QuickHashStringIntHash::add — This method adds a new entry to the hash
说明
public QuickHashStringIntHash::add
( string $key
, int $value
) : bool
This method adds a new entry to the hash, and returns whether the entry was added. Entries are by default always added unless QuickHashStringIntHash::CHECK_FOR_DUPES has been passed when the hash was created.
参数
key- The key of the entry to add.
value- The value of the entry to add.
返回值
true when the entry was added, and false if the entry was not added.
范例
Example #1 QuickHashStringIntHash::add() example
<?phpecho "without dupe checking\n";$hash = new QuickHashStringIntHash( 1024 );var_dump( $hash );var_dump( $hash->exists( "four" ) );var_dump( $hash->get( "four" ) );var_dump( $hash->add( "four", 22 ) );var_dump( $hash->exists( "four" ) );var_dump( $hash->get( "four" ) );var_dump( $hash->add( "four", 12 ) );echo "\nwith dupe checking\n";$hash = new QuickHashStringIntHash( 1024, QuickHashStringIntHash::CHECK_FOR_DUPES );var_dump( $hash );var_dump( $hash->exists( "four" ) );var_dump( $hash->get( "four" ) );var_dump( $hash->add( "four", 78 ) );var_dump( $hash->exists( "four" ) );var_dump( $hash->get( "four" ) );var_dump( $hash->add( "four", 9 ) );?>
以上例程的输出类似于：
without dupe checking
object(QuickHashStringIntHash)#1 (0) {
}
bool(false)
bool(false)
bool(true)
bool(true)
int(22)
bool(true)
with dupe checking
object(QuickHashStringIntHash)#2 (0) {
}
bool(false)
bool(false)
bool(true)
bool(true)
int(78)
bool(false)
