php selecting hash using wildcards
- by tipu
Say I have a hashmap,
$hash = array('fox' => 'some value',
'fort' => 'some value 2',
'fork' => 'some value again);
I am trying to accomplish an autocomplete feature. When the user types 'fo', I would like to retrieve, via ajax, the 3 keys from $hash. When the user types 'for', I would like to only retrieve the keys fort and fork. Is this possible?
What I was thinking was using binary search to isolate the keys with 'f', instead of brute-force searching. Then continue eliminating the indexes as the user types out their query. Is there a more efficient solution to this?
