Question

I need to change non-standard characters like ’ into standard ones like '. How can I do that in PHP? Right now I just need to change the apostrophe, but it would be nice to know how to change others like the double quote and such.

Answer 1

You can use str_replace():

$replace = array('’' => '\''); //You can add more characters here

echo str_replace(array_keys($replace), array_values($replace), 'can’t');

However, ’ and ' are two different characters and I would wonder why you would want to treat them as the same.
