    from php you can invoke jquery like this but my 2nd method is much cleaner and better for php

    if($switchView) :?>
 <script>$('.container').hide();</script>
 <script>$('.confirm').show();</script>
<?php endif;

    another way is to initiate your class and dynamically invoke the condition like this

    $registerForm ='block';

    then in your html use this 

    <div class="col" style="display: <?= $registerForm?>">

    now you can play with the view with if and else easily without having a messed code example

    if($condition)  registerForm = 'none';

    Make sure you use 'block' to show and 'none' to hide. This is far the easiest way with php

    You can use css or js for hiding a div. In else statement you can write it as:

    else{
?>
<style type="text/css">#divId{
display:none;
}</style>
<?php
}

    Or in jQuery

    else{
?>
<script type="text/javascript">$('#divId').hide()</script>
<?php
}

    Or in javascript

    else{
?>
<script type="text/javascript">document.getElementById('divId').style.display = 'none';</script>
<?php
}

    Use show/hide method as below

    $("div").show();//To Show

$("div").hide();//To Hide

    <?php
$divStyle=''; // show div

// add condition
if($variable == '1'){
  $divStyle='style="display:none;"'; //hide div
}

print'<div '.$divStyle.'>Div to hide</div>';
?>

    A fresh look at this(possibly)
    in your php:

    else{
      $hidemydiv = "hide";
}

    And then later in your html code:

    <div class='<?php echo $hidemydiv ?>' > maybe show or hide this</div>

    in this way your php remains quite clean

    Probably the easiest to hide a div and show a div in PHP based on a variables and the operator.

    <?php 
$query3 = mysql_query($query3);
$numrows = mysql_num_rows($query3);
?>
<html>
<?php if($numrows > null){ ?>
     no meow :-(
<?php } ?>

<?php if($numrows < null){ ?>
     lots of meow
<?php } ?>
</html>

    Here is my original code before adding your requirements:

    <?php 
$address = 'meow';
?>
<?php if($address == null){ ?>
     no meow :-(
<?php } ?>

<?php if($address != null){ ?>
     lots of meow
<?php } ?>
