Php 如何使用isset和运算符作为一个三元语句

在三元语句中是否有一种执行三元语句的方法。比如说

@if (isset($checking))
<input type="radio" id="box" name="form" value="10"
{{$checking->myvalue == 10.0 ? 'checked' : ''}}/>
<label class="sister" for="boxwindow" title="myvalue_10" </label>
@else
<input type="radio" id="box" name="form" value="10"/>
<label class="sister" for="boxwindow" title="myvalue_10" </label>
@endif               

@if（设置（$checking））
myvalue==10.0？“选中“：”}}/>
试试这个

$foo = 1;
$bar = ($foo == 1) ? "1" : (($foo == 2)  ? "2" : "other");
echo $bar;

您可以尝试以下方法：

<input type="radio" id="box" name="form" value="10"
isset($checking->myvalue) == 10.0 ? 'checked' : ''}}/>
<label class="sister for="boxwindow" title="myvalue_10" </label>             

{{ isset($checking->myvalue) && $checking->myvalue == 10 ? 'checked' : '' }}



<?php echo isset($formData['employer_name'])?$formData['employer_name']:'_________________'; ?>

(isset($checking->myvalue) && $checking->myvalue == 10)?'checked' : '';
