试试这个:
<?PHP
$id=$_GET['id'];
?>
<!DOCTYPE>
<html>
<body>
<label>Package</label>
<input type="radio" name="package" value="pack" >
<label>Individual</label>
<input type="radio" name="package" value="ind" >
<div id="package" style=" display:none; height:100px; background-color:#a00; color:#fff;">
Display this div if PACKAGE is checked
</div>
<div id="individual" style=" display:none; height:100px; background-color:#a00; color:#fff;">
Display this div if INDIVIDUAL is checked
</div>
<?php if($id=='pack')
{
echo"checked";
echo"<script type=\"text/javascript\">";
echo"document.getElementById(\"package\").style.display=\"block\"";
echo"</script>";
} ?>
<?php if($id=='ind')
{
echo"checked";
echo"<script type=\"text/javascript\">";
echo"document.getElementById(\"individual\").style.display=\"block\"";
echo"</script>";
} ?>
</body>
</html>

你可以使用一点CSS和jQuery来完成客户端整个“点击广播节目/隐藏那个div”的事情。
$(document).ready(function () {
$("input[type=radio]").click(function () {
var showId = $(this).val() === 'pack' ? 'package' : 'individual';
var hideId = (showId === 'package') ? 'individual' : 'package';
$('#' + showId).show();
$('#' + hideId).hide();
});
});
这是DEMO
除了hide()和show()之外,您还可以使用toggle()或toggleClass()以及“show”或“隐藏”CSS类,正如Sudhir指出的那样。
这样的解决方案可以让你的代码更加清洁:)

你不需要js,你可以这样做, 创建css类
.hide {
display: none;
}
.show {
display: block
}
并在php文件中
$packChecked = ($id == "pack") ? "checked='checked'" : "";
$indChecked = ($id == "ind") ? "checked='checked'" : "";
$packClass = ($id == "pack") ? "show" : "hide";
$indClass = ($id == "ind") ? "show" : "hide";
then apply, like:
<input type="radio" name="package" value="pack" <?php echo $packChecked; ?> />
<div id="package" class="<?php echo $packClass; ?>">
...
</div>
//similarly for another radio button
