msql_fetch_array

(PHP 4, PHP 5)

msql_fetch_arrayFetch row as array

Descrizione

array msql_fetch_array ( resource $result [, int $result_type ] )

msql_fetch_array() is an extended version of msql_fetch_row(). In addition to storing the data in the numeric indices of the result array, it also stores the data in associative indices, using the field names as keys.

An important thing to note is that using msql_fetch_array() is NOT significantly slower than using msql_fetch_row(), while it provides a significant added value.

A constant that can take the following values: MSQL_ASSOC, MSQL_NUM, and MSQL_BOTH with MSQL_BOTH being the default.
