title: Differences between PHPExcel and PHPExcelReader
body: <p>I'm on a project in my work where I have intended to read data from an .xls file. 
  I have seen the existence of some libraries, but it has generated some doubts.</p>
  
  <p>For example: PHPExcel and PHPExcelReader, are they the same?</p>
  
  <p>I have not found much documentation related to PHPExcelReader, that led me to doubt what is the use that is given to the library.</p>
  
  <p>The project I am about to make consists of a form you have to complete a field, from which complete data in the field, find if there is any column in the .xls file with that information.</p>
  
  <p>This is possible with PHPExcel or PHPExcelReader?</p>
