nl2br — Dizgedeki tüm satırsonlarının yerine HTML satır katlayıcıları yerleştirilir
dizge içindeki bütün satırsonu karakterlerinin
(\r\n, \n\r, \n ve

Örnek 1 - nl2br() örneği
<?php
echo nl2br("foo isn't\n bar");
?>Yukarıdaki örneğin çıktısı:
foo isn't<br /> bar
Örnek 2 - xhtml bağımsız değişkeni kullanımı
<?php
echo nl2br("Hoş Geldiniz\r\nBu bir HTML belgedir", false);
?>Yukarıdaki örneğin çıktısı:
Hoş Geldiniz<br> Bu bir HTML belgedir
Örnek 3 - Çeşitli satırsonu ayraçları
<?php
$string = "This\r\nis\n\ra\nstring\r";
echo nl2br($string);
?>Yukarıdaki örneğin çıktısı:
This<br /> is<br /> a<br /> string<br />
It's important to remember that this function does NOT replace newlines with <br> tags. Rather, it inserts a <br> tag before each newline, but it still preserves the newlines themselves! This caused problems for me regarding a function I was writing -- I forgot the newlines were still being preserved.
If you don't want newlines, do:
<?php
$Result = str_replace( "\n", '<br />', $Text );
?>to replace all linebreaks to <br />
the best solution (IMO) is:
<?php
function nl2br2($string) {
$string = str_replace(array("\r\n", "\r", "\n"), "<br />", $string);
return $string;
}
?>
because each OS have different ASCII chars for linebreak:
windows = \r\n
unix = \n
mac = \r
works perfect for meHere's a more simple one:<?php/** * Convert BR tags to nl * * @param string The string to convert * @return string The converted string */function br2nl($string){ return preg_replace('/\<br(\s*)?\/?\>/i', "\n", $string);}?>EnjoyStarting from PHP 4.3.10 and PHP 5.0.2, this should be the most correct way to replace <br /> and <br> tags with newlines and carriage returns.<?php/** * Convert BR tags to newlines and carriage returns. * * @param string The string to convert * @return string The converted string */function br2nl ( $string ){ return preg_replace('/\<br(\s*)?\/?\>/i', PHP_EOL, $string);}?>(Please note this is a minor edit of this function: http://php.net/nl2br#86678 )You might also want to be "platform specific", and therefore this function might be of some help:<?php/** * Convert BR tags to newlines and carriage returns. * * @param string The string to convert * @param string The string to use as line separator * @return string The converted string */function br2nl ( $string, $separator = PHP_EOL ){ $separator = in_array($separator, array("\n", "\r", "\r\n", "\n\r", chr(30), chr(155), PHP_EOL)) ? $separator : PHP_EOL; // Checks if provided $separator is valid. return preg_replace('/\<br(\s*)?\/?\>/i', $separator, $string);}?>double quotes !== single quotesphp > echo nl2br('\r\n');\r\nphp > echo nl2br("\r\n");<br />Seeing all these suggestions on a br2nl function, I can also see that neither would work with a sloppy written html line break.. Users can't be trusted to write good code, we know that, and mixing case isn't too uncommon.I think this little snippet would do most tricks, both XHTML style and HTML, even mixed case like <Br> <bR /> and even <br > or <br />.<?phpfunction br2nl($text){ return preg_replace('/<br\\s*?\/??>/i', '', $text);}?>
