Description
public QuickHashIntHash::add(int
$key, int $value = ?): bool
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.
Parameters
-
key -
The key of the entry to add.
-
value -
The optional value of the entry to add. If no value is specified,
1will be used.
Return Values
true when the entry was added, and false if the entry was not added.
Examples
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 ) );
?>
The above example will output something similar to:
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)
