如何将多行表格数据传递给数组？表单未传递数组中的字符串

Question

这是我可以放置多行的简单形式<form action="" method="POST" name="domains">     <textarea name="message" rows="" cols="" name="domains" ></textarea>      <br></br>      <input type="submit"> <br></br>    <br></br>    </form>代码：<?PHP$domains= $_POST['domains'];$url = 'the API url';这是令人困惑的部分。我如何将这些多行表单数据放入这个数组？$query = http_build_query(array(        'domains' => array(            $domain = explode("\n",$string)        )    ));$url = $url .'?'. $query;$ch = curl_init();$header = array('Content-Type: multipart/form-data');$headers = ['API-OPR: apikey '];curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);curl_setopt($ch, CURLOPT_URL, $url);curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);$output = curl_exec ($ch);echo $output; curl_close ($ch);$output = json_decode($output,true);?>

Answer 1

按换行符展开$domains以使其阵列工作

$domains=  explode("\n",$_POST['domains']);
