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));
}
