Example #1 TokyoTyrant::fwmKeys() example

  <?php

$tt  = new  TokyoTyrant ( "localhost" );

 
 for ( $i  =  0 ;  $i  <  20 ;  $i ++) {
     $tt -> put ( "key_"  .  $i ,  "value_"  .  $i );
}

 
 for ( $i  =  0 ;  $i  <  20 ;  $i ++) {
     $tt -> put ( "something_"  .  $i ,  "data_"  .  $i );
}

 
 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"
}
