Question

/(<pre>|<code>|\[code])(.*)(</pre>|</code>|\[/code])/gi

This works if I have something such as:

<code>foobar</code>

But if I were to have a line-break like this:

<code>
    Awesome
</code>

It will not match it, what am I doing wrong?

Answer 1

You do need the DOTALL modifer /s, because the . dot per default excludes linebreaks.
The /g modifier OTOH is not legal in PHP and PCRE.

You should also use .*? to not match too wide.
