how to delete all cookies of my website in php

Viewed 69 times

I'm wondering if I can delete all my website's cookies when a user click on logout, because I used this as function to delete cookies but it isn't work properly:

setcookie("user",false);

Is there a way to delete one domain's cookies in PHP?

PHP setcookie()

Taken from that page, this will unset all of the cookies for your domain:

// unset cookies
if (isset($_SERVER['HTTP_COOKIE'])) {
    $cookies = explode(';', $_SERVER['HTTP_COOKIE']);
    foreach($cookies as $cookie) {
        $parts = explode('=', $cookie);
        $name = trim($parts[0]);
        setcookie($name, '', time()-1000);
        setcookie($name, '', time()-1000, '/');
    }
}

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>

function getSubclassesOf($parent) {
    $result = array();
    foreach (get_declared_classes() as $class) {
        if (is_subclass_of($class, $parent))
            $result[] = $class;
    }
    return $result;
}

Coincidentally, this implementation is exactly the one given in the question linked to by Vadim.

Using the in-php-array-is-the-duct-tape-of-the-universe way :P

function get_all_substrings($input, $delim = '') {
    $arr = explode($delim, $input);
    $out = array();
    for ($i = 0; $i < count($arr); $i++) {
        for ($j = $i; $j < count($arr); $j++) {
            $out[] = implode($delim, array_slice($arr, $i, $j - $i + 1));
        }       
    }
    return $out;
}

$subs = get_all_substrings("a b c", " ");
print_r($subs);
