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
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 found and updated, 1 if the entry was newly added or 0 if there was an error.
例
例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 ) );
?>
上の例の出力は、 たとえば以下のようになります。
bool(false) int(2) int(16091) Set->Update int(1) int(29906)
