 [BD 720p][H264 AAC 8 Bits] [070B7F17].mkv","hacc_snk720\[Hacchi Fansub] Shingeki no Kyojin [BD 720p] + Ovas [Completo]\Episódios [BD 720p]\[Hacchi Fansub]_Shingeki no Kyojin_02 [BD 720p][H264 AAC 8 Bits] [F4746E93].mkv","hacc_snk720\[Hacchi Fansub] Shingeki no Kyojin [BD 720p] + Ovas [Completo]\Ovas [DVD 480p]\[Hacchi Fansub]_Shingeki no Kyojin_OVA 01 [DVD 480p][H264 AAC 8 Bits] [288FC3D3].mkv","hacc_snk720\[Hacchi Fansub] Shingeki no Kyojin [BD 720p] + Ovas [Completo]\Ovas - Kuinaki Sentaku [DVD 480p]\[Hacchi Fansub]_Shingeki no Kyojin - Kuinaki Sentaku_OVA 01 [DVD 480p][H264 AAC 8 Bits] [19570EA3].mkv");

        foreach ($array as $arr) {
            print_r (pathinfo ($arr));
        }
    ?>
</pre>

返回

Answer 2

你可以在字符串上爆炸，然后删除最后一个元素，然后再次内爆：

<?php 
$string = "folder\folder2\folder3\folder4\folder5\folder6\archive.anyextensionhere";
$array = explode('\\', $string);
$file = array_pop($array);
$new_string = implode("\\", $array);

这首先将字符串拆分为数组，然后将数组的最后一个元素放在$file变量中，之后它将删除数组的最后一个元素最后将数组转回字符串

如何获得最后一次出现并显示其余部分？
