mysqli_result::fetch_all -- mysqli_fetch_all — Fetches all result rows as an associative array, a numeric array, or both

### Description

Object oriented style

mixed mysqli_result::fetch_all ([ int `$resulttype` = MYSQLI_NUM ] )

Procedural style

mixed mysqli_fetch_all ( mysqli_result `$result` [, int `$resulttype` = MYSQLI_NUM ] )

mysqli_fetch_all() fetches all result rows and returns the result set as an associative array, a numeric array, or both.

### 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.
