尝试以下代码：

$data = preg_replace('/([0-9]+)\)/', "<br/>", $data);
$data = array_filter(explode("<br/>", $data));
foreach ($data as $key => $val) {
    $val = str_replace("a)", " A)", $val);
    $val = str_replace("b)", " B)", $val);
    $val = str_replace("c)", " C)", $val);
    $val = str_replace("d)", " D)", $val);
