Example #1 QuickHashIntStringHash::update() example
<?php
$hash -> add ( 161803398 , "--" );
$hash -> add ( 314159265 , "a lot" );
echo $hash -> get ( 161803398 ), "\n" ;
echo $hash -> get ( 314159265 ), "\n" ;
var_dump ( $hash -> update ( 314159265 , "a lot plus one" ) );
var_dump ( $hash -> update ( 314159999 , "a lot plus one" ) );
echo $hash -> get ( 161803398 ), "\n" ;
echo $hash -> get ( 314159265 ), "\n" ;
?>
以上例程的输出类似于:
-- a lot bool(true) bool(false) -- a lot plus one
