使用正则表达式从字符串中删除额外的行

Question

My string is having text like this;

TEXT 1 GOES HERE

TEXT 2 GOES HERE

TEXT 3 GOES HERE

I want it to be like this;

TEXT 1 GOES HERE
TEXT 2 GOES HERE
TEXT 3 GOES HERE

I'm trying this code;

    $news_setting = str_replace('

','
',$news_settings);
    $news_array = explode("
",$news_setting);
    foreach($news_array AS $news)
    {
        $news_bit .= '<div class="news_bit">'.$news.'</div>';
    }

But unfortunately its not removing any extra line break. Please help!

Try this:

    $news_setting = preg_replace("/(^[
]*|[
]+)[\s\t]*[
]+/", "
", $news_settings);
    $news_array = explode("
",$news_setting);
    foreach($news_array AS $news)
    {
        $news_bit .= '<div class="news_bit">'.$news.'</div>';
    }
