i need the sql query that would make an associative array from this table and give me values like this
id=>age
1=>10
4=>56
i also need to make all the id's as a variable where there value would be the age like
$1 = 10
$4 = 56
or if i could add a prefix to the variables
$id_1 = 10
$id_4 = 56
thanks in advance

Answer 1

In PHP, mysql_fetch_assoc() takes the result of a query, and returns one row as an associative array. Call it repeatedly to get all rows.

Answer 2

if your using php for fetching your data you may use the function mysql_fetch_array example:
while($row = mysql_fetch_assoc($resource))
{
echo $row['name'].'<br>';
}
you may know more about mysql functions for php on this site: http://www.php.net/manual/en/book.mysql.php

Answer 3

$ids = '1, 4';
$sql = "select age from __TABLE__ where id in ( {$ids} )";
$link = mysql_connect('__SERVER__', '__DBUSER__', '__DB_PWD__') or die('connect error');
$db = mysql_select_db('__DBNAME__', $link) or die('db error');
$rs = mysql_query($sql, $link);
$result = array();
while($row = mysql_fetch_assoc($rs))
{
$result[] = $row;
}
extract(my_result($result));
var_dump($id_1);
var_dump($id_4);
function my_result($result, $prefix = 'id_')
{
$data = array();
foreach($result as $k => $v)
{
$data[$prefix . $v['id']] = $v['order_no'];
}
return $data;
}
