我如何使用preg_match与字母数字和unicode接受？

I am going to build a multilingual website with PHP and need to have a preg_match which passes all Unicode characters and numbers.
i.e I need it to pass English letters, Spanish letters,Italian letters and as you may know I don't want to pass other characters like ' " _ - and ...

我打算用PHP构建一个多语言网站，需要有一个传递所有Unicode字符和数字的preg_match。即我需要它传递英文字母，西班牙文字母，意大利字母，你可能知道我不想传递其他字符，如'“_ - 和......

I want some thing like this :

我想要这样的事情：

$pattern='/^[unicode chars without \'-_;?]*$/u'; 
if(!preg_match($pattern, $url))
   echo #error;

Unicode property for letter is \pL so in preg_match:

字母的Unicode属性是\ pL所以在preg_match中：

preg_match('/^\pL+$/u', $string);

for an url you could add numbers \pN and dot:

对于网址，您可以添加数字\ pN和点：

preg_match('/^[\pL\pN.]+/u', $string);
