如何输出一个字符串，其中的换行符在php中可见？

Question

I have a string with newlines that I'd like to print out so that I see the special chars (such as ) rather than the newlines themselves.

So a string that would typically be echo'd as

this is the top line of my string
this is the second line of the string

Would instead look like this:

this is the top line of my string
this is the second line of the string

How could I accomplish this in php?

Answer 1

Try this:

<?php

$string = "this is the top line of my string
this is the second line of the string";

echo json_encode($string);

?>
