You need to define the size of file     header  Content-Length      filesize  file      And this line is wrong      header  Content-Disposition inline filename   filename      You messed up quotas

There are some things to be considered in your code   First  write those headers correctly  You will never see any server sending Content-type application pdf  the header is Content-Type  application pdf  spaced  with capitalized first letters etc   The file name in Content-Disposition is the file name only  not the full path to it  and altrough I don t know if its mandatory or not  this name comes wrapped in    not    Also  your last   is missing   Content-Disposition  inline implies the file should be displayed  not downloaded  Use attachment instead   In addition  make the file extension in upper case to make it compatible with some mobile devices   Update  Pretty sure only Blackberries had this problem  but the world moved on from those so this may be no longer a concern   All that being said  your code should look more like this    lt  php       filename      pdf jobs pdffile pdf         fileinfo   pathinfo  filename        sendname    fileinfo  filename           strtoupper  fileinfo  extension          header  Content-Type  application pdf        header  Content-Disposition  attachment  filename    sendname          header  Content-Length      filesize  filename        readfile  filename     Content-Length is optional but is also important if you want the user to be able to keep track of the download progress and detect if the download was interrupted  But when using it you have to make sure you won t be send anything along with the file data  Make sure there is absolutely nothing before  lt  php or after   gt   not even an empty line

Example 2 on w3schools shows what you are trying to achieve     lt  php header  Content-type application pdf        It will be called downloaded pdf header  Content-Disposition attachment filename  downloaded pdf         The PDF source is in original pdf readfile  original pdf      gt     Also remember that      It is important to notice that header   must be called before any   actual output is sent  In PHP 4 and later  you can use output   buffering to solve this problem
