从包含的脚本运行glob（）返回空数组 [英] Running glob() from an included script returns empty array

问题描述

也许我在某处忽略了一些小错误，但是我花了20分钟盯着这个并重新阅读PHP手册，这对于我来说花费太长时间才能花费在一行代码上。

Perhaps I'm over-looking some minor error somewhere, however I have spent 20 minutes staring at this and re-reading the PHP manual, which is far too long for me to spend on a single line of code.

我正在编写一个WordPress插件，它是作为一个类实现的。在我的插件中，我有以下几行：

I am writing a WordPress plugin which is implemented as a class. In my plugin I have the following line:

$choices = glob(dirname(__FILE__)."/images/*.{gif,jpg,jpeg,png}", GLOB_BRACE);

显然我希望 $ choices 成为一个包含相对于包含文件的images文件夹中每个图像的数组。该行最初看起来像这样：

Clearly I want $choices to be an array containing every image in the "images" folder, relative to the included file. The line originally looked like this:

$choices = glob("images/*.{gif,jpg,jpeg,png}", GLOB_BRACE);

然而，它返回的数组包含来自完全不同文件夹的多个图像（ wp-admin / images 文件夹，具体而言）。我最好的选择是，因为调用 glob（）的函数本身是由 admin_init 钩子调用的，这是由 wp-admin 文件夹中的脚本调用。为了进行相对于我的插件而不是 wp-admin 文件夹的搜索，我应用了 dirname（__ FILE __）在开头。

However it was returning an array with several images from an entirely different folder (the wp-admin/images folder, to be specific). My best bet is that it's because the function which calls glob() was itself called by the admin_init hook, which is called by a script in the wp-admin folder. In order to make the search relative to my plugin and not the wp-admin folder I applied the dirname(__FILE__) at the beginning.

我现在的问题是我得到一个空数组。我甚至尝试过：

My issue now is that I'm getting an empty array. I even tried:

var_dump(dirname(__FILE__)."/images/*.{gif,jpg,jpeg,png}");

查看确切传递的内容。返回以下内容：

to see exactly what was getting passed. The following was returned:

string（79）/ home / coupon / public_html / wp-content / plugins / DE-menu / images / *。{gif，jpg，jpeg，png}

string(79) "/home/coupon/public_html/wp-content/plugins/DE-menu/images/*.{gif,jpg,jpeg,png}"

这对我来说很好......正如我所说，也许我看起来很简单。有没有想法？

Which looks just fine to me... As I said, perhaps I'm over-looking something simple. Anyone have any ideas?
