(PECL quickhash >= Unknown)
QuickHashIntStringHash::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 QuickHashIntStringHash::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 value of the entry to add. If a non-string is passed, it will be converted to a string automatically if possible.
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 QuickHashIntStringHash::set() example
<?php
$hash = new QuickHashIntStringHash( 1024 );
echo "Set->Add\n";
var_dump( $hash->get( 46692 ) );
var_dump( $hash->set( 46692, "sixteen thousand ninety one" ) );
var_dump( $hash->get( 46692 ) );
echo "Set->Update\n";
var_dump( $hash->set( 46692, "twenty nine thousand nine hundred six" ) );
var_dump( $hash->get( 46692 ) );
?>以上示例的输出类似于：
Set->Add bool(false) int(2) string(27) "sixteen thousand ninety one" Set->Update int(1) string(37) "twenty nine thousand nine hundred six"
