如何在php中添加链接

Question

嗨，我是一种新的网站和PHP。我正在尝试创建一个代码，告诉用户如果登录，或者如果用户注销，则显示注册/登录表单。下面是它的代码：

<?php  if(empty($_SESSION['user'])) 
     {echo " <a href=register.php >Register </a> Or <a href=login.php>Login</a>" ;   
     } 
     else{ 
     Hello htmlentities($_SESSION['user']['username'], ENT_QUOTES, 'UTF-8'); you currently have $_SESSION['user']['point']; points ! 
     }. ?> 

但它给我一个错误：

        PHP Error Message 

Parse error: syntax error, unexpected T_STRING in /home/a3897717/public_html/index1.php on line 63 

和第63行是这一个：

Hello htmlentities($_SESSION['user']['username'], ENT_QUOTES, 'UTF-8'); you currently have $_SESSION['user']['point']; points ! 

请如果有人能帮助我，请帮忙 ！ 在此先感谢！这不是重复，我只是想让别人告诉我我错在哪里，并纠正错误。

Answer 1

你搞砸了串联。

更改此：

echo "<a href=register.php >Register </a> Or <a href=login.php>Login</a>"; 

这样：

echo "<a href='register.php'>Register </a> Or <a href='login.php'>Login</a>"; 

这：

Hello htmlentities($_SESSION['user']['username'], ENT_QUOTES, 'UTF-8'); you currently have $_SESSION['user']['point']; points ! 

这样：

echo "Hello " . htmlentities($_SESSION['user']['username'], ENT_QUOTES, 'UTF-8') . "you currently have " . $_SESSION['user']['point'] . "points!"; 

编辑：

因为我无法找到一个在线的PHP/HTML编译器，以表明上面的代码工作我附上一张照片：

Note: It is obvious that the error is shown as the sessions are not defined and neither was the core problem of this question.

你错过了回音在输出字符串之前：

echo "Hello " . htmlentities($_SESSION['user']['username'], ENT_QUOTES, 'UTF-8'); 
echo "you currently have " . $_SESSION['user']['point']; 
echo "points !";
