Can I display all the cookies I set in PHP?

You can display all cookies defined by running the following php function:
您可以通过运行以下 php 函数来显示所有定义的 cookie：
var_dump($_COOKIE);
回答by Manish
if($_COOKIE) {
print_r($_COOKIE); //print all cookie
}
else
{
echo "COOKIE is not set";
}

As with any inputs, security practices should include filtering and validation. Since all cookies are strings, sanitize the strings:
与任何输入一样，安全实践应包括过滤和验证。由于所有 cookie 都是字符串，因此请清理字符串：
var_dump(filter_input_array(INPUT_COOKIE, FILTER_SANITIZE_STRING, FILTER_REQUIRE_ARRAY))

if($_COOKIE) {
foreach ($_COOKIE as $key=>$val)
{
echo $key.' is '.$val."<br>\n";
}
}
else
{
echo "No Cookies are Set";
}
This will check if any cookies are set, if found will iterate through each and print out the cookie name and value
这将检查是否设置了任何 cookie，如果找到将遍历每个并打印出 cookie 名称和值
