Question

I’m generating an XML from data that comes from database (and some JSON feeds).

I’m having some problems with some texts that contains some hex chars that are breaking my XML.

For example, see this screenshot of the error I get from Chrome:

I identified the hex characters that are giving me problems (I believe they’re called control characters). And these are:

0x03
0x05
0x16
0x0E

How can I replace those characters with PHP before printing them on my XML output?

Thanks!

Answer 1

More than just those characters will break it…

preg_replace('/[\x00-\x1f]/', '?', $s);
