Fsockopen cannot obtain the webpage correctly, and a 403 error is returned.

Fsockopen cannot obtain the webpage correctly. if the fsockopen function of php returns error 403, other webpages can be obtained normally, but check. ptlogin2.qq. comcheck? Regmaster & amp; uin1_872340 & amp; appid549000912 & amp; js_ver10049 & amp; js_type1 & amp; login _ fsockopen cannot obtain the webpage correctly, and error 403 is returned.
Php's fsockopen function can normally get other web pages, but get http://check.ptlogin2.qq.com/check? Region % 3 Fpara % 3 Dizone & r = 0.42962526359176423
The error 403 is returned.

If the server is on the local machine and the local machine can access the page normally, it can be seen that the website is blocked by IP addresses. Suspected to be a problem with fsockopen

I would like to ask experts if they can use the fsockopen function to obtain the webpage correctly!
