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)); ?>
