相对于绝对网址进行转换(使用阿拉伯语)

Question

>我有这些函数 pakagehttp://nadeausoftware.com/articles/2008/05/php_tip_how_parse_and_build_urls

如果我们这样做，就放

$x =  url_to_absolute('http://al-mashhad.com/News/النيابة-تستمع-لأقوال-خالد-يوسف-في-بلاغه-ضد-أبو-إسم/141274.aspx','../../Media/News/2012/12/16/2012-634912584761067771-106.jpg');
var_dump($x);

它将返回假因为这些函数不支持阿拉伯语

特别是这个函数

问题是如何添加正则表达式以使其在 URL 中支持阿拉伯语

Answer 1

您显示的网址并不是真正的有效网址。URL 中只允许使用 ASCII 字符;其他任何事情，您都需要进行百分比编码。为了方便起见，浏览器无论如何都会显示正确的字符。

首先在 URL 上运行 urlencode()，这会将阿拉伯字符转换为%xx实体;然后在其上运行函数。

即使您这样做，现代浏览器也会自动显示阿拉伯字符。
