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";
