Beschrijving

Fetch the entire result set of a query and return it into a nested array. The function takes care of doing the query and freeing the results when finished.

Parameter

string $query

the SQL query

array $types

if supplied, the types of the columns in the result set will be set for fetching

integer $fetchmode

the fetch mode to use

boolean $rekey

if set to TRUE the array result be modified as follows: If the result set contains more than two columns, the value will be an array of the values from column 2 to n. If the result set contains only two columns, the returned value will be a scalar with the value of the second column (unless forced to an array with the $force_array parameter).

boolean $force_array

used only if the query returns exactly two columns. If TRUE, the values of the returned array will be one-element arrays instead of scalars.

boolean boolean $group

if TRUE, the values of the returned array is wrapped in another array. If the same key value (in the first column) repeats itself, the values will be appended to this array instead of overwriting the existing values.
