@ Nigel Ren , I have to do as your tell me...with json.. , I have to try without Json but because I am very new with PHP , I don't know to do it....

Maybe the title of my question , php file_put_contents without bytes written is not the best ....because it is not the responsibility by my bytes number , rather the serialize Function ..... . Maybe an best title would to be , PHP - How display return Value without bytes number and without Json .

Because I have an array in my Code

$data = array("name" => $this->Name, "email" => $this->Email, "message" => $this->Message, "datetime" => $datetime);

should to utilize the Function serialize , therefore I receive the output with number of bytes .

Serialize Function

A PHP array or object or other complex data structure cannot be transported or stored or otherwise used outside of a running PHP script. If you want to persist such a complex data structure beyond a single run of a script, you need to serialize it. That just means to put the structure into a "lower common denominator" that can be handled by things other than PHP, like databases, text files, sockets. The standard PHP function serialize is just a format to express such a thing, it serializes a data structure into a string representation that's unique to PHP and can be reversed into a PHP object using unserialize. There are many other formats though, like JSON or XML.

From here (First Answer..)

So , because I will not receive my return Values together with Number of bytes and I don't know to do only with PHP, I utilize Json .In my Code , I have only to change the else statement , rest from the code stay identical .

else 
{

      $file = "test.txt"; 

      $datetime = date('m/d/Y h:i:s a', time());
      $data = array("name" => $this->Name, "email" => $this->Email, "message" => $this->Message, "datetime" => $datetime);


      $data = json_encode($data);
      file_put_contents($file, $data . "\n", FILE_APPEND|LOCK_EX);


      $messages = file($file);

      foreach ($messages as $value) {
           $data = json_decode($value, true);


                  echo "<br>"

                             . "<b>From: </b>" . htmlspecialchars( $data["name"])
                             . "<b> at: </b>" . htmlspecialchars( $data["datetime"])
                             . "<br><br>" . htmlspecialchars( $data["email"])                                     
                             . "<br><br>" . htmlspecialchars( $data["message"])
                             . "<br><hr>";

      }

}

und now my output from my File test.txt

{"name":"aaaa","email":"aaa@gmx.de","message":"mmmmmmmmmmmmmmmmmmmmmmmmmmm","datetime":"11/12/2018 02:49:46 pm"}
