如何目标数组的post使一行代码而不是多行？

Question

正如您所看到的，我需要为表单中的每个项目创建多行，我如何创建一行（我想我需要做的是针对整个post数组？）要包含整个$_POST，我的当前方法如下所示。

$name = trim(preg_replace('/ +/', ' ', preg_replace('/[^A-Za-z0-9 ]/', ' ',    urldecode(html_entity_decode(strip_tags($_POST['name']))))));
$email = trim(preg_replace('/ +/', ' ', preg_replace('/[^A-Za-z0-9 ]/', ' ', urldecode(html_entity_decode(strip_tags($_POST['email']))))));
$phone = trim(preg_replace('/ +/', ' ', preg_replace('/[^A-Za-z0-9 ]/', ' ', urldecode(html_entity_decode(strip_tags($_POST['phone']))))));
$make = trim(preg_replace('/ +/', ' ', preg_replace('/[^A-Za-z0-9 ]/', ' ', urldecode(html_entity_decode(strip_tags($_POST['make']))))));
$model = trim(preg_replace('/ +/', ' ', preg_replace('/[^A-Za-z0-9 ]/', ' ', urldecode(html_entity_decode(strip_tags($_POST['model']))))));
$year = trim(preg_replace('/ +/', ' ', preg_replace('/[^A-Za-z0-9 ]/', ' ', urldecode(html_entity_decode(strip_tags($_POST['year']))))));
$vin = trim(preg_replace('/ +/', ' ', preg_replace('/[^A-Za-z0-9 ]/', ' ', urldecode(html_entity_decode(strip_tags($_POST['vin']))))));
$insurance_company = trim(preg_replace('/ +/', ' ', preg_replace('/[^A-Za-z0-9 ]/', ' ', urldecode(html_entity_decode(strip_tags($_POST['insurance_company']))))));
$message = trim(preg_replace('/ +/', ' ', preg_replace('/[^A-Za-z0-9 ]/', ' ', urldecode(html_entity_decode(strip_tags($_POST['message']))))));
$IP = $_SERVER['REMOTE_HOST'] ?: gethostbyaddr($_SERVER['REMOTE_ADDR']);



 I use this to make  all the fields into one variable 
$combineall = $name . $email . $phone . $make . $model . $year . $vin . $insurance_company . $message . $message . $IP ;

而且

if (isset($_POST['submit'])){
Once the button is pressed cleans the all the fields in the post array. 
$combineall = trim(preg_replace('/ +/', ' ', preg_replace('/[^A-Za-z0-9 ]/', ' ', urldecode(html_entity_decode(strip_tags($combineall))))));

像这样的东西是我正在寻找的，但这不起作用，任何想法如何修复它？？？

$_POST = trim(preg_replace('/ +/', ' ', preg_replace('/[^A-Za-z0-9 ]/', ' ', urldecode(html_entity_decode(strip_tags($_POST))))));

创建一个字段列表并对其进行迭代。

$fields = ['name', 'email', 'phone', 'make', 'model', 'year', 'vin', 'insurance_company', 'message'];
$combineAll = '';
foreach($fields as $field) {
    $combineAll .= trim(preg_replace('/ +/', ' ', preg_replace('/[^A-Za-z0-9 ]/', ' ',    urldecode(html_entity_decode(strip_tags($_POST[$field] ?? ''))))));
}
$combineAll .= $_SERVER['REMOTE_HOST'] ?: gethostbyaddr($_SERVER['REMOTE_ADDR']);

若要迭代独立于键名的所有字段，可以按照下面的方法进行。但请注意，您无法控制不存在的键或顺序！

foreach($_POST as $field) {
    $combineAll .= trim(preg_replace('/ +/', ' ', preg_replace('/[^A-Za-z0-9 ]/', ' ',    urldecode(html_entity_decode(strip_tags($_POST[$field] ?? ''))))));
}
$combineAll .= $_SERVER['REMOTE_HOST'] ?: gethostbyaddr($_SERVER['REMOTE_ADDR']);
