How can I syntax highlight the output from the exec() function in PHP?

I'm fetching output from the exec() function and I would like to have some syntax highlighting in the results.

Raw output

Current output is raw:

* [35mmanu[m/etc/init.d/mast: line 105: /var/log/mast/mast-all.log: Permission denied 

Text such as [35m are color highlighting in shell context.

Goal

I want to do it in HTML, I already have a colored shell script.

The question A library to convert ANSI escapes (terminal formatting/color codes) to HTML has an answer to this question.

Solution

aha is a Ansi to HTML Adapter written in C. It's available in an Ubuntu package and on github theZiz/aha.

My code is then simply:

   exec("$command | aha", $output, $exitCode);
   foreach($output as $k => $line) {
       if ($line == '1') { continue; }
       echo "$line";
   }

Description

   aha takes SGR-colored Input and prints W3C conform HTML-Code.
   aha reads the Input from a file or stdin and writes HTML-Code to stdout.

There is some nice options:

• --black , -b: Black Background and white "standard color"
• --word-wrap , -w: Wrap long lines in the html file. This works with CSS3 supporting browsers as well as many older ones.
• --no-header , -n: Don't include header into generated HTML, useful for inclusion in full HTML files.
