如何在两个“ /”字符之间查找字符串-PHP

Question

What I'm trying to do is edit the value of a folder when the title is changed. The title is directly associated with the folder and as such, for consistency, the folder needs to be updates.

What I have pre-stored so far is:

Pictures/Title/image.png

What i want to do is get out "Title" which will always be between two / characters. Then take that out of the string and replace it with the new title.

preg_match is the obvious function, but i'm unsure of how to use it to find and return the string I want.

preg_match("$title" , $ImageLocation, $matches);
$title = $matches

Ideally, that would work if i knew what the title would be but I can't figure out how to both account for the unknown string, and for the special characters.

All i know for certain is that "title", whatever that may be, will be between two "/" characters. The php docs show the use of special characters but i personally cannot fathom how to use the commands as it doesn't appear to be specific. Any help's appreciated.

As long as the folder structure remains the same, you can avoid Regexes and do

<?php
$title="Pictures/Anything/image.png";
$parts=explode("/",$title);
echo $parts[1];                          //Anything
