Beispiel #1 QuickHashIntHash::add() example
<?php
echo "without dupe checking\n";
$hash = new QuickHashIntHash( 1024 );
var_dump( $hash->exists( 4 ) );
var_dump( $hash->get( 4 ) );
var_dump( $hash->add( 4, 22 ) );
var_dump( $hash->exists( 4 ) );
var_dump( $hash->get( 4 ) );
var_dump( $hash->add( 4, 12 ) );
echo "\nwith dupe checking\n";
$hash = new QuickHashIntHash( 1024, QuickHashIntHash::CHECK_FOR_DUPES );
var_dump( $hash->exists( 4 ) );
var_dump( $hash->get( 4 ) );
var_dump( $hash->add( 4, 78 ) );
var_dump( $hash->exists( 4 ) );
var_dump( $hash->get( 4 ) );
var_dump( $hash->add( 4, 9 ) );
echo "\ndefault value\n";
var_dump( $hash->add( 5 ) );
var_dump( $hash->get( 5 ) );
?>
Das oben gezeigte Beispiel erzeugt eine ähnliche Ausgabe wie:
without dupe checking bool(false) bool(false) bool(true) bool(true) int(22) bool(true) with dupe checking bool(false) bool(false) bool(true) bool(true) int(78) bool(false) default value bool(true) int(1)
