Question

Lets say I have a MySQL table, Users, like this –

-----------------------------------------
ID      | FirstName    | LastName
-----------------------------------------
1       | ABC          | XYZ
2       | DEF          | LMN
3       | GHI          | PQR
-----------------------------------------

And I can fetch results using simple MySQL query like

SELECT ID, FirstName, LastName FROM Users

Now what I am looking for is to store the query results in an associative array form. The structure would be something like this –

Array
(
[ID] => Array
(
[0] => FirstName
[1] => LastName
)
)

SO the above query result should get stored in an array like this –

Array
(
  [1] => Array
  (
  [0] => ABC
  [1] => XYZ
  )
  [2] => Array
  (
  [0] => DEF
  [1] => LMN
  )
  [3] => Array
  (
  [0] => GHI
  [1] => PQR
  )
)

I know about array_push. But I wonder if that needs to be used. How can get this result ?

Answer 1

$result = mysql_query('SELECT ID, FirstName, LastName FROM Users');

$data = array();
while ($row = mysql_fetch_assoc($result)) {
  $id = array_shift($row); // Shifts first element
  $data[$id] = $row; 
}

You can use inside while a shorter version $data[array_shift($row)] = $row;
