QuickHashIntHash::add — This method adds a new entry to the hash
$key
[, int $value
] )This method adds a new entry to the hash, and returns whether the entry was added. Entries are by default always added unless QuickHashIntHash::CHECK_FOR_DUPES has been passed when the hash was created.
key
The key of the entry to add.
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)
