Yes, it is possible.

You can serve a css file with php by setting the content-type.

<?php header('content-type: text/css; charset=utf-8'); ?>

You would output the css from the php file.

You could store values in a mySQL or other table with a form, and later retrieve them with the mySQLi or other library.

This is an example of the php script:

<?
    header('content-type: text/css; charset=utf-8');

    $bgColor = "#FFF"; // Get it from database, I'm setting manually for this example
?>

body{
      background-color:<?php echo "$bgColor" ?>;
}

Alternatively, you could output inline css on the page. Either directly in to a tag, or inline on elements.

If really needed a native css file for some reason (I can't think of one), you could technically overwrite a specific css file using php's fwrite() function, though I wouldn't recommend doing it this way.

 <?php

      $filename = "phpstyle.css";

      $fp = fopen($filename, 'w');

      $bgcolor = "#FFF";

      $css  = "body{";
      $css .= "background-color:".$bgcolor.";"; 
      $css .= "}";           

      fwrite($fp, $css);

      fclose($fp);

 ?>
