Answer 1

the following function will find all the lines that match your string, and it will echo the line number, as $i

    function getLine($string)
    {

    $file = fopen("fle.txt", "r") or exit("Unable to open file!");
    //Output a line of the file until the end is reached
    $i = 0;
    while(!feof($file))
      {
       $i++;
       $line = fgets($file);
       $pos = strpos($line, $string);
       if( $pos !== false )echo $i.'<br/>';
      }
    fclose($file);

    }

by the way, don’t escape characters, don’t use \ within the string parameter, as you did in yur code
