I have a perfectly working function

    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;

    }

But, on one particular site, using PHP 5.3.3, it's not working correctly.

On every other site I've tried it on I get

    Array
    (
[VPSProtocol] => 3.00
[Status] => 3DAUTH
[StatusDetail] => 2007 : Please redirect your customer to the ACSURL, passing the MD and PaReq.
[3DSecureStatus] => OK
[MD] => 201458812600945291

    )

but on the 5.3.3 server I get 

    Array
    (
        [VPSProtocol] => 3.00

    )

any suggestions or ideas gratefully received - I don't have access to the server to modify PHP but I do have enough access for PHP info etc.

EDIT

The string that I'm starting with always displays with working line breaks, eg

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

The developer docs I'm using say

Encoding will be as Name=Value fields separated by carriage-return-linefeeds (CRLF).

    Please show the raw non-mutated string. – Ohgodwhy Mar 26 '16 at 19:25
  • the line endings may differ and be `\n` or `\r\n` rather than just `\r` – iam-decoder Mar 26 '16 at 19:26

    @iam-decoder it's not \r - http://stackoverflow.com/a/2716436/1232318 "There is a little-known special character \R in preg_* regular exceptions that matches all three:" –  Mar 26 '16 at 19:31

In this case, this worked

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;

}
