php 扩展sqlsrv调用mssql存储过程

$serverName = "127.0.0.1";    $connectionInfo = array( "UID"=>"sa","PWD"=>"","Database"=>"test");    $conn = sqlsrv_connect( $serverName, $connectionInfo);    if( $conn === false )    {         echo "Could not connect.\\n";         die( print_r( sqlsrv_errors(), true));    }    $spnumber = '10655****00';    $chargenumber = '155****6789';    //参数需要以如下数组方式赋值并标明类型，SQLSRV_PARAM_IN是输入类型，SQLSRV_PARAM_OUT是输出类型。注意要按照存储过程定义的顺序赋值    $params = array(                      array(&$spnumber, SQLSRV_PARAM_IN),                     array(&$chargenumber, SQLSRV_PARAM_IN)                   );    $tsql_callSP = "{call msgexpress_UnicomNewSubmit(?,?)}";    $stmt3 = sqlsrv_query( $conn, $tsql_callSP, $params);    if( $stmt3 === false )    {         echo "Error in executing statement 3.\\n";         die( print_r( sqlsrv_errors(), true));    }
