php - 如何将字符串/数据库变成变量

Question

我在这里遇到了一些问题。我想让一个字符串成为一个变量，

$query = mysql_query("SELECT * FROM users Where username = 'fahmi'");
$result = mysql_fetch_array($query);

数组的结果是 - $result['data']="$a"

$a = "This is a Result 1" ;
$b = "This is a Result 2" ;
$c = "This is a Result 3" ;

$final = $result['data'];
echo $final;

当我运行这段代码时，结果是 $a 但我想要的结果是 "This is a result 1"，请帮助我，谢谢...

如果你想要可变变量，你可以这样实现:

$$a = "This is a Result 1" ;
$$b = "This is a Result 2" ;
$$c = "This is a Result 3" ;
