A stack is a Last-In-First-Out (LIFO) data structure that allows elements to be pushed and popped. In PHP 7, stacks can be implemented using arrays.
echo print_r(bfs($graph, 'A')); // Array ( [0] => A [1] => B [2] => C [3] => D [4] => E [5] => F ) Before PHP 7, certain data structures were memory hogs
