Question

I have a problem with a replacing characters, I do not know how to do that. We in Slovakia have characters with interpunctions.

How do I change (eg. á) for html code at input. If I have a string like Áno (translated yes), how do I change á to html code at the string.

I want make input where smiles like :-) will change to image. Or my interpunctioned characters to html code.

Answer 1

You can use strtr for such purposes. I do not know what problems you have to solve with smileys etc, so I'll give you an example for German umlauts (however not to HTML entities, but to standard ASCII characters):

$string = strtr($string, array('ä' => 'ae', 'ö' => 'oe', 'ü' => 'ue'));

Of course you can also use HTML entities instead of ae etc, you just have to look them up.

Edit

Judging from your update (I want make input where smiles like :-) will change to image. Or my interpunctioned characters to html code.) I think you want to use both htmlentities and strtr.

htmlentities will make sure that all non-ASCII characters are displayed correctly. Also have a look at UTF-8. With UTF-8, you will not have to translate your czech characters.

And strtr will replace your smileys by the proper HTML code.
