php - How to replace text over multiple lines using preg_replace

Question

Hi have the following content within an html page that stretches multiple lines

<div class="c-fc c-bc" id="content">
                <span class="content-heading c-hc">Heading 1 </span><br />
                The Home Page must provide a introduction to the services provided.<br />
                <br />
                <span class="c-sc">Sub Heading</span><br />
                The Home Page must provide a introduction to the services provided.<br />
                <br />
                <span class="c-sc">Sub Heading</span><br /> 
                The Home Page must provide a introduction to the services provided.<br />
            </div>

I need to replace everthing between <div class="c-fc c-bc" id="content"> and </div> with custom text

I use the following code to accomplish this but it does not want to work if it's multiple lines, but works if evertinh is in one line

$body = file_get_contents('../../templates/'.$val['url']);

$body = preg_replace('/<div class="c-fc c-bc" id="content">(.*)</div>/','<div class="c-fc c-bc" id="content">abc</div>',$body);

Am I missing something?

If this weren't HTML, I'd tell you to use the DOTALL modifier to change the meaning of . from 'match everything except new line' to 'match everything':

preg_replace('/(.*)</div>/s','abc',$body);

But this is HTML, so use an HTML parser instead.
