Fetch the entire result set of a query and return it as an associative array using the first column as the key. The function takes care of doing the query and freeing the results when finished. 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).
Parameter
string $query
the SQL query or the statement to prepare
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.
mixed $params
array, string or numeric data to be added to the prepared statement. Quantity of items passed must match quantity of placeholders in the prepared statement: meaning 1 placeholder for non-array parameters or 1 placeholder per array element.
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.
Return value
array - associative array with results from the query.
Check the SQL query or choose another get*() function
every other error code
Database specific error
Check the database related section of PHP-Manual to detect the reason for this error. In the most cases a misformed SQL statment. Ie. using LIMIT in a SQL-Statment for an Oracle database.
