使用file_get_contents和希伯来字符串

Question

我需要file_get_contents()函数的帮助。

当我试图从包含一些希伯来字符的url中获取数据时，我从主机（无效链接）收到错误。

例如：

file_get_contents('http://domain.com/page/עברית'); 

不为我工作。

网址不能包含UTF-8字符。他们必须先进行网址编码。它们可能会在浏览器中显示为UTF-8字符，但这只是您的浏览器使它看起来更漂亮。

When a new URI scheme defines a component that represents textual 
data consisting of characters from the Universal Character Set [UCS], 
the data should first be encoded as octets according to the UTF-8 
character encoding [STD63]; then only those octets that do not 
correspond to characters in the unreserved set should be percent- 
encoded. For example, the character A would be represented as "A", 
the character LATIN CAPITAL LETTER A WITH GRAVE would be represented 
as "%C3%80", and the character KATAKANA LETTER A would be represented 
as "%E3%82%A2".
