  • QuickHashIntStringHash::add()

    (PECL quickhash >= Unknown)

    This method adds a new entry to the hash

    说明

    publicQuickHashIntStringHash::add(int $key,string $value): bool

    This method adds a new entry to the hash, and returns whether the entry was added. Entries are by default always added unless QuickHashIntStringHash::CHECK_FOR_DUPES has been passed when the hash was created.

    参数

    $key

    The key of the entry to add.

    $value

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

    返回值

    TRUE when the entry was added, and FALSE if the entry was not added.

    范例

    Example #1 QuickHashIntStringHash::add() example

    <?php
    echo "without dupe checking\n";
    $hash = new QuickHashIntStringHash( 1024 );
    var_dump( $hash->exists( 4 ) );
    var_dump( $hash->get( 4 ) );
    var_dump( $hash->add( 4, "twenty two" ) );
    var_dump( $hash->exists( 4 ) );
    var_dump( $hash->get( 4 ) );
    var_dump( $hash->add( 4, "twelve" ) );
    echo "\nwith dupe checking\n";
    $hash = new QuickHashIntStringHash( 1024, QuickHashIntStringHash::CHECK_FOR_DUPES );
    var_dump( $hash->exists( 4 ) );
    var_dump( $hash->get( 4 ) );
    var_dump( $hash->add( 4, "seventy eight" ) );
    var_dump( $hash->exists( 4 ) );
    var_dump( $hash->get( 4 ) );
    var_dump( $hash->add( 4, "nine" ) );
    ?>
    

    以上例程的输出类似于:

    without dupe checking
    bool(false)
    bool(false)
    bool(true)
    bool(true)
    string(10) "twenty two"
    bool(true)
    with dupe checking
    bool(false)
    bool(false)
    bool(true)
    bool(true)
    string(13) "seventy eight"
    bool(false)
