Example #1 TokyoTyrant::fwmKeys() example

<?php$tt = new TokyoTyrant("localhost");/* Create 20 macthing keys */for ($i = 0; $i < 20; $i++) {    $tt->put("key_" . $i, "value_" . $i);}/* Create 20 non-macthing keys */for ($i = 0; $i < 20; $i++) {    $tt->put("something_" . $i, "data_" . $i);}/* Get five matching keys */var_dump($tt->fwmKeys("key_", 5));?>

The above example will output something similar to:

array(5) {
  [0]=>
  string(5) "key_5"
  [1]=>
  string(6) "key_14"
  [2]=>
  string(5) "key_6"
  [3]=>
  string(6) "key_15"
  [4]=>
  string(5) "key_7"
}
