This is how you do it (as for nico_swd’s post)

1. Open the file
2. Click CTRL + F
3. Select “Current document” in “Find in” (You can also select the folder if you have multiple files)
4. Search in “Source code”
5. Tick “Use regular expression”
6. Type “[\r\n]{2,}” (without quotes) in “Find”
7. Type “\n” (without quotes) in “Replace”
8. Press “Replace All”

HTML Form:

<form action=”test_search.php” method=”post” name=”d”>
<input name=”send” type=”hidden” value=”1″ />
<input name=”term” type=”text” />
<input name=”submit” type=”submit” value=”submit” />
</form>

PHP Code:

<?php
//this fucntion is used to get the tile tag of the page
function get_title($a,$b,$c){
$y = explode($b,$a);
$x = explode($c,$y[1]);
return $x[0];
}

//if form is submited do the following

if(isset($_POST['send'])){
if ($handle = opendir(‘/path to your directory/’)) { //example path  /home/site-user-name/public_html/my-folder/
 // lets loop over the directory.
 $i=0;
 while (false !== ($file = readdir($handle))) {
     if ($file != “.” && $file != “..”) {
   $page= ‘myfolder/’.$file;
   $page= file ($page);
   $numtlines = count ($page); //Number of lines in the file
   
   $line = 0;
   while ($line < $numtlines) {
    if(stristr ($page[$line], ”.$_POST['term'].”)){ //found a match

     //let’s get the page title
     echo ‘<br><a href=”http://www.url-to-your-file/’.$file.’”>”‘.get_title(file_get_contents(‘http://www.url-to-your-file/’.$file), “<title>”, “</title”).’</a><br>’;
     $metatagarray = get_meta_tags(‘http://www.url-to-your-file/’.$file);
     echo $description = $metatagarray[ "description"];
     $line = $numtlines;
    }
    $line++;
   }
     }
 $i++;
 }
closedir($handle);
}
}
?>
