(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
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.
keyThe key of the entry to add or update.
valueThe new value to set the entry with.
2 if the entry was found and updated, 1 if the entry was newly added or 0 if there was an error.
示例 #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 ) );
?>以上示例的输出类似于：
bool(false) int(2) int(16091) Set->Update int(1) int(29906)
