PHP download DOC garbled code?

I recently built a system that required downloading the doc file

After the previous code was downloaded, it was always garbled when opened...

I haven’t found it on Google for a long time. Solution

Finally got it done later

Must be cleaned before Header, that is, ob_end_clean()

$file_size = filesize($logName); ob_end_clean(); header("Content-type:application/octet-stream"); header("Accept-Ranges:bytes"); header("Accept-Length:$file_size"); header("Content-Disposition:attachment;filename=" . $fileName); $fp = fopen($logName, "r"); $buffer_size = 1024; $cur_pos = 0; while (!feof($fp) && $file_size - $cur_pos > $buffer_size) { $buffer = fread($fp, $buffer_size); echo$buffer; $cur_pos+=$buffer_size; } $buffer = fread($fp, $file_size - $cur_pos); echo$buffer; fclose($fp); return true;
