  • QuickHashIntHash::set()

    (PECL quickhash >= Unknown)

    This method updates an entry in the hash with a new value, or adds a new one if the entry doesn't exist

    说明

    publicQuickHashIntHash::set(int $key,int $value): bool

    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.

    参数

    $key

    The key of the entry to add or update.

    $value

    The new value to set the entry with.

    返回值

    2 if the entry was found and updated, 1 if the entry was newly added or 0 if there was an error.

    范例

    Example #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 ) );
    ?>
    

    以上例程的输出类似于:

    bool(false)
    int(2)
    int(16091)
    Set->Update
    int(1)
    int(29906)
