Hiding a Div using php

I am currently hiding a div based on an if statement. The method I use is, use echo out a css style of display: none

Here is what I am doing specifically:

<style>
  #content{
    <?php
      if(condition){
          echo 'display:none';
      }
    ?>
  }
</style>
<body>
    <div id="content">
       Foo bar
    </div>
</body>

My question being, Is this a good method for a hiding a div? Is it possible that browser cache the style and therefore ignore the echo-ed out css style?
