PHP highlight_string() not wrapping text

[Scott]

For some reason the code won't wrap when it is highlighted.

As you can see here, long strings won't wrap even though there are spaces and it has a set width.

That is because the function inserts one or more non-breaking-spaces ( ) for white-space characters (spaces and tabs) in the code.
These special characters will prevent the line from wrapping regardless of the CSS applied.

Here are your options:
- use CSS (overflow: auto;) to force scroll bars.
- use GeSHi for your syntax highlighting needs.

I would recommend the second option. GeSHi is very customisable and supports many more languages than just PHP.

I just used the overflow:auto; and it works now, thanks.

Good coding practice dictates line lengths should not be over a certain length anyway, e.g. 80 characters, but then, you probably won't be the only one writing the code to be submitted so either replace single   with an actual space or use a more suitable highlighter.

I never really liked highlight_string() for anything beyond trivial tasks anyway, even though many issues with it have been fixed, and besides, it only applies to PHP code which is not very useful for a tutorials site that will probably have code in many other languages, at least HTML.
