There is a limitation of 30 characters for the field name. So if your query has  `fieldname AS really_long_overly_descriptive_name`, you will only get `really_long_overly_descriptiv` back

<?php
// Send a select query to MSSQL
$query = mssql_query('SELECT [username] AS [really_long_overly_descriptive_name], [name], [email] FROM [php].[dbo].[userlist]');

echo 'Result set contains the following field(s):', PHP_EOL;

// Dump all field names in result
for ($i = 0; $i < mssql_num_fields($query); ++$i) {
    echo ' - ' . mssql_field_name($query, $i), PHP_EOL;
}

// Free the query result
mssql_free_result($query);
?>

Outputs the following:

Result set contains the following field(s):
 - really_long_overly_descriptiv
 - name
 - email

A simple script to walk through an MSSQL server.
I'm using PHP 4.06 and Freetds 5.1 on Solaris 2.7 and Apache 1.3
Several of the msql_ functions seem to be broken/missing.
This is what I found to work.

<?php
// --------------------------------------------------------
// URL http://server/mssqltest.php?DB=Database&table=TableName
// --------------------------------------------------------
// Default settings: edit to meet your needs
if (!($user)) $user=sa;
if (!($pass)) $pass="password";
if (!($host)) $host="acer900";
// --------------------------------------------------
// connect to mssql server
$connect = mssql_connect($host,$user,$pass) or die ($host." not accessible.");
// select the database
if ($DB) mssql_select_db($DB)or die('USE '.$DB.' failed!');
if (!($table)) {
    $query="EXEC sp_tables \"%\",\"%\",\"".$DB."\",\"'TABLE'\"";
    $linkcol=2;
    $linkcol="TABLE_NAME";
$linkformat=" <a href=\"%s?DB=".$DB."&table=%s\">%s</a> ";
}else{ // tables and DB - Get DATA
    $query="SELECT * FROM ".$table;
    $linkformat=" <a href=\"%s\">%s</a> ";
}
if (!($DB))    {
    $query="EXEC sp_databases";
    $linkcol=0;
    $linkcol="DATABASE_NAME";
    $linkformat="<a href=\"%s?DB=%s\">%s</a>";
}

// run query
echo $query."<br>";
$result = mssql_query( $query) or die('Query failed!');
$fields = mssql_num_fields ($result) or die("Num Fields Failed");
$rows   = mssql_num_rows ($result);

echo "<br>Rows ".$rows." Fields ".$fields."<br>";
echo "<TABLE border=1><tr>";
// get field names
for ( $f = 0 ; $f < $fields ; $f++ ){
    $name = mssql_fetch_field($result, $f);
    echo "<td>".$f.$name->name."</td>";
// Strange here.. without the "X"'s the () is always TRUE??
    if ($name->name."X" == $linkcol."X") $linkcol = $f;
}
echo "</tr>";
//Display Data
for ($i = 0; $i < $rows ; $i =$i +1){
    for ($f = 0; $f<$fields ; $f++){
        $name=mssql_result($result,$i,$f);
        if ($f == $linkcol){
printf("<td>".$linkformat."</td>\n",$PHP_SELF,
 $name , $name );
        }
        else{
            echo "<td>". $name . "</td>";
        }
    }
echo "</tr>";
}
echo "</TABLE><br>";

// close connection
mssql_close ($connect);
?>

This function isn't supported (PHP 4.0.2) if using Sybase/FreeTDS to access SQLServer (linux/solaris/bsd/etc).  Instead, use "mssql_fetch_field()" like so:

$field_name = mssql_fetch_field($query_result, $field_number);
print $field_name->name;
