mysqli_fetch_array
(PHP 5)
mysqli_fetch_array(no version information, might be only in CVS)
result->fetch_array() -- Fetch a result row as an associative, a numeric array, or bothPopis
Procedural style:
mixed mysqli_fetch_array ( mysqli_result result [, int resulttype] )Object oriented style (method):
class mysqli_result {mixed fetch_array ( [int resulttype] )
}
Returns an array that corresponds to the fetched row or NULL if there
are no more rows for the resultset represented by the
result
parameter.
mysqli_fetch_array() is an extended version of the mysqli_fetch_row() function. In addition to storing the data in the numeric indices of the result array, the mysqli_fetch_array() function can also store the data in associative indices, using the field names of the result set as keys.
Poznámka: Názvy polà vrácené touto funkcà rozliÅ¡ujà velikost pÃsmen.
Poznámka: Tato funkce nastavuje pole s hodnotou NULL na hodnotu PHP NULL.
If two or more columns of the result have the same field names, the last column will take precedence and overwrite the earlier data. In order to access multiple columns with the same name, the numerically indexed version of the row must be used.
Seznam parametrů
result
Procedural style only: A result set identifier returned by mysqli_query(), mysqli_store_result() or mysqli_use_result().
resulttype
This optional parameter is a constant indicating what type of array should be produced from the current row data. The possible values for this parameter are the constants MYSQLI_ASSOC, MYSQLI_NUM, or MYSQLI_BOTH. Defaults to MYSQLI_BOTH.
By using the MYSQLI_ASSOC constant this function will behave identically to the mysqli_fetch_assoc(), while MYSQLI_NUM will behave identically to the mysqli_fetch_row() function. The final option MYSQLI_BOTH will create a single array with the attributes of both.
Návratové hodnoty
Returns an array that corresponds to the fetched row or NULL if there are no more rows in resultset.
