您不能像在 PHP 中那样将比较运算符串在一起。

改为尝试类似这里建议的方法https://stackoverflow.com/a/6920551/635522

编辑：考虑到我们希望在这里比较数组计数。

$arrays = [$_POST['name'],$_POST['alias'],$_POST['date'],$_POST['address'],...];

//create a second array with the lengths of all the arrays we want to compare
$lengths = [];
foreach($arrays as $array){
    $lengths[] = count($array);
}

//check if all the lengths are the same
if(count(array_unique($lengths)) == 1){
  // all match
}
