title: PHP - Eclipse PDT - Highlighting uinitialized (misspelled) variables
body: <p>I use the wonderful Eclipse PDT for PHP development.</p>
  
  <p>I often encounter irritating bugs due to me misspelling variable names.</p>
  
  <p>Is there a way to highlight variables that have not been initialized? As they will almost certainly be due to a spelling mistake.</p>
  
  <p>Thanks for any help.</p>
