i'll elaborate comment. zip file contains valid zip stuff plus complete html document @ end. , don't mean you've added compressed html @ end—it's appended:
there's no way how happened code you've shared should obvious fix once you've aware of it.
educate guess - suppose have this:
if(file_exists($zip_name)){ // push download zip header('content-type: application/zip'); header('content-disposition: attachment; filename="'.$zip_name.'"'); readfile($zip_name); // remove zip file exists in temp path unlink($zip_name); } ?> <!doctype html> <head> ... you can instance finish script before running unwanted code:
unlink($zip_name); exit; ... or use if() constructs not run it:
if(file_exists($zip_name)){ // ... }else{ ?> <!doctype html> <head> <? }
