how can I point PHP glob to a specific directory?
提问by Jake
So I got this code to list all jpg images inside a directory but it only works on my root directory and I don't know how to point it to my images directory.
所以我得到了这段代码来列出目录中的所有 jpg 图像，但它只适用于我的根目录，我不知道如何将它指向我的图像目录。
<ul>
<?php foreach (glob("N*T.jpg") as $image): ?>
<li>
<a href="<?php echo str_replace("T", "F", $image); ?>">
<img src="<?php echo "$image"; ?>">
</a>
</li>
<?php endforeach; ?>
</ul>
Can anyone help me with that?
任何人都可以帮助我吗？

This should work:
这应该有效：
glob('images/N*T.jpg');
Otherwise:
除此以外：
chdir('images');
glob('N*T.jpg');

Just prepend the path to the function call.
只需添加函数调用的路径即可。
glob('/path/to/directory/N*T.jpg');
Note that the resulting array will contain the prepended path as well. If you don't want that do
请注意，结果数组也将包含前置路径。如果你不想那样做
array_map('basename', glob('/path/to/directory/N*T.jpg'));

Just add the path to your function call :
只需将路径添加到您的函数调用：
glob("/my/path/to/directory/N*T.jpg")

As understand globstarts with root directory. For example i see image with this
据了解，glob从根目录开始。例如我看到这个图像
<img src="<?php
echo $_SERVER['REQUEST_SCHEME']. '://'. $_SERVER['SERVER_NAME']. '/public_images/logo_image_.gif';
?>"></img>
Then try
然后试试
echo pathinfo( glob( 'public_images/logo_image_.*' )[0] , PATHINFO_EXTENSION). ' <br/>';
and see gif. Location of public_imagesis C:\wamp\www\public_images
并看到gif。的位置public_images是C:\wamp\www\public_images
But for example with
但例如
echo pathinfo( glob( $_SERVER['REQUEST_SCHEME']. '://'. $_SERVER['SERVER_NAME']. 'public_images/logo_image_.*' )[0] , PATHINFO_EXTENSION). ' <br/>';
see Notice: Undefined offset: 0 in C:\wamp\www\show_content.php on line ...
看 Notice: Undefined offset: 0 in C:\wamp\www\show_content.php on line ...
However if from file located at C:\wamp\www\some_dircall file located at C:\wamp\www\public_images, then need to use echo pathinfo( glob( '../public_images/logo_image_.*' )[0] , PATHINFO_EXTENSION)
但是，如果来自文件位于C:\wamp\www\some_dir调用文件位于C:\wamp\www\public_images，则需要使用echo pathinfo( glob( '../public_images/logo_image_.*' )[0] , PATHINFO_EXTENSION)
