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.
stmtStatement resource, obtained with mssql_init().
param_nameThe 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().
varThe 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_outputWhether 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.
