Question

<?php $lname = $_POST['lname'];
   if ( isset($_POST['lname'] )&& !empty( $_POST['lname'] ) ) {
      echo '<div class="result"My blank is under</div> <div class="green"> $lname </div> ';
   } else {
      echo '<div class="result">Please tell them your</div> <div class="green">last name!</div> ';
   }
?>

语法应该是正确的，但是当我将数据输入到我的表单中时，echo语句在绿色类中显示变量名$ lname而不是输入的数据。

我在某个地方忘记了引语还是逃到某个地方？

<style>
    .result {
        color: #FFF;
        display: block;
        font-size: 36px;
        margin-top: 1px;
        margin-before: 5px;
        margin-bottom: 0px;
        margin-start: 0; 
        margin-end: 0;
        text-align:center;
        font-weight: bold; }
    .green {
        color: #C9FF1F;
        display: block;
        font-size: 40px;
        margin-top: 1px;
        margin-before: 5px;
        margin-bottom: 0px;
        margin-start: 0;
        margin-end: 0;
        text-align: center;
        font-weight: bold;
    }
</style>

Answer 1

在PHP中，变量不使用单引号字符串进行插值;如果你想要这个功能，你需要做这样的事情：

echo "Hello $name";

而不是

echo 'Hello $name';

如果要使用单引号，请连接字符串，如下所示：

echo 'Hello ' . $name;
