ORDER BY table2.number_reg

You could always use AS

$query = mysql_query(SELECT tbl.column AS 'tbl.column' FROM tbl AS tbl ... );

then iterate the values and sort

foreach(mysql_fetch_assoc($query) as $col=>$val){
   list($tbl,$col) = explode('.',$col);
}

or use the mysql_field_table() and mysql_field_name() functions

$query = mysql_query(...);
$fieldCt = mysql_num_fields($query);
for($i = 0; $i < mysql_num_fields($query); $i++){
    $field[$i] = mysql_field_table($query,$i).'.'.mysql_field_name($query,$i);
}
for($i = 0; $i < mysql_num_rows($query); $i++){
 foreach($field as $key=>$name){
   $row[$i][$name] = mysql_result($query,$i,$key);
 }
}

I didn't test it or anything, but that should map a query like that to an array $row with each entry being an array consisting of tbl_name.field_name => value entries.
