With the code mentioned above and in relation to a MSSQL query.

When using the following statements  to retrieve dat "fetch_assoc" then running a split statement PHP it then into a array it will not pass the data retrieved will show correctly in a XML document created by the DOM object.

<?php
require("phpsqlajax_dbinfo.php");

// Start XML file, create parent node

$dom = new DOMDocument("1.0");
$node = $dom->createElement("markers");
$parnode = $dom->appendChild($node);

// Opens a connection to a DreameyeOne server
$connection=mssql_connect ("ELF\ELF", $username, $password);
if (!
$connection) {
  die(
'Not connected : ' . mssql_error());
}

// Set the active DreameyOne database
$db_selected = mssql_select_db($database, $connection);
if (!
$db_selected) {
  die (
'Can\'t use db : ' . mssql_error());
}

// Select all the rows in the markers table
$query = "SELECT msg FROM ozekimessagein ORDER BY senttime DESC";
$result = mssql_query($query);
if (!
$result) {
  die(
'Invalid query: ' . mssql_error());
}
header("Content-type: text/xml");
// Iterate through the rows, adding XML nodes for each
while ($row = @mssql_fetch_assoc($result)) {
      list (
$vehicleID,$long,$lat) = split(',',$row);
// ADD TO XML DOCUMENT NODE
     
$node = $dom->createElement("marker");
     
$node = $dom->createElement("marker");
     
$newnode = $parnode->appendChild($node);
     
$newnode->setAttribute("VehicleID:",$vehicleID);
     
$newnode->setAttribute("lat",$lat);
     
$newnode->setAttribute("long",$long);
}

echo
$dom->saveXML();

?>

regarding 'The 30 character field name limit is still an issue'

Thought about using shorter column names and using the description to give more info regarding the column.

as to the
$result = mssql_query('SELECT articles.id, issues.id FROM articles, issues WHERE articles.pub_date = issues.pub_date');

try this
$result = mssql_query('SELECT articles.id as aid, issues.id as iid FROM articles, issues WHERE articles.pub_date = issues.pub_date');

Beware when using mssql_fetch_assoc() to return data pulled in from joined tables; if the tables have the same column names, the column mentioned last will overwrite the prior one when populating the assoc.

Example:

<?
$result
= mssql_query('SELECT articles.id, issues.id FROM articles, issues WHERE articles.pub_date = issues.pub_date');
$record = mssql_fetch_assoc($result);
print_r($record);

/*
Prints:

Array
(
    [id] => 123
)

*/
?>

We are running FreeTDS on a Linux Apache / PHP server and encountered the following error when calling mssql_fetch_assoc()

Fatal error: Call to undefined function mssql_fetch_assoc()

We were confused because *some* of the mssql commands worked, such as mssql_connect and mssql_fetch_array.  The trick to make mssql_fetch_assoc() work lies in configuring FreeTDS.  We had to change the statement to contain the --enable-msdblib switch:

./configure --enable-msdblib

We then recompiled PHP to include --with-mssql=/path/to/freetds and finally mssql_fetch_assoc() began working properly.

The 30 character field name limit is still an issue as of PHP 5.1.6, at least running under IIS.

WARNING: as of PHP 4.3.2

The keys in the array will only contain the 1st 30 characters of the column name if you have column names longer than that.
