使用htmlspeacialchars函数显示用户在使用空格和换行符输​​入时的数据

Question

I am using nl2br() function to add a line break and then htmlspeacialchars() but the code displays <br/> while it should have been a line break. I have tried to put htmlspeacialchars() above but same output is displayed. I'm fetching data from my database variable named blog while I'm displaying some code too viz "<li> or any other ".

$blog=htmlspecialchars($blog);
$blog=nl2br($blog);

and line break is echoed as:

<br />

And more over I don't want to use javascript.

Answer 1

I've found solution from How to use add line break using nl2br while using htmlspeacialchars
And they suggest using both functions in this way.As I was not able to realise what Don't panic suggested in his comment.

$text_even=nl2br(htmlspecialchars($text_uneven));
