PHP setcookie() - how do I get '@' to be represented in the content?

Hi,

I am trying to set a cookie with an email address.  If I use this code:

<?php
setcookie('ThisIsATest','test@test.com');
?>

Open in new window


Then I get a cookie with the following:
Name: ThisIsATest
Content: test%40test.com

Is there a way to make that content value 'test@test.com'?

Thanks,
Rick

There is no need to escape @ signs. In fact, they shouldn't be.
What you did was right, and the values are automatically escaped by the browser (special symbols are converted to their corresponding % equivalent). It is stored that way, @ = %40. But this would not interfere with how you access them via PHP. Just remember to unescape() the cookie if you are accessing it via Javascript.

You can be sure that when you set: setcookie('test','something@something.here');
$_COOKIE['test'] is something@something.here

@ is a special sign, so you need to put a "\" in front of it:

setcookie('ThisIsATest','test\@test.com');

maybe define
<?php
$string="test@test.com" 
setcookie('ThisIsATest','$sting');
?>

Open in new window

Hi,

When using PHP to set cookies, just use the normal:
setcookie('test','hello@test.com');

Open in new window


When you want to access the cookie via PHP, just use:
echo $_COOKIE['test'];

Open in new window


However, the problem comes when you try to access the cookie using JavaScript.
Make sure you use unescape() before outputting the cookie. I've attached an example below:

<?php
setcookie('test','hello@world.com');
echo "Cookie set: " . $_COOKIE['test'] . '<br />JS: ';
echo "<script type=\"text/javascript\">document.write(document.cookie)</script>";
?>

Open in new window


Make sure that you reload the page during your first run to see the results - it will be empty during your first run. Cookies are not accessible in the document right after you set them because cookies rely on the browser requests, and in that connection, the browser just received the cookie and it is already finished sending the requests.

I forgot to show the example about unescape:

<?php
setcookie('test','hello@world.com');
echo "Cookie set: " . $_COOKIE['test'] . '<br />JS normal: ';
echo "<script type=\"text/javascript\">document.write(document.cookie)</script>";
echo "<br />JS unescaped: <script type=\"text/javascript\">document.write(unescape(document.cookie))</script>";
?>

Thanks for the answers, but perhaps I need to clarify.

<?php

$name = 'test';
$content = 'test@test.com';

setcookie($name,$content);
setcookie('test2','test2\@test.com');
setcookie('test3','test3@test.com');

echo "test = " . $_COOKIE[$name] . "<br />";
echo "test2 = " . $_COOKIE['test2'] . "<br />";
echo "test3 = " . $_COOKIE['test3'] . "<br />";

?>

Open in new window


Yields the following output:

test = test@test.com
test2 = test2\@test.com
test3 = test3@test.com

But when I view the cookies in Firefox using Tools>>Options>>Privacy>>View Cookies, then I see those urlencoded values ('@' >> %40, etc).  

I see that other cookies are storing these characters un-urlencoded, and I was wondering if I can do that using PHP.  It may be that those other cookies are created with other technologies.

Thanks,
Rick
