Parameters

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 .

Return Values

Returns an array of associative or numeric arrays holding result rows.

MySQL Native Driver Only

Available only with mysqlnd.

As mysqli_fetch_all returns all the rows as an array in a single step, it may consume more memory than some similar functions such as mysqli_fetch_array, which only returns one row at a time from the result set. Further, if you need to iterate over the result set, you will need a looping construct that will further impact performance. For these reasons mysqli_fetch_all should only be used in those situations where the fetched result set will be sent to another layer for processing.
