Spelling correction
<p>How to implement this in PHP ?</p>

<p>We are developing a small application which requires to find the correct search keywords if there is any spelling mistakes. For example, If i search for "where to buy electrive cooker" in Google, I will get the result, "where to buy electric cooker". It will show the line like
Showing results for where to buy electric cooker. plz note the spelling mistake electrive instead of electric</p>

<p>So, I would like to implement the same. Whenever any user searches with spelling mistake. I should be able to give the result for correct Keyword.</p>
