If you have ever tried to display code within a post you will know all about the problems this can cause. That is why there are some amazing developers who create plugins to make that solve this niggly issue.
I tried to list down the best code highlighter wordpress plugins for you. You can download one plugin out of 10 syntax highlighter plugins given below. I am using Syntax Highlighter Evolved in my tutorials.
SyntaxHighlighter Evolved allows you to easily post syntax-highlighted code to your site without having to escape the code or anything. It uses the SyntaxHighlighter JavaScript package by Alex Gorbatchev to do the highlighting and supports all of the package’s parameters via shortcode attributes.

This plugin do use of GeSHi highlight system, so you will have support for more then 110 languages, including PHP, ASP, Html, JavaScript, CSS, Java, Python, Delphi, C++, C, Visual Basic and much more.

This plugin displays the content of a file in a post. The content of the file (called a “snippet”) is put in a block by default.

This plugin supports the highlighting of PHP, HTML, CSS and XML. The default tag-highlighter color scheme uses the same colors Adobe’s Dreamweaver is using. This makes it easy for your visitors to recognize what type of codes you wrote. These colors can be changed to your liking in the WPadmin section of your blog.
