The following is the code that PHP restricts the page to be accessed only in Wechat's own browser.

The copy code is as follows:

$useragent = $_ SERVER ['HTTP_USER_AGENT']

If (strpos ($useragent, 'MicroMessenger') = false) {

Echo "No access to non-Wechat browsers"

} else {

Echo "Wechat browser allows access"

}

The copy code is as follows:

$useragent = addslashes ($_ SERVER ['HTTP_USER_AGENT'])

If (strpos ($useragent, 'MicroMessenger') = false & & strpos ($useragent,' Windows Phone') = false) {
