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"
}
