                <td width="51"><img src="/static/imghw/default1.png"  data-src="/app/webroot/emails/default/SingleProperty/Icon_Bed.jpg"  class="lazy"      style="max-width:90%"  style="max-width:90%" alt="Bedrooms" /></td>                <td width="25" style="font-family: Arial, Helvetica, sans-serif; font-size: 16px; font-weight: bold; color: #93bb3e;">4</td>                <td width="52"><img src="/static/imghw/default1.png"  data-src="/app/webroot/emails/default/SingleProperty/Icon_Bath.jpg"  class="lazy"      style="max-width:90%"  style="max-width:90%" alt="Bathrooms" /></td>                <td width="25" style="font-family: Arial, Helvetica, sans-serif; font-size: 16px; font-weight: bold; color: #93bb3e;">2</td>                <td width="48"><img src="/static/imghw/default1.png"  data-src="/app/webroot/emails/default/SingleProperty/Icon_Car.jpg"  class="lazy"      style="max-width:90%"  style="max-width:90%" alt="Car Spaces" /></td>                <td width="25" style="font-family: Arial, Helvetica, sans-serif; font-size: 16px; font-weight: bold; color: #93bb3e;">1</td>              </tr>            </table></td>            <td align="right" valign="middle"><table width="374" border="0" cellspacing="0" cellpadding="0">              <tr>                <td width="361" align="right"><span style="color: #999;	font-family: Arial, Helvetica, sans-serif; font-size: 16px;">Bellevue Hill</span> - <span style="color: #78aa0e; font-family: Arial, Helvetica, sans-serif;	font-size: 16px; font-weight: bold;">$850,000</span></td>                <td width="13"> </td>              </tr>

去掉所有的 font-size: XXpx;   XX不固定

回复讨论(解决方案)

$content_html = preg_replace('/font-size:.*px;/','',$content_html);

自己试出来了。。
