怎样使css样式 连接到一个PHP页中?

我写好了一个PHP页 和写好了CSS样式 但是不知道怎样使CSS样式在PHP页中起作用 
我是这样写连接的:<link rel=\"stylesheet\" href=\"style/style.css\" type=\"text/css\" /> 但是我不知道把这代码
放在PHP页中的哪个地方,我的PHP页代码结构是这样:<?php
                                              ......
                                               ?> 
                                              <html>
                                              ......
                                               <script..>
                                              .........
                                                </script>
                                                ...
                                               </html>
