In order to bind DATETIME, i suggest to convert the date to double, then use SQLFLT8 instead of SQLVARCHAR.
In SQL Server Datetime is a standard double. The integer part represent the number of days since 1-1-1900 and the fractional part represent the fraction of the day (e.g: 0.5 means noon, 0.75 means 6 PM).
Using SQLVARCHAR may lead to errors depending on the local server config.
<?php
function PhpTimeToOLEDateTime($timestamp)
{
$a_date = getdate ($timestamp);
$year= $a_date['year']; //this year
$partial_days = ($year-1900)*365;//days elapsed since 1-1-1900
//let's calculate how many 29 february from 1900 to first day on this year
$partial_days +=(int)(($year-1) / 4); //each 4 years a leap year since year 0
$partial_days -= (int)(($year-1) / 100); //each 100 years skip a leap
$partial_days += (int)(($year-1) / 400); //each 400 years add a leap
$partial_days -= 460; //459 leap years before 1900 + 1 for math (year 0 does not exist)
$partial_days += $a_date['yday'];
$seconds = $a_date['hours'] * 3600;
$seconds += $a_date['minutes'] * 60;
$seconds += $a_date['seconds'];
$d = (double) $partial_days;
$d += ((double)$seconds)/86400.0;
return $d;
}
?>
Sample binding
<?php
$now = PhpTimeToOLEDateTime(time());
mssql_bind($proc, "@dateparam", $now, SQLFLT8, false);
?>

if you are experiencing difficulties binding an empty string because it is being converted to NULL by your driver try the following:
<?php
if($var === ''){
//stupid hack to prevent mssql driver from converting empty strings to null. now they arent empty strings but they will get trimmed down to legth 0 ;-)
$var = ' ';
$type = SQLVARCHAR;
$isNull = false;
$maxLen = 0;
}
mssql_bind($stmt, $param_name, $var, $type, $is_output,$isNull, $maxLen);
?>

There isn't a bind function for regular SQL queries; not even a escape function. I found this nice piece of code:
<?php
function mssql_escape($data) {
if(is_numeric($data))
return $data;
$unpacked = unpack('H*hex', $data);
return '0x' . $unpacked['hex'];
}
?>

I found SQLVARCHAR better for datetime.
It was performing some other non-strtotime() convertions when it was set to SQLINT4

Use:
SQLVARCHAR for binary
SQLINT4 for datetime
SQLFLT8 for decimal
SQLVARCHAR for image
SQLFLT8 for money
SQLCHAR for nchar
SQLTEXT for ntext
SQLFLT8 for numeric
SQLVARCHAR for nvarchar
SQLFLT8 for real
SQLINT4 for smalldatetime
SQLFLT8 for smallmoney
SQLVARCHAR for sql_variant
SQLINT4 for timestamp
SQLVARCHAR for varbinary

I had the same problem but the posted solution above just produced null results. Here's a modification that ended up working:
#THIS SUCCEEDS, USES A REFERENCE
mssql_bind($proc, '@'.$key, $sp_parms[$key], SQLVARCHAR)
or die("Unable to bind $sp_name:$key<br>".mssql_get_last_message());

mssql_bind binds by reference, not by value, even on input parameters. Improper binding can cause strange errors; in my case "Error converting data type varchar to int"
--SAMPLE STORED PROCEDURE
CREATE Procedure [dbo].[myproc]
(
@one VARCHAR(10) = 'n1',
@two VARCHAR(10) = 'n2',
@three VARCHAR(10) = 'n3',
@four VARCHAR(10) = 'n4',
@five VARCHAR(10) = 'n5'
)
AS
BEGIN
SET NOCOUNT ON;
SELECT
@one AS 'one',
@two AS 'two',
@three AS 'three',
@four AS 'four',
@five AS 'five'
END
//SAMPLE PHP CALL
$sp_name = 'mydb.dbo.myproc';
$proc = mssql_init($sp_name);
$sp_parms->one = 'one';
$sp_parms->two = 'two';
$sp_parms->three = 'three';
foreach ($sp_parms as $key=>$parm) {
#THIS FAILS, because it's binding values!
#mssql_bind($proc, '@'.$key, $parm, SQLVARCHAR)
# or die("Unable to bind $sp_name:$key<br>".mssql_get_last_message());
#THIS SUCCEEDS, USES A REFERENCE
mssql_bind($proc, '@'.$key, $sp_parms->$key, SQLVARCHAR)
or die("Unable to bind $sp_name:$key<br>".mssql_get_last_message());
}
