title: Add quotes to values in a string separated by a comma php
body: <p>I have a search box that can contain multiple values using a comma, eg Pasta, tuna, eggs</p>
  
  <p>Im using FULLTEXT mysql search but I need to use some kind of preg_replace to turn Pasta, tuna, eggs into 'Pasta','tuna','eggs'</p>
  
  <p>If I enter this 'Pasta','tuna','eggs' into the search box the results are correct.</p>
