working with files

hi, i have problem with writing a reading to file i want to write emails in files. like this email1@email1.com email2@email2.com email3@email3.com etc...... this is how I write to the file $handle = fopen($filename, "a"); fwrite($handle,"$email\n",128); fclose($handle); ok it writes everything just fine but now i want to read the file line by line and print line by line. this is how i do it. <?php $handle = fopen ($filename, "r"); do { $data = fread($handle, 128); if (strlen($data) == 0) { break; } print ("$data<br>"); } while (true); fclose($handle); ?> the problem i get then is everything is printed in one line. any help is appreciated.
