如何使用$ _SESSION ['username']打印彩色回声

Question

我无法在php $_SESSION['username']中为echo着色。

echo "Welcome, " .$_SESSION['username']."! "; //this code is running

echo '<span style="color:#AFA;text-align:center;">Welcome,'$_SESSION['username'];'</span>'; // this part is not working...

如果可以，请帮助我

Answer 1

您忘记了连结.。

echo '<span style="color:#AFA;text-align:center;">Welcome,' . $_SESSION['username'] . '</span>'; // this part is not working...

Answer 2

请注意.

之前和之后缺少的$_SESSION['username'];

echo'<span style="color:#AFA;text-align:center;">Welcome,'.$_SESSION['username'].'</span>';
