Arrays 如何将API响应数组字符串插入数据库

我正在尝试集成银行支付网关，在该网关中，数据提交和处理工作正常，但未将下面收到的成功响应插入数据库，因为它是一个数组形式的字符串

BRN=837740&STC=000&RMK=success&TRN=5230896525&TET=2020/02/08 11:54:18 PM&PMD=CD&RID=253357&VER=1.0&CID=3636&TYP=Test&CRN=802406&CNY=INR&AMT=10000.00

例如：在这个代码中，BRN是一个参数，837740是它的返回值，STC是参数，000是它的返回值

现在我想在php变量中设置所有这些值，以便插入到数据中，如果没有返回值，则应在db中为eg存储null

BRN=837741&STC=111&RMK=failure&TRN=1172146589&TET=&PMD=AIB&RID=126036&VER=1.0&CID=3636&TYP=Test&CRN=740076&CNY=INR&AMT=10000.00

我尝试了下面的代码，如果所有参数都返回了值，那么它就不能作为分隔符序列工作

$chunks = preg_split('/(=|&)/', $qStr,-1, PREG_SPLIT_NO_EMPTY);
    //print_r($chunks);

    echo '<pre>';
    print_r($chunks);
    echo '</pre>';
/*
    echo "<br>";
    echo "<br>";    

    $nweString = $chunks[0];
    for($i=1; $i<count($chunks); $i++) {
   // $nweString .= ':'.$chunks[$i];
    }
    echo $nweString;
    */


    echo "<br>";
    echo "<br>";
    echo "BRN = " . $BRN = $chunks[1] . "<br>";
//  echo "BRN = " . $BRN = $chunks[2] . "<br>";
    echo "STC = " . $STC = $chunks[3] . "<br>";
//  echo "BRN = " . $BRN = $chunks[4] . "<br>";
    if ($chunks[5] == "success") {$txtclr1 = '09CB00';}
    echo "<font color='$txtclr1'>" ."RMK = " . $RMK = $chunks[5]."</font>". "<br>";

    //echo "RMK = " . $RMK = $chunks[5] . "<br>";
    //echo "BRN = " . $BRN = $chunks[6] . "<br>";
    echo "TRN = " . $TRN = $chunks[7] . "<br>";
    //echo "TET = " . $BRN = $chunks[8] . "<br>";
    echo "TET = " . $TET = $chunks[9] . "<br>";
    //echo "BRN = " . $BRN = $chunks[10] . "<br>";
    echo "PMD = " . $PMD = $chunks[11] . "<br>";
    //echo "BRN = " . $BRN = $chunks[12] . "<br>";
    echo "RID = " . $RID = $chunks[13] . "<br>";
    //echo "BRN = " . $BRN = $chunks[14] . "<br>";
    echo "VER = " . $VER = $chunks[15] . "<br>";
    //echo "BRN = " . $BRN = $chunks[16] . "<br>";
    echo "CID = " . $CID = $chunks[17] . "<br>";
    //echo "BRN = " . $BRN = $chunks[18] . "<br>";
    echo "TYP = " . $TYP = $chunks[19] . "<br>";
    //echo "BRN = " . $BRN = $chunks[20] . "<br>";
    echo "CRN = " . $CRN = $chunks[21] . "<br>";
    //echo "BRN = " . $BRN = $chunks[22] . "<br>";
    echo "CNY = " . $CNY = $chunks[23] . "<br>";
    //echo "BRN = " . $BRN = $chunks[24] . "<br>";
    echo "AMT = " . $AMT = $chunks[25] . "<br>";

$chunks=preg_split（'/（=|&）/'，$qStr，-1，preg_split_NO_EMPTY）；
//打印（块）；

$nweString=$chunks[0]；
对于（$i=1；$i我在使用数组和爆炸函数后得到了答案

我的问题出了什么问题，没有人回答？？？
