If statement to change Div id

I'm writing some php/html code. I have a css file that has several backgrounds. Is there any way to write an if statement to select a div id depending on a php variable?

could do it in-line in your html/php

<div id="<?= ($true_or_false) ? 'div_id_1' : 'div_id_2' ?>">div content</div>

Or... if you have more than 2 div id options just do an classic if statement

<?php

if($condition) {
    $div_id = 'something';
}
else if ($another_condition) {
    $div_id = 'something_else';
}
..etc

?>

<div id="<?php echo $div_id ?>">div content</div>

// file: style.php
<?php
header("Content-Type: text/css");
?>

#mydiv {
  background: url('<?php

switch($_GET['background'])
  {
  case 1:
    echo 'blah1.jpg';
  //etc...
  }

?>');
}

Is this what you mean?

<?php
    $divId = $someBoolean ? "peaches" : "pineapples";
?>
<div id="<?php echo $divId ?>">Hello</div>

There are a few different ways you can do this. You can do it in php and assign a different class or id. Or you do it with javascript and change the class or id after the page loads.

You can generate CSS via PHP, first sort everything out and then print with text/css header.

<?php
header("Content-Type: text/css");
?>
*{margin:0;padding:0;}

Anyway you need to clarify your question.
