Keyword Suggestor in PHP 5

To add a feature like Google's Did You Mean in your PHP application a reasonable solution is to use PHP's pspell library.

This comes bundled with PHP (http://php.net/pspell). Compile PHP with the '--with-pspell' option but before this ensure that you have aspell (version 0.6 or above) already installed.

Custom dictionary can also be created for aspell but this will require the aspell-lang package. You can download the same from here.

Details on how to create your custom dictionary are available here under the 'Creating a Custom Language Dictionary' section.
