QuickHashIntHash::set()
(PECL quickhash >= Unknown)
This method updates an entry in the hash with a new value, or adds a new one if the entry doesn't exist
说明
public QuickHashIntHash::set(int $key,int $value): bool
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.
参数
- $key
The key of the entry to add or update.
- $value
The new value to set the entry with.
返回值
2 if the entry was found and updated, 1 if the entry was newly added or 0 if there was an error.
范例
Example #1 QuickHashIntHash::set() example
<?php $hash = new QuickHashIntHash( 1024 ); echo "Set->Add\n"; var_dump( $hash->get( 46692 ) ); var_dump( $hash->set( 46692, 16091 ) ); var_dump( $hash->get( 46692 ) ); echo "Set->Update\n"; var_dump( $hash->set( 46692, 29906 ) ); var_dump( $hash->get( 46692 ) ); ?>
以上例程的输出类似于:
bool(false) int(2) int(16091) Set->Update int(1) int(29906)
