范例
Example #1 QuickHashStringIntHash::add() example
<?php
echo "without dupe checking\n";
$hash = new QuickHashStringIntHash( 1024 );
var_dump( $hash );
var_dump( $hash->exists( "four" ) );
var_dump( $hash->get( "four" ) );
var_dump( $hash->add( "four", 22 ) );
var_dump( $hash->exists( "four" ) );
var_dump( $hash->get( "four" ) );
var_dump( $hash->add( "four", 12 ) );
echo "\nwith dupe checking\n";
$hash = new QuickHashStringIntHash( 1024, QuickHashStringIntHash::CHECK_FOR_DUPES );
var_dump( $hash );
var_dump( $hash->exists( "four" ) );
var_dump( $hash->get( "four" ) );
var_dump( $hash->add( "four", 78 ) );
var_dump( $hash->exists( "four" ) );
var_dump( $hash->get( "four" ) );
var_dump( $hash->add( "four", 9 ) );
?>
以上例程的输出类似于:
without dupe checking object(QuickHashStringIntHash)#1 (0) { } bool(false) bool(false) bool(true) bool(true) int(22) bool(true) with dupe checking object(QuickHashStringIntHash)#2 (0) { } bool(false) bool(false) bool(true) bool(true) int(78) bool(false)
