問題描述
FILTER_VALIDATE_URL 過濾器在驗證非 ASCII 網(wǎng)址時似乎有一些問題:
The FILTER_VALIDATE_URL filter seems to have some trouble validating non-ASCII URLs:
var_dump(filter_var('http://pt.wikipedia.org/wiki/', FILTER_VALIDATE_URL)); // http://pt.wikipedia.org/wiki/
var_dump(filter_var('http://pt.wikipedia.org/wiki/Guimar?es', FILTER_VALIDATE_URL)); // false
為什么最后一個 URL 沒有正確驗證?可能的解決方法是什么?運行 PHP 5.3.0.
Why isn't the last URL correctly validated? And what are the possible workarounds? Running PHP 5.3.0.
我還想知道在哪里可以找到 FILTER_VALIDATE_URL 驗證過濾器的源代碼.
I'd also like to know where I can find the source code of the FILTER_VALIDATE_URL validation filter.
推薦答案
解析從這里開始:
http://svn.php.net/viewvc/php/php-src/trunk/ext/filter/logical_filters.c?view=markup
實際上是在/trunk/ext/standard/url.c 中完成的
and is actually done in /trunk/ext/standard/url.c
乍一看，我看不到任何有意拒絕非 ASCII 字符的內(nèi)容，因此可能只是缺少 unicode 支持.PHP 不擅長處理任何地方的非 ASCII 字符.:(
At a first glance I can't see anything that purposely rejects non-ASCII characters, so it's probably just lack of unicode support. PHP is not good in handling non-ASCII characters anywhere. :(
