QuickHashIntHash::set

(PECL quickhash >= Unknown)

QuickHashIntHash::set — This method updates an entry in the hash with a new value, or adds a new one if the entry doesn't exist

説明

public function QuickHashIntHash::set(int $key, int $value): int

This method tries to update an entry with a new value. In case the entry did not yet exist, it will instead add a new entry. It returns whether the entry was added or update. If there are duplicate keys, only the first found element will get an updated value. Use QuickHashIntHash::CHECK_FOR_DUPES during hash creation to prevent duplicate keys from being part of the hash.

パラメータ

key: The key of the entry to add or update.
value: The new value to set the entry with.

戻り値

2 if the entry was newly added, 1 if the entry was found and updated, or 0 if there was an error.

var_dump($hash->set(46692, 16091));
var_dump($hash->get(46692));

echo "\n\nSet->Update\n";
var_dump($hash->set(46692, 29906));
var_dump($hash->get(46692));

bool(false)
int(2)
int(16091)
