/*
* Class for array search in php using wild card, case sensitive, exact word match.
*
* When it comes to array search in php by exact key or value or wild card search and multidimensional
* associative array search recursively , php developers doesn't have much choice by default but to write
* your own custom code to fulfill that. For this, they may have to resort to using many functions like
* in_array, array_search, php foreeach loop, php substr and lots of other functions but none of them
* come handy when you need advanced associative multidimensional array search in php for keys and values.
* Sometimes php developers may have connect to sql database repeatedly and issue sql query repeatedly
* to find required records. But after using this class, they can simply fetch all records at once
* and then filter required records using advanced php array search class.
* Here are key benefits:
* Search multidimensional associative array in php using wild card '%'. You can find any keys or values
* of an array which starts or ends which some phrase or exact phrase you would like to search for.
* This means:
* 1. Search array in php recursively by key only using exact phrase or wild card %
* 2. Search array in php recursively by value only using exact phrase or wild card %
* 3. Search array in php recursively by values or keys using exact phrase or wild card %
* 4. Search array in php recursively - case sensitive and insensitive search
