如何在echo php中的html表单中显示php变量详细信息？

问题描述：

I have a form in which some I have defined some variables in PHP, The question is I need these variables details inside an html which is inside an echo . I don't know what to do as I have tried it.

   <?php $var= "LOVE" ?>
<!DOCTYPE html>
<html>
<head>
<title>Page Title</title>
</head>
<body>
 <?php echo "<!DOCTYPE html>
<html>
<head>
<title>Details</title>
</head>
<body>  
<div > <h1> echo $var ;</h1></div>
</body>
</html>";?>
</body>
</html>

我有一个表单，其中一些我在PHP中定义了一些变量，问题是我需要这些变量详细信息里面一个回声中的html。我不知道该尝试做什么。 p>

 ＆lt;？php $ var =“LOVE”？＆gt; 
＆lt;！DOCTYPE html＆gt; 
＆lt;  ; html＆gt; 
＆lt; head＆gt;

            <body>
                <div >
                    <h1>".$var."</h1>
                </div>
            </body>
        </html>";?>
    </body>
</html>

There is no need of adding <html>,<body> tags inside another. There is already one above in your code. I do not know why you have used this pattern.

You just need to write the variable on double quote. Here an example

<?php 
echo "<html>$var</html>"

// OR if one quote
echo '<html>'.$var.'</html>';
?>
