Can't update cookie

[Drag1]

I tried to update cookie with php but it doesn’t work.
This is my code

<?php 
$id=58;
$cookiearray = $_COOKIE['content'];
$cookiearray = explode(",", $cookiearray); 
print_r($cookiearray);
$pos = array_search($id, $cookiearray);
echo '<br>Number 58 found at: ' . $pos; echo '<br>';
unset($cookiearray[$pos]); echo 'See if removed'; print_r($cookiearray); echo '<br><br>';
setcookie('content',$cookiearray,time()+31536000), '/');
echo 'Cookie values '.$_COOKIE['content']; ?>

I have cookie array $cookiearray that contains 3 numbers like that
Array ( [0] => 44 [1] => 57 [2] => 58 )

I goes well and ‘Number 58 found at: 2’

See if removed Array ( [0] => 44 [1] => 57 ) so it was successfully removed.
Then I do setcookie again and I get the old values when I echo it at the end.
Cookie values 44,57,58

Any idea why the cookie is not updated with new values 44,57?
Why setcookie doesn’t work?

Then I do setcookie again

You shouldn’t do any output before setcookie() call as it will not be able to send cookie header if output has been already started

I get the old values when I echo it at the end.

You’re removing value from $cookiearray but not from $_COOKIE. These two arrays don’t linked between each other.

I tried without print and it doesn’t work.

 <?php 
$id=58;
$cookiearray = $_COOKIE['content'];
$cookiearray = explode(",", $cookiearray); 
// print_r($cookiearray);
$pos = array_search($id, $cookiearray);
// echo '<br>Number 58 found at: ' . $pos; echo '<br>';
unset($cookiearray[$pos]); // echo 'See if removed'; print_r($cookiearray); echo '<br><br>';
setcookie('content',$cookiearray,time()+31536000), '/');
// echo 'Cookie values '.$_COOKIE['content']; ?>

You can’t update cookie by unset command. I read you can only set it up again with new values.
That’s the why I haven’t do unset on the cookie but tried to set cookie again with new values.

You should understand that when you call setcookie() it actually affects contents of $_COOKIE array only on the next page load, when cookies will be received again
