html - 如何在选择选项的 HTML 标签中应用字体系列

Question

我在 <select><option> 申请字体系列标记，但它不起作用任何选项家伙

我的代码:

<select name="t1_font" class="form-control" >
   <option style="font-family: Font-familly path');">Font-family Name</option>
</select>

我正在使用的真实代码:

      <div class="col-sm-4">
  <?php $fonts=glob(FONT_URL.'*'); //print_r($fonts); ?>
  <?php if (!empty($fonts)): $i=0;?>
  <?php foreach ($fonts as $font):
    $font_arr= explode('/',$font); $font_string =substr($font_arr[3], 0, -4);?>
    <style>
    @font-face {
       font-family: <?php echo $font_string ?>;
       src: url('<?php echo $font ?>');
    }
    </style>
    <?php $i++;
    endforeach ?>
     <?php endif ?>
     <b>Family</b><br>
    <select name="t1_font" class="form-control" >
    <?php if (!empty($fonts)): ?>
      <?php foreach ($fonts as $font): $font_arr= explode('/',$font); $font_string =substr($font_arr[3], 0, -4); ?>
          <option style="font-family: <?php echo $font_string ?>;src: url('<?php echo base_url($font) ?>');" value="<?php echo $font_arr[3] ?>" <?php if(!empty($default_data_param->text1))
          {if($font_arr[3]== $default_data_param->text1_font_file){ echo'selected';}}?> ><?php echo ucfirst($font_string) ?></option>
      <?php endforeach ?>
    <?php endif ?>
    </select>
  </div>
