First of all, I am sorry if I sound pretty newby about this, I am actually an UX Researcher, that is currently working on some front-end project that requeres some backend developing. Since there is no backend dev, I have to do it myself.
Currently I am trying to get a specific part of this string in the value:
meta_key: links
meta_value: a:2:{s:3:"url";s:26:"https://YOURLINK.COM/LINKMEHARD";s:5:"title";s:4:"Film";}
What I need to call in php is the value of s:26 (the link). I would have tried to find out that myself, hut I have no idea how that term of the value in the value is called.
