Curious if anyone has a cool snippet or idea for how to accomplish the following:
Code:
/**
 *  Select all of the keys matching a given key.  Asterisks (*)
 *      should be treated as wildcards and would match any string
 *      similar to a regex expression: 'test_*_asdf' => 'test_.+_asdf'
 *
 *  @param string $wild_key
 *  @param array  $array
 *  @return array
 */
array_key_exists_wildcard($wild_key, $array);
Obviously it would be nice to just replace * with .+, but special characters could cause a problem, right? I also couldn't come up with a graceful solution using explode.
