Cakephp消毒和特殊字符

Question

i'm using sanitize::paranoid on a string but i need to exclude a few special characters but it doesn't seem to work.

$content=sanitize::paranoid($content,array('à',' '));

I've changed the encoding of my file from ansi to utf8 but cakephp doesn't really like it so i need to find another way.

That array should contain the list of characters to exclude from sanitization, but it keep removing the "à" and i want those character in the final string.

Answer 1

Sanitize:paranoid is a simple preg_replace ($allow is just additional characters, escaped):

preg_replace("/[^{$allow}a-zA-Z0-9]/", '', $string);

As you can see, paranoid is quite paranoid... doesn't accept non-ascii letters by default.

The file where you had the à was probably saved in another encoding (working on windows?)

Anyway, if you want you can write a better filter by using /[^\p{L}]/u, which excludes letters in any lanaguage.
