    QuickHashIntStringHash::update — This method updates an entry in the hash with a new value

    说明

    public QuickHashIntStringHash::update(int $key, string $value): bool

    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.

    参数

    key

    The key of the entry to update.

    value

    The new value for the entry. If a non-string is passed, it will be converted to a string automatically if possible.

    返回值

    true when the entry was found and updated, and false if the entry was not part of the hash already.

    示例

    示例 #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( 314159265, "a lot plus one" ) );
    var_dump( $hash->update( 314159999, "a lot plus one" ) );

    echo     $hash->get( 161803398 ), "\n";
    echo     $hash->get( 314159265 ), "\n";
    ?>

    以上示例的输出类似于：

    --
a lot
bool(true)
bool(false)
--
a lot plus one
