How to get IE to download PDF files instead of opening them directly

For example, there is a PDF file on a server: http://www.xxx.com/abc.pdf
Then ABC, click on the hyperlink under IE, will open the PDF file directly, how can I pop the download box under IE, instead of opening it directly? What do you do with PHP (or JS)?

oo.php

$file _path= ' test.pdf '; $file _name= ' test.pdf '; $fp =fopen ($file _path, "R"); $file _size=filesize ($file _path); Header (" Content-type:application/octet-stream "), Header (" Accept-ranges:bytes "), Header (" Accept-length: $file _size "); Header ("Content-disposition:attachment;filename=". $file _name); $buffer =1024; $file _count=0;while (!feof ($FP) & & ($file _size-$file _count>0) {$file _data=fread ($fp, $buffer); $file _count+= $buffer; echo $file _data;} Fclose ($FP);
