奇怪的PHP换行问题-尝试使用换行将字符串转换为数组，大多数情况下都有效，但在特定的服务器上无效 - Odd PHP newline issue - trying to convert string to array using new line, works most of the time but not on one particular server

Odd PHP newline issue - trying to convert string to array using new line, works most of the time but not on one particular server

我有一个完美的工作函数

    function response( $array ) {
        $response = array();
        $results  = preg_split( '/$'R?^/m', $array );
        foreach( $results as $result ){ 
            $value = explode( '=', $result, 2 );
            $response[trim($value[0])] = trim($value[1]);
        }
        return $response;
    }

但是，在一个特定的网站上，使用PHP 5.3.3，它无法正常工作。

在我尝试过的其他所有网站上，我都有

    Array
    (
[VPSProtocol] => 3.00
[Status] => 3DAUTH
[StatusDetail] => 2007 : Please redirect your customer to the ACSURL, passing the MD and PaReq.

    )

但在5.3.3服务器上，我得到了

    )

感谢收到任何建议或想法-我没有访问服务器修改PHP的权限，但我有足够的权限访问PHP信息等。

编辑

我开始使用的字符串总是显示工作换行符，例如

    VPSProtocol=3.00
    Status=3DAUTH
    StatusDetail=2007 : Please redirect your customer to the ACSURL, passing the MD and PaReq.
    3DSecureStatus=OK
    MD=2014590211813198670

我使用的开发人员文档说

编码方式为"名称=值"字段，由回车换行符（CRLF）分隔。

在这种情况下，工作正常

function response( $array ) {
    $response = array();
    $results  = preg_split( '#'n(?!s)#', $array );
    foreach( $results as $result ){ 
        $value = explode( '=', $result, 2 );
        $response[trim($value[0])] = trim($value[1]);
    }
    return $response;
}
