Question

while($fetchres = mysql_fetch_array($searchquery)) { 
        $v1 = $fetchres['v1']; $v2 = $fetchres['v2']; $v3 = $fetchres['v3']; 
        $v4 = $fetchres['v4']; $v5 = $fetchres['v5'];
        $v6 = $fetchres['v6']; 
        $v7 = $fetchres['v7'];
        }

Hi! How can I set this columns automatically? I mean my system automatically adds a column. For example my system adds a new column ‘v8’. But in my code, I only inputted until v7. How can I automatically code this fetching of query by depending on how many columns my system automatically made? Thanks.

Use extract.

while ($row = mysql_fetch_assoc($searchQuery))
{
  // Extract the keys of the array into the local symbol table.
  extract($row);

  // Now, all variables exist and you can echo them like this:
  echo $v1;
  echo $v8;
}

You still need to know the names of the variables. If you just want to echo everything inside, use foreach with a key assingnment:

while ($row = mysql_fetch_assoc($searchQuery))
{
  foreach($row as $key => $value) 
  {
    echo "$key: $value\n"; // Will output something like 'v1: foo' and 'v2: bar', separated by newlines.
  }
}
