mssql_bind
(PHP 4 >= 4.0.7, PHP 5, PECL odbtp:1.1.1-1.1.4)
mssql_bind — Adds a parameter to a stored procedure or a remote stored procedure
Popis
bool mssql_bind ( resource $stmt, string $param_name, mixed &$var, int $type [, int $is_output [, int $is_null [, int $maxlen]]] )Binds a parameter to a stored procedure or a remote stored procedure.
Seznam parametrů
- stmt
Statement resource, obtained with mssql_init().
- param_name
The parameter name, as a string.
Poznámka: You have to include the @ character, like in the T-SQL syntax. See the explanation included in mssql_execute().
- var
The PHP variable you'll bind the MSSQL parameter to. You can pass it by value, or by reference, to retrieve OUTPUT and RETVAL values after the procedure execution.
- type
One of: SQLTEXT, SQLVARCHAR, SQLCHAR, SQLINT1, SQLINT2, SQLINT4, SQLBIT, SQLFLT4, SQLFLT8, SQLFLTN.
- is_output
Wether the value is an OUTPUT parameter or not. If it's an OUTPUT parameter and you don't mention it, it will be treated as a normal input parameter and no error will be thrown.
- is_null
Wether the parameter is NULL or not. Passing the NULL value as var will not do the job.
- maxlen
Used with char/varchar values. You have to indicate the length of the data so if the parameter is a varchar(50), the type must be SQLVARCHAR and this value 50.

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());
}
