deyim
Sadece yordamsal tarz: mysqli_stmt_init() işlevinden dönen bir mysqli_stmt nesnesi.
An integer greater than zero indicates the number of rows affected or
retrieved. Zero indicates that no records were updated for an
UPDATE
statement, no rows matched the
WHERE
clause in the query or that no query has yet been
executed. -1
indicates that the query returned an error or
that, for a SELECT
query,
mysqli_stmt_affected_rows() was called prior to calling
mysqli_stmt_store_result().
Bilginize:
If the number of affected rows is greater than maximum PHP int value, the number of affected rows will be returned as a string value.
