Mysqli_fetch

The mysqli _ fetch _array() function fetches a result row as an associative array, a numeric array, or both. Scriptcase code generator. Note: Fieldnames returned from this function are case-sensitive.

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. I see many people are contributing in ways to help return result sets for prepared statements in ASSOSITAVE arrays the same as the mysqli _ fetch _assos function might return from a normal query issued via mysqli _query. PHP MySQLi Introduction.

The MySQLi functions allows you to access MySQL database servers. Differences in mysqli _ fetch functions. Ask Question Asked years, months ago. Active years, months ago.

Using mysqli_fetch _all() and an additional foreach() loop for post processing will be notably slower than using mysqli_fetch _array().
