范例
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));?>
以上例程的输出类似于:
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" }
