QuickHashIntStringHash::update — This method updates an entry in the hash with a new value
This method updates an entry with a new value, and returns whether the entry was 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 update.
valueThe new value for the entry. If a non-string is passed, it will be converted to a string automatically if possible.
true when the entry was found and updated, and false if the entry was
not part of the hash already.
例1 QuickHashIntStringHash::update() example
<?php
$hash->add( 161803398, "--" );
$hash->add( 314159265, "a lot" );
echo $hash->get( 161803398 ), "\n";
echo $hash->get( 314159265 ), "\n";

var_dump( $hash->update( 314159999, "a lot plus one" ) );
echo $hash->get( 161803398 ), "\n";
