look-up table help

You did not specify which database you are working with. This is important, but I will assume mysql.

Here is a code example that will show you how to connect to mysql, how to select a specific database, execute a query, then work with the returned recordset.

<?php

$server = "localhost"; // Name or IP of database server.
$user   = ""; // username
$pwd    = ""; // password
$db     = ""; // Name of database to connect to.

if (!$cnn = mysql_connect($server,$user,$pwd )) {
  die("mysql_connect() failed");
}

if (!mysql_select_db($db,$cnn)) {
  die("Could not select database named ".$db);
}

$sql = "select * from pairHistoryLookup where pairID = 15";

/* Execute the query. */
if (!$res = @mysql_query($sql)) {
  die(mysql_error());
  return false;
}
/* Create an array of arrays out of the recordset. */
while ($row = mysql_fetch_array($res, MYSQL_ASSOC)) {
  $data[] = $row;
}

/* Now iterate through the recordset creating a simple table. */
echo "<style>table.dump { font-family:Arial; font-size:8pt; }</style>";
echo "<table class=\"dump\" border=\"1\" cellpadding=\"1\" cellspacing=\"0\">\n";
echo "<tr>";
echo "<th>#</th>";
foreach($data[0] as $key=>$val) {
  echo "<th><b>";
  echo $key;
  echo "</b></th>";
}
echo "</tr>\n";
$row_cnt = 0;
foreach($data as $row) {
  $row_cnt++;
  echo "<tr align='center'>";
  echo "<td>".$row_cnt."</td>";
  foreach($row as $val) {
    echo "<td>";
    echo $val;
    echo "</td>";
  }
  echo"</tr>\n";
}
echo "</table>\n";    

?>
