Remove multiple lines

I have a webpage that has many linefeeds.

 

I want to replace all lines feeds greater than 2 with only one linefeed.

 

Please can anyone help me with that ?.

 

Thnx in advance.

^{(*not tested code)}

$Lines=explode("\n", $input);
$output = "";
foreach($Lines as $Line){
  if(trim($Line) > ''){ 
     $output .= $Line."<br>";
  }
}
echo $output;

hope that helps

Well it is removing all the lines.

 

I want the output as above.

 

Thanx for your effort.

$Lines=explode("\n", $input);
$output = "";
$last = "";
foreach($Lines as $Line){
     if($last != "<br>"){
          $output .= trim($Line)."<br>";
          $last = trim($Line);
     }
}
echo $output;

yeah, my bad... try that

hmm, was pondering and this may also work...

$output = str_replace("\n", "\n " $input); //add spaces after all \n's
$output = str_replace("  ", " " $output); //replace double spacing with single
$output = str_replace("\n \n ", "\n ", $output); //replace all occurrences of two \n's with single
