$key
, int $value
)This method updates an entry with a new value, and returns whether the entry was update. If there are duplicate keys, only the first found element will get an updated value. Use QuickHashStringIntHash::CHECK_FOR_DUPES during hash creation to prevent duplicate keys from being part of the hash.
key

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 QuickHashStringIntHash::update() example
<?php
$hash = new QuickHashStringIntHash ( 1024 );
$hash -> add ( 'six' , 314159265 );
$hash -> add ( "a lot" , 314159265 );
echo $hash -> get ( 'six' ), "\n" ;
echo $hash -> get ( 'a lot' ), "\n" ;
var_dump ( $hash -> update ( 'a lot' , 314159266 ) );
var_dump ( $hash -> update ( "a lot plus one" , 314159999 ) );
echo $hash -> get ( 'six' ), "\n" ;
echo $hash -> get ( 'a lot' ), "\n" ;
?>
以上例程的输出类似于:
314159265 314159265 bool(true) bool(false) 314159265 314159266
