How to completely delete $_COOKIEs in PHP

Question

I have the following PHP script:

foreach( $_COOKIE as $key => $value ) {
  if( strpos( $key, 'ticketRecon_ID-' ) === false ) continue;
  else {
    setcookie( $key, '', time() - 1 );
    unset( $_COOKIE[$key] );
  }
}

When I run the script, print_r($_COOKIE) shows me the targeted cookies have been deleted and do not exist. Yet the Chrome dev tool inspector shows the cookies are still present (see screen shot below) And when I return to the page where the cookies where created they are still present.

How do you completely delete/erase/destroy a _COOKIE in PHP? Might this have any bearing or relation to the site pages using the SSL protocol?

AMENDED:

Here is how I initially set the cookie:

setcookie( 'ticketRecon_ID-' . $row['reservationID'], 'N', null, '/' );

Answer 1

Solved it.

It seems you must delete a _COOKIE the same exact and identical way you create them. So I was missing the path attribute on my delete setcookie() .

Created like this setcookie( 'ticketRecon_ID-' . $row['reservationID'], 'N', null, '/' );

So delete must be like this setcookie( $key, '', time() - 1, '/' );

Hope this post helps someone someday.

给它分配一个空数组

$_COOKIE = array();
