值为string的PHP变量在PHP变量中不等于javascript中的html id值？

Question

This is my example code

<script>
    var item = "yooow";
    jQuery("#view").html(item);
</script>

<?php  $str_html = '<p id="view"></p>';

     echo $str_html; //it will output "yooow" 
?>

but...

when i'm trying to compare this into another php variable

<?php $str_php ="yooow";

    if($str_html == $str_php)
    {
         echo "true";
    }
    else
    {
        echo "false"; 
    }
?>

but it returns to false

how can they be an equal?

Better, you give the item value in cookie/session. And, compare the cookie value with $str_php.

<?php session_start(); ?>
<script>
$(document).ready(function(){
    var item = "<?php  echo $_SESSION['html']="yooow"; ?>";
    $("#view").html(item);
});
</script>
<?php  
    $str_html = '<p id="view"></p>';
    $strHtml=$_SESSION['html'];
    $str_php ="yooow";
    if($strHtml == $str_php)
    {
         echo "true";
    }
    else
    {
        echo "false"; 
    }
?>
