html - Trouble embedding PHP within CSS styled radio buttons to populate a form -

i'm writing programme allows info in database edited populating web form.

however, web page formatted customized radio buttons , seem having problem embedding php within html tags. understanding combinations of css , html don't allow php written inside. problem here? (the document saved php file)

<div id="radio4"> <div class="radio1" > <input id="mgender" type="radio" name="gender" value="m" <?php echo ($gender == 'm') ? "checked" : "" ; ?>> <label for="mgender"></label></div></div> <div id="radio5"> <div class="radio2"> <input id="fgender" type="radio" name="gender" value="f" <?php echo ($gender == 'f') ? "checked" : "" ; ?>> <label for="fgender"></label></div></div>

if so, how can prepare it?

try regular look :

<div id="radio4"> <div class="radio1" > <input id="mgender" type="radio" name="gender" value="m" <?php if($gender=='m'){echo"checked";}?> /> <label for="mgender">male</label></div></div> <div id="radio5"> <div class="radio2"> <input id="fgender" type="radio" name="gender" value="f" <?php if($gender=='f'){echo"checked";}?> /> <label for="fgender">female</label></div></div>
