nl2br problem

[wmguk]

Hi,

 

I'm trying to restrict the output of lines. I used the code below, but then realised the entry in the DB doesnt have <br> anywhere...

 

How can i do this?

 

<?php

$maxlines = 5;

// see http://de2.php.net/manual/en/function.nl2br.php
$newtext = nl2br($text);

// explode the string 'seperated' by <br /> (or <br> for PHP < 4.0.5),
// but limited to the first $maxlines lines
$lines = preg_split('#<br( /)?>#', $newtext, $maxlines);

// stick them back together
$newtext = implode('<br />', $lines);

?>

I am not sure about this, but have you tried splitting by using "\n"  (width double quotes) as your string?

hmmm, couldnt get that to work,

 

if I remove the nl2br then I just get a rambling load of text, so there must be a way of converting it

 

Most confusing

[wildteen88]

nl2br converts newlines into <br /> tags. Eg it converts this

Some text here

Blah blah

What ever

 

To the following:

Some text here<br />
<br />
Blah blah<br />
<br />
What ever

 

If the text in your database doesn't have any new lines then your code will not work. You may want to limit the text by the number of words or characters instead.
