After PHPsetcookie specifies the domain parameter, set the cookie failure solution in IE

After the setcookie function specifies the domain parameter, the performance in IE is different from that in chrome and firefox. this is not a problem with the phpsetcookie function, which is a problem with IE. The following code generates three cookies in chrome and firefox:
Cookie [one], cookie [two], cookie [three]
In IE, only two cookies, namely [one] and [two], can be generated. The third cookie [three] fails to be generated because ". 65. la" is specified.
Copy codeThe code is as follows:
Setcookie ("cookie [one]", "cookieone", time () + 36000 ,"/");
Setcookie ("cookie [two]", "cookietwo", time () + 36000 ,"/");
Setcookie ("cookie [three]", "cookiethree", time () + 36000, "/", ". 65. la ");
// Repeat the page
If (isset ($ _ COOKIE ["cookie"]) {
Foreach ($ _ COOKIE ["cookie"] as $ name => $ value ){
$ Name = htmlspecialchars ($ name );
$ Value = htmlspecialchars ($ value );
Echo "$ name: $ value
\ N ";
}
}
?>

After many experiments, I confirmed that the domain name parameters in the form of ". 65. la" were not standardized by IE. If you want to use cookies for all subdomain names, you can use global variables.
