PHP calls MS SQL stored procedure

Calling MS SQL stored procedures in PHP

functiongenerateDocCode(){
$wf_id=self::WORKFLOW_ID;
$doc_code="";
$link=mssql_connect($this->cfg->db->params->host,$this->cfg->db->params->username,$this->cfg->db->params->password)ordie("Can'tconnectsqlserver");
mssql_select_db($this->cfg->db->params->dbname,$link)ordie("Selectdatabasefailure");
$stmt=mssql_init("GenerateDocCode",$link)ordie("initializestoredprocedurefailure");
mssql_bind($stmt,"@wf_id",$wf_id,SQLINT4);
mssql_bind($stmt,"@doc_code",$doc_code,SQLVARCHAR,true);
mssql_execute($stmt,false);
//print"DocCodeis:".$doc_code;
return$doc_code;
}

First call the mssql_init statement to initialize the stored procedure, then call the mssql_bind statement to specify the stored procedure parameters, and finally call mssql_execute to execute the stored procedure.
