For a WordPress technical blog on scripting languages, syntax highlighting is an important function to improve the readability of the code context. The readers can easily ignore large sections of comments and focus their attention on core codes. Thanks for WordPress plugin system, we can achieve the feature by installing any of the Syntax Highlighter Plugins.
1. WP Code Prettify

In the admin setting of the plugin, it’s very easy to select the style of highlighting – doxy,desert,prettify,sunburst or sons-of-obsidian.

3. WP-Syntax
WP-Syntax provides clean syntax highlighting for embedding source code within pages or posts.
WP-Syntax provides clean syntax highlighting using syntax highlighting library GeSHi . It supports a wide range of popular languages, highlighting with or without line numbers and maintaining formatting while copying snippets of code from the browser.
It avoids conflicts with other 3rd party plugins by running an early pre-filter and a late post-filter that substitutes and pulls the code snippets out first and then pushes them back in with highlighting at the end. The result is source code formatted and highlighted the way you intended.
