PHP function nl2br()

16. 02. 2020

Obsah článku

This function converts line breaks (`\n`) in a string to the HTML tag `
`.

Parameters

Parameter	Data type	Default value	Note
`$string`	`string`	not	Input string.
`$is_xhtml`	`bool`	`null`	Switches the escaping method according to the context.

Detailed description

$retezec = 'text
next text
and something else';

echo nl2br($retezec);

Returns:

text<br>
more text<br>
and something else

Converts broken lines in text to html tags. This tag is used in places where the user enters any text (textarea) and there is a risk of using multiple lines of text.

The treatment of classic inputs (type="text") is meaningless, as multi-line text cannot be entered here.

Note: As of PHP 4.0.5, the nl2br() XHTML function is eligible. All versions before 4.0.5 will return a string with a tag inserted before the line breaks instead of <br />.

Example

echo nl2br("Welcome\r\nThis is my HTML document", false);

Returns:

Welcome<br>
This is my HTML document

Return values

string

Returns an edited string including HTML tags.

Changes in versions

Version	Note
5.3.0	Added optional is_xhtml parameter.
4.0.5	`nl2br ()` is now XHTML compatible. All earlier versions will return a string with line breaks inserted instead of `<br />`.
