In the day to day job I am involved with reading code or sometimes writhing it and sometimes it can be hard to read or write the code if is not properly formatted. Along the years I tried some of the syntax highlighter plugins to ease my work on the sites that I have were I am posting different content. Below I will present the best syntax highlighter plugins for WordPress so you can chose the perfect one for you.
