mssql_bind — Adds a parameter to a stored procedure or a remote stored procedure
$stmt
, string $param_name
, mixed &$var
, int $type
[, bool $is_output = false
[, bool $is_null = false
[, int $maxlen = -1
]]] )Binds a parameter to a stored procedure or a remote stored procedure.
stmt
Statement resource, obtained with mssql_init().
param_name
The parameter name, as a string.
Note:
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. It is passed 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
Whether 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
Whether 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.
Returns TRUE on success or FALSE on failure.

<?php
// Connect to MSSQL and select the database
mssql_connect('KALLESPC\SQLEXPRESS', 'sa', 'phpfi');
mssql_select_db('php');
// Create a new stored prodecure
$stmt = mssql_init('NewUserRecord');
// Bind the field names
mssql_bind($stmt, '@username', 'Kalle', SQLVARCHAR, false, false, 60);
mssql_bind($stmt, '@name', 'Kalle', SQLVARCHAR, false, false, 60);
mssql_bind($stmt, '@age', 19, SQLINT1, false, false, 3);
// Execute
mssql_execute($stmt);
// Free statement
mssql_free_statement($stmt);
