PHP Get all Symlink files?

Question

Is there any way to get all symlinks for specific file?

So let say, I have a file here: home/test/a.png

and I have created 2 symlinks for this file:

home/test-a.png
home/testb/a.png

In this circumstances, is there any function to get those 2 symlinks back?

Something like

get_all_symlinks('home/test/a.png')

which will pass following:

array(
'home/test-a.png',
'home/testb/a.png'
)

Or at least, is there any function or way to get to know if this file has symlink(s) to it?

maybe this will help you http://stackoverflow.com/a/4532279/5440709 — Kanti, Oct 13 '15 at 21:21
Try `readlink()` http://php.net/manual/en/function.readlink.php `var_dump(readlink('home/test/a.png'));` — Twisty, Oct 13 '15 at 21:23
@Twisty no, `readlink` is for symlink. `home/test/a.png` is not a symlink, but actual file. `readlink — Returns the target of a symbolic link` — Codemole, Oct 14 '15 at 05:28
@RayC maybe I misread your question. You did ask *Is there any way to get all symlinks for specific file?* — Twisty, Oct 14 '15 at 15:17

You can use a combination of scandir with is_link and then readlink to create the array. Here are the docs for these functions, http://php.net/manual/en/ref.filesystem.php

It's tricky because symlinks are interpreted as relative pathnames, so you need to determine if the resolved pathname points to the original path. – Barmar Oct 13 '15 at 21:34
