Example #1 QuickHashIntStringHash::add() example
<?php
echo "without dupe checking\n" ;
$hash = new QuickHashIntStringHash ( 1024 );
var_dump ( $hash -> exists ( 4 ) );
var_dump ( $hash -> get ( 4 ) );
var_dump ( $hash -> add ( 4 , "twenty two" ) );
var_dump ( $hash -> exists ( 4 ) );
var_dump ( $hash -> get ( 4 ) );
var_dump ( $hash -> add ( 4 , "twelve" ) );
echo "\nwith dupe checking\n" ;
$hash = new QuickHashIntStringHash ( 1024 , QuickHashIntStringHash :: CHECK_FOR_DUPES );
var_dump ( $hash -> exists ( 4 ) );
var_dump ( $hash -> get ( 4 ) );
var_dump ( $hash -> add ( 4 , "seventy eight" ) );
var_dump ( $hash -> exists ( 4 ) );
var_dump ( $hash -> get ( 4 ) );
var_dump ( $hash -> add ( 4 , "nine" ) );
?>
以上例程的输出类似于:
without dupe checking bool(false) bool(false) bool(true) bool(true) string(10) "twenty two" bool(true)with dupe checking bool(false) bool(false) bool(true) bool(true) string(13) "seventy eight" bool(false)
