The fastest way to search for a cached value, to find if there is a cycle in your data, to see if a
given program state has occurred before, to see whether a value is in a set and then adding it, and
for so many similar tasks, is just to do an array dereference:
$Key=$SomeStateString1.'|'.$SomeStateString2; // State can have multiple substates
if (@$StateSet[$Key]) // or use isset()
; // The key already exists: do optional processing here
else
; // The key does not yet exist: do optional processing here
$StateSet[$Key]=1; // Store state existence (or store associated data values)
