How to search by key=>value in a multidimensional array in PHP ?
In PHP, multidimensional array search refers to searching a key=>value in a multilevel nested array. This search can be done either by the iterative or recursive approach.
Recursive Approach: Check if the key exists in a multidimensional array and the value of a key is equal to required one then the result stored in an array and also recur through each element.

101 - AMIT
202 - AMIT
