Question

I’m trying to set variables $upkeep_1, $upkeep_2, etc using a loop.
I have this code:

$sql_result2 = mysql_query("SELECT * FROM houses_db", $db); 
while ($rs2 = mysql_fetch_array($sql_result2)) {
   $upkeep_{$rs2[type]} = (int) $rs2[upkeep]; 
   }

echo $upkeep_3 . "<br>";

$rs2[type] is a number field, starting at one and going up to 8.

This code outputs nothing though, despite $rs[upkeep] being 3000. What am I doing wrong?

Answer 1

Why not using an array?

$sql_result2 = mysql_query("SELECT * FROM houses_db", $db); 
while ($rs2 = mysql_fetch_array($sql_result2)) {
    $upkeep[$rs2['type']] = (int) $rs2['upkeep']; 
}

echo $upkeep[3] . "<br>";
