Have a look at urlencode().

Your solution is kind of an 'abuse' of ereg_replace() which accepts regular expressions and not plain strings. In regular expressions some characters have a special meaning. For example, a curly bracket introduces a repetition. But it needs to be followed by a number and a closing curly bracket. Hence the error message.

Some characters have special meaning in regular expressions.
Escape them with a backslash to tell regexp that you mean just the character.

I think I've got them all below...

$un = array('%',' ','{','}','~','<','>','!','"','\$','&','\+',',','/',':',';','=','\?','@');

str_replace is probably the best option here - or urlencode if that achieves what you want.
