$key
[, int $value

value
The optional value of the entry to add. If no value is specified, 1 will be used.
TRUE
when the entry was added, and FALSE
if the entry was not added.
Example #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 ) );
?>
以上例程的输出类似于:
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)
