PHP文件能成功执行，但是执行phpinfo()并未发现sqlsrv，执行数据库连接后提示如下：
PHP Fatal error: Call to undefined function sqlsrv_connect() in E:\wwwroot\php.com\test\2.php on line 11
----------------代码如下---------------
<?php
$serverName = "(local)";
$uid ="sa";
$pwd = "mypwd123";
$connectionInfo = array("UID"=>$uid,"PWD"=>$pwd,"Database"=>"phpdb");
$conn = sqlsrv_connect( $serverName,$connectionInfo);
if( $conn == false)
{
echo "连接失败！";
die( print_r( sqlsrv_errors(), true));
}
?>
