QuickHashIntHash::add()

(PECL quickhash >= Unknown)

This method adds a new entry to the hash

说明

publicQuickHashIntHash::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.

参数

$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.

返回值

TRUE when the entry was added, and FALSE if the entry was not added.

范例

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)
