IE9 can’t open the php page, please help me, what should I do?

IE9 can’t open the php page, please help.
I write code in WAMP environment, and every time IE9 runs the php page, a download dialog pops up, but I can parse it normally with 360 browser! In addition, my IE9 always pops up a download dialog box for all other PHP pages on the Internet, but the 360 ​​can be displayed normally! What is the reason for this? I can’t find the reason after searching online. Can anyone help me? ? ? ? ? ?

For the url that always pops up a download dialog box when using IE9
You execute the following code:
$s = file_get_contents(‘real url’);
echo base64_encode(substr($s, 0, 100));
Post results

Or give a valid link

I know what’s going on,
The php.ini file configuration is incorrect, and the part of the dll file that loads the php extension is incorrect. Sir, you should check the PHP operating environment.
