mssql_fetch_batch
If you want to describe table like DESCRIBE in MySQL you can use this:
$sql = <<<SQL
SELECT column_name,data_type,column_default,is_nullable
FROM
information_schema.tables AS t
JOIN
information_schema.columns AS c ON
t.table_catalog=c.table_catalog AND
t.table_schema=c.table_schema AND
t.table_name=c.table_name
WHERE
t.table_name='TABLE-NAME'
SQL;
mssql_fetch_field
(PHP 4, PHP 5, PECL odbtp:1.1.1-1.1.4)
mssql_fetch_field — Get field information
Description
object mssql_fetch_field
( resource $result
[, int $field_offset
] )
mssql_fetch_field() can be used in order to obtain information about fields in a certain query result.
Parameters
- result
-
The result resource that is being evaluated. This result comes from a call to mssql_query().
- field_offset
-
The numerical field offset. If the field offset is not specified, the next field that was not yet retrieved by this function is retrieved. The field_offset starts at 0.
Return Values
Returns an object containing field information.
The properties of the object are:
- name - column name. if the column is a result of a function, this property is set to computed#N, where #N is a serial number.
- column_source - the table from which the column was taken
- max_length - maximum length of the column
- numeric - 1 if the column is numeric
- type - the column type.

For really detailed table information, use syscolumns, like this:
SELECT c.name, c.prec, c.scale, t.name type
FROM syscolumns c, systypes t, sysobjects o
WHERE o.name = 'yourtablename' AND o.id = c.id AND c.xtype = t.xtype
For other properties see the MS SQL online help. Search for 'syscolumns'.
Or an another solution:
sp_columns @table_name = 'yourtablename', @column_name = 'thecolumnname'
//no "select ..." !!!!
This gives info about only the specified column.

commenting Reynard Hilman:
for me it looks like the colstat field value of 1 in syscolumns table indicates an Identity Column.

If you want to describe table structure (like mysql 'desc table' command), sending this query might help:
<?
$sql = "SELECT c.name, c.isnullable, c.length, c.colstat, t.name type
FROM syscolumns c, systypes t, sysobjects o
WHERE o.name = '$table' AND o.id = c.id AND c.xtype = t.xtype";
?>
I suspect the colstat field in syscolumns table indicates primary key when its value is 1

Be aware that this function will only return the first 30 characters of the name of the column. If the actual column name is longer, it will be truncated. This is at least true with the following setup:
PHP 4.3.1
MSSQL 8.00.760
Have a good day everyone!

As kubalaa at bigfoot dot com note mssql_fetch_field->column_source return field name instead table name also with MSSQL2000 connection. Be adwised!!!

When you mssql_fetch_field(int result), you need to do loop to get the name of each field. Something like:
while($fld = mssql_fetch_field($rs)){
echo $fld->name . "<br>";
}
I am wondering why we cannot refer it by a field number.

It seems fairly hard to get a list of the tables from your database using MSSQL but this seems to do the trick. This is set to get only the User Tables and ignores the sytem tables.
<?php
mssql_connect("server","","") or die ("help me!");
mssql_select_db("") or die ("Noooo!");
$result = mssql_query ("sp_tables");
$fields = mssql_num_fields ($result);
$rows = mssql_num_rows ($result);
for ($f=0; $f<$rows; $f++) {
$CHKTYPE=GetField($result,"TABLE_TYPE",$f);
if($CHKTYPE=='TABLE'){
//$name = mssql_fetch_field($result, 2);
$field=GetField($result,"TABLE_NAME",$f)."<br>";
echo $field;
}
}
?>

Using this function with MSSQL 7, $returned->column_source is the column name, not the table name as it should be.
