Retrieves an entire SQL result set from the database (i.e., many rows).

Description

Executes a SQL query and returns the entire SQL result.

Parameters

$querystringoptional

SQL query.

Default:null

$outputstringoptional

Any of ARRAY_A | ARRAY_N | OBJECT | OBJECT_K constants.
With one of the first three, return an array of rows indexed from 0 by SQL result row number. Each row is an associative array (column => value, …), a numerically indexed array (0 => value, …), or an object ( ->column = value ), respectively. With OBJECT_K, return an associative array of row objects keyed by the value of each row’s first column’s value. Duplicate keys are discarded.

Default:OBJECT

Return
