$key
, string $value

The key of the entry to add.
value
The new value for the entry. If a non-string is passed, it will be converted to a string automatically if possible.
TRUE
when the entry was found and updated, and FALSE
if the entry was
not part of the hash already.
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
