How to compare values ​​for similarity in arrays in PHP?

Question

PHP

Hello. For example. There are 2 arrays (or there may be more).
Each of them has meanings (conventional names for something). For example:

Array 1
[0]
Name: Vladimir
[1]
Name: Alex

Array 2
[0]
Name: Maxim
[1]
Name: Alex

OBJECTIVE:
Calculate similar values ​​in arrays. Using for example the similar_text function. And so that it would be possible to work with array values ​​1, 2. I.e. I need to further create one array, for example:
Array Alex

And here I can insert values ​​from array 2
