Our article is about the PHP function nl2br(), which is used to insert HTML line breaks before all newlines in a string. This function is useful for displaying text that includes newlines in HTML documents. In this article, we will discuss the syntax and usage of nl2br(), as well as provide some examples.

The nl2br() function is used to insert HTML line breaks before all newlines in a string. The syntax of the nl2br() function is as follows:

The function takes two parameters, $string and $is_xhtml. The $string parameter is the string to be processed, and the $is_xhtml parameter is an optional boolean value indicating whether to use XHTML syntax for the line breaks. If $is_xhtml is set to true, the function will insert <br /> tags for the line breaks. Otherwise, it will insert <br> tags.

Here is an example of how to use the nl2br() function:

<?php
$string = "Hello\nWorld!";
echo nl2br($string);
?>

In this example, we have a string variable $string containing some text with a newline. We use the nl2br() function to insert an HTML line break before the newline.

The output of this code will be:

Hello

World!

As you can see, the nl2br() function has inserted an HTML line break before the newline in the string.
