PHP无法读取javascript cookie

I am setting a cookie with javascript and trying to read it with PHP, but php is not able to read it. I have checked that the cookie is really set with a tool called Cookies Manager.

Code(JS):

<script>
document.cookie="encrIv=" + ivB64;
</script>

Code(PHP):

<?php
$encrIv = $_COOKIE['encrIv'];
echo $encriv;
?>

I get

Notice: Undefined index: encrIv in C:\Users\joonas\Desktop\Webon cmsooteadCookie.php on line 1

Screen shot of cookie:

    <!DOCTYPE html>
<html>
  <head>
    <title>example</title>
    <script type="text/javascript">
       document.cookie = 'name=David' ;
    </script>
   </head>
   <body>
    <?php
       var_dump($_COOKIE['name']);
    ?>
   </body>
 </html>

    with this the cookie is set. Did you correct your Typo? You wrote:

    <?php
$encrIv = $_COOKIE['encrIv'];
echo $encriv;
?>

    the correct way is to change the echo to

    echo $encrIv;

    or to change your variable to 

    $encriv = $_COOKIE['encrIv'];

    EDIT:

    Maybe your Problem is the not defined Path. define a cookie like this:

    document.cookie = 'sconName='+changedName+'; path=/'
