Write in a .txt File from a form in PHP

I saw this question and I wanted to ask a question in the comment but didn't have enough reputation. So I'm asking the question here.

I have a form in HTML:

<form action="myprocessingscript.php" method="POST">
Name : <input name="field1" type="text" />
Email : <input name="field2" type="text" />
<input type="submit" name="submit" value="Save Data">

And a processing script in php, myprocessingscript.php :

if (isset($_POST['field1']) && isset($_POST['field2'])) {
  $data = 'comments.txt' . $_POST['field1'] . ' ' . $_POST['field2'] . "\n";
  $ret = file_put_contents('comments.txt', $data);

  if ($ret === false) {
    die('There was an error Sending The Comment');
  } 

  else {
    echo "The Comment Has Been Sent Succesfully !";
  }
} 

else {
  die('Fill in The Form Please !');
}

if (isset($_POST['field1']) && isset($_POST['field2'])) {
  $data = 'comments.txt' . $_POST['field1'] . ' ' . $_POST['field2'] . "\n";
  $ret = file_put_contents('comments.txt', $data);

  if ($ret === false) {
    die('There was an error Sending The Comment');
  } 

  else {
    echo "The Comment Has Been Sent Succesfully !";
  }
} 

else {
  die('no post data to process');
}

When I write something in the form to a text file (comments.txt) the previous text is deleted - what should I do?

You just need to add the 'append' flag to file_put_contents() :

file_put_contents('comments.txt', $data, FILE_APPEND);

See : https://www.php.net/manual/en/function.file-put-contents.php
