Complicated case of escaping quotation marks

Here is the code I am trying to make work. As you can see, the code as it stands will call a javascript window and that works well. I now want to add the lines that are commented out, in order to make the window display or not display conditionally. I have tried many combinations of escaping quotation marks, or substituting them, but nothing works properly. Usually I lose the link action along with a display of some of the code attached to the link. Could someone have a look and see if they can propose a code solution.

<?php
//if ($review != 0) 
    //$yes2 =  

if ("{$row['passState']}" == 0) {echo "<a href='javascript<b></b开发者_如何学Python>:void(0);'NAME='var basestring='window'+new Date().getTime();' title=' Results of quiz 'onClick=window.open('check/check.php?quizTitle=". urlencode($quizTitle) ."', 'width=1100, height=510, resizable=yes, menubar=no, status=0, scrollbars=1');> <p>Check your answers</p> </a><br />\n";} 


    //echo $yes2;                   
    //if ($review != 1)
    //echo "";
    ?>

If it is any help, I'm using this code elsewhere on the page and it works fine.

<?php                   
 if ($review != 0) 
    $yes2 = "REVIEW";
    echo $yes2;                 
    if ($review != 1)
    echo ""; 
    ?>

if ("{$row['passState']}" == 0) {echo "<a href='javascript<b></b>:void(0);' NAME=\"var basestring='window'+new Date().getTime();\" title=' Results of quiz ' onClick=window.open('check/check.php?quizTitle=\". urlencode($quizTitle) .\"', 'width=1100, height=510, resizable=yes, menubar=no, status=0, scrollbars=1');> <p>Check your answers</p> </a><br />\n";}

Copy this as it is....

There's no need for all the escapes, you should embed the PHP code in the HTML, not the other way around. Example:

<?php if ($row['passState'] == 0): ?>

<p>
    <a href="javascript:your_code()">
        Check your answers
    </a>
</p>
<br />

<?php endif; ?>

I had a hard time deciphering what your javascript was trying to actually do, but this will make it a lot easier for you to read and write HTML without worrying about escaping quotes, using \n characters, etc.

You can use addslashes method to escape quotes

PHP Manual

Your onClick needs to have a quote(s) after the =:

...f quiz' onClick=\'window.open('check/check.php?quizTitle=". urlencode($quizTitle) ."',
