(PHP 5, PHP 7, PHP 8)

Einführung

Stellt das Ergebnis einer Datenbankabfrage dar.

class mysqli_result implements IteratorAggregate {

/* Eigenschaften */

public readonly int $current_field;

public readonly int $field_count;

public readonly ?array $lengths;

public readonly int|string $num_rows;

public int $type;

/* Methoden */

public __construct(mysqli $mysql, int $result_mode = MYSQLI_STORE_RESULT)

public data_seek(int $offset): bool

public fetch_all(int $mode = MYSQLI_NUM): array

public fetch_array(int $mode = MYSQLI_BOTH): array|null|false

public fetch_assoc(): array|null|false

public fetch_column(int $column = 0): null|int|float|string|false

public fetch_field_direct(int $index): object|false

public fetch_field(): object|false

public fetch_fields(): array

public fetch_object(string $class = "stdClass", array $constructor_args = []): object|null|false

public fetch_row(): array|null|false

public field_seek(int $index): bool

public free(): void

public close(): void

public free_result(): void

}

type: Legt als Integer fest, ob das Ergebnis gepuffert werden soll (MYSQLI_STORE_RESULT) oder nicht (MYSQLI_USE_RESULT).

Version	Beschreibung
8.0.0	mysqli_result implementiert nun IteratorAggregate. Zuvor wurde stattdessen Traversable implementiert.

mysqli_result::__construct — Constructs a mysqli_result object

mysqli_result::data_seek — Adjusts the result pointer to an arbitrary row in the result
mysqli_result::fetch_all — Fetch all result rows as an associative array, a numeric array, or both
mysqli_result::fetch_array — Fetch the next row of a result set as an associative, a numeric array, or both
mysqli_result::fetch_assoc — Fetch the next row of a result set as an associative array
mysqli_result::fetch_column — Fetch a single column from the next row of a result set
mysqli_result::fetch_field_direct — Fetch meta-data for a single field
mysqli_result::fetch_field — Returns the next field in the result set
mysqli_result::fetch_fields — Returns an array of objects representing the fields in a result set
mysqli_result::fetch_object — Fetch the next row of a result set as an object
mysqli_result::fetch_row — Fetch the next row of a result set as an enumerated array
mysqli_result::$field_count — Gets the number of fields in the result set
mysqli_result::field_seek — Set result pointer to a specified field offset
mysqli_result::free — Frees the memory associated with a result
mysqli_result::getIterator — Retrieve an external iterator
mysqli_result::$lengths — Returns the lengths of the columns of the current row in the result set
mysqli_result::$num_rows — Gets the number of rows in the result set
