I'm playing around with cookies. And I dont have any cookies called PHPSESSID.
Do i need it? Can i remove it?
Whats the "function" of it?
if (count($_POST)) {
setcookie("TestCookie", htmlspecialchars($_POST['val']), time()+3600);
}
print_r($_COOKIE);
Prints:
Array
(
[TestCookie] => blabla
[PHPSESSID] => el4ukv0kqbvoirg7nkp4dncpk3
)
Use glob :
if (count(glob("path/*")) === 0 ) { // empty
A nice thing about glob is that it doesn't return . and .. directories.
Try using setcookie with a a path specified, this used to catch me out, as it assumes the current path by default. Using / will make the cookie work for the whole domain
setcookie("Username", $username, time()+3600*24*30, '/');
<?php
$cookie_name = "test";
$cookie_value = "123";
setcookie($cookie_name, $cookie_value, time() + (86400 * 30), "/"); // 86400 = 1 day
?>
You need to write your php code like this
You can use this script If u can want particular cookie
<script>
function getCookie(cname) {
var name = cname + "=";
var ca = document.cookie.split(';');
for(var i=0; i<ca.length; i++) {
var c = ca[i];
while (c.charAt(0)==' ') c = c.substring(1);
if (c.indexOf(name) == 0) return c.substring(name.length,c.length);
}
return "";
}
console.log(getCookie('test'));
<script>
It's very easy:
not all(t1)
returns False only if all values in t1 are non-empty/nonzero and not None. all short-circuits, so it only has to check the elements up to the first empty one, which makes it very fast.
PHP uses one of two methods to keep track of sessions. If cookies are enabled, like in your case, it uses them.
If cookies are disabled, it uses the URL. Although this can be done securely, it's harder and it often, well, isn't. See, e.g., session fixation.
Search for it, you will get lots of SEO advice. The conventional wisdom is that you should use the cookies, but php will keep track of the session either way.
