note 102175 added to function.header

I've written this function so many times, but every time I find a new problem - this one is working in all browsers. function downloadFile( $fullPath ){ // Must be fresh start if( headers_sent() ) die('Headers Sent'); // Required for some browsers if(ini_get('zlib.output_compression')) ini_set('zlib.output_compression', 'Off'); // File Exists? if( file_exists($fullPath) ){ // Parse Info / Get Extension $fsize = filesize($fullPath); $path_parts = pathinfo($fullPath); $ext = strtolower($path_parts["extension"]); // Determine Content Type switch ($ext) { case "pdf": $ctype="application/pdf"; break; case "exe": $ctype="application/octet-stream"; break; case "zip": $ctype="application/zip"; break; case "doc": $ctype="application/msword"; break; case "xls": $ctype="application/vnd.ms-excel"; break; case "ppt": $ctype="application/vnd.ms-powerpoint"; break; case "gif": $ctype="image/gif"; break; case "png": $ctype="image/png"; break; case "jpeg": case "jpg": $ctype="image/jpg"; break; default: $ctype="application/force-download"; } header("Pragma: public"); // required header("Expires: 0"); header("Cache-Control: must-revalidate, post-check=0, pre-check=0"); header("Cache-Control: private",false); // required for certain browsers header("Content-Type: $ctype"); header("Content-Disposition: attachment; filename=\"".basename($fullPath)."\";" ); header("Content-Transfer-Encoding: binary"); header("Content-Length: ".$fsize); ob_clean(); flush(); readfile( $fullPath ); } else die('File Not Found'); } ---- Server IP: 69.147.83.197 Probable Submitter: 71.204.87.158 ---- Manual Page -- http://www.php.net/manual/en/function.header.php Edit -- https://master.php.net/note/edit/102175 Del: integrated -- https://master.php.net/note/delete/102175/integrated Del: useless -- https://master.php.net/note/delete/102175/useless Del: bad code -- https://master.php.net/note/delete/102175/bad+code Del: spam -- https://master.php.net/note/delete/102175/spam Del: non-english -- https://master.php.net/note/delete/102175/non-english Del: in docs -- https://master.php.net/note/delete/102175/in+docs Del: other reasons-- https://master.php.net/note/delete/102175 Reject -- https://master.php.net/note/reject/102175 Search -- https://master.php.net/manage/user-notes.php
