This function will change new lines (line breaks) to <br/> and it allows you to limit the
amount of brs allowed at any point in time.
This function was made to avoid people spaming a textarea with hundreds of line breaks or empty
lines.
<?php
function nl2br_limit($string, $num){
$dirty = preg_replace('/\r/', '', $string);
$clean = preg_replace('/\n{4,}/', str_repeat('<br/>', $num),
preg_replace('/\r/', '', $dirty));
return nl2br($clean);
}
echo nl2br_limit($string,'4');
?>
// Heres how it works //
nl2br_limit($string, $num)
// $string is the entered text you want to strip lines out of, it could be
($_POST['myinput'])
// $num is the amount of consecutive <br/>'s that are allowed any at a time.
The user is allowed to enter as many line breaks as $num allows
