查找与目录名称匹配的目录路径（递归）

Question

I have the following directory structure:

/mnt/disk/documents
/mnt/disk/data/files/
/mnt/disk/data/morefiles/

The mount point disk/ is variable. I need to get all files from data/ and it's sub directories. I know how to list files with glob but in this case I need first find the directory data and than all files recursively.

How can I do that, not knowing the full path from the beginning?

Answer 1

One way.

realpath ( string $path );

realpath() expands all symbolic links and resolves references to '/./', '/../' and extra '/' characters in the input path and returns the canonicalized absolute pathname.

Example:

PHP:

 <?php
    echo realpath('/windows/system32');

    echo realpath('C:\Program Files\\');
    ?>

Result:

C:\WINDOWS\System32
C:\Program Files

Simple way. Any questions, just ask that I will try to answer.
