The following functions are available:


Formats text so that it is semantically and typographically correct HTML. Takes a string as input and returns it with the following formatting:

Usage example:

$string = auto_typography($string);

Note: Typographic formatting can be processor intensive, particularly if you have a lot of content being formatted. If you choose to use this function you may want to consider caching your pages.


Converts newlines to <br /> tags unless they appear within <pre> tags. This function is identical to the native PHP nl2br() function, except that it ignores <pre> tags.

Usage example:

$string = nl2br_except_pre($string);
