I am not able to download zip file using php. Is there any solution to download zip file with its content. I can download but content is not showing. my tried code: if ((isset($file))&&(file_exists($dir.$file))) { header("Pragma: public"); header("Expires: 0"); header("Cache-Control: must-revalidate, post-check=0, pre-check=0"); header("Content-Description: File Transfer"); header('Content-Disposition: attachment; filename="'.$dir.$file.'"'); header("Content-Transfer-Encoding: Binary"); header("Content-length: ".filesize($dir.$file)); header("Content-Type: application/zip"); header('Content-Disposition:attachment;filename="'.$file.'"'); ob_clean(); flush(); readfile($dir.$file); } ---- Server IP: 202.65.157.132 Probable Submitter: 114.143.128.26 ---- Manual Page -- http://www.php.net/manual/en/faq.using.php Edit -- https://master.php.net/note/edit/102454 Del: integrated -- https://master.php.net/note/delete/102454/integrated Del: useless -- https://master.php.net/note/delete/102454/useless Del: bad code -- https://master.php.net/note/delete/102454/bad+code Del: spam -- https://master.php.net/note/delete/102454/spam Del: non-english -- https://master.php.net/note/delete/102454/non-english Del: in docs -- https://master.php.net/note/delete/102454/in+docs Del: other reasons-- https://master.php.net/note/delete/102454 Reject -- https://master.php.net/note/reject/102454 Search -- https://master.php.net/manage/user-notes.php
