title: PHPExcel - Read data from specific columns by header name?
body: <p>I have a project where the client uploads several XLS files and I need to grab the data only from the columns that he has named with specific headers (where header = data in first row). Sometimes they aren't even in the same order or they might be spread across the worksheet so I cant use a range.</p>
  
  <p>I was thinking of creating an array with the column names I want to read, scan the worksheet and find the column ids and start reading the worksheet with getCellByColumnAndRow(). 
  However, I feel that this might be like reinventing the wheel so I thought I'd ask if there are ready methods I'm unaware of.</p>
