PHP Refresh does not post but output data solution

PHP does not post but output data after refresh
My PHP code is as follows:



<title>Network Message Board</title>


Error_reporting (E_all & ~e_notice);
function Write_message ($file _name, $message)
{
$fp = fopen ($file _name, "a"); Open file in Append mode
if (Flock ($FP, LOCK_EX))
{
Fwrite ($fp, $message);
Flock ($FP, lock_un);
}
Else
{
echo "Cannot lock file
";
}
Fclose ($FP); Close File Resource
}

Customizing a function to traverse the read file
function Read_message ($file _name)
{
$fp = fopen ($file _name, "R"); Open a file in read-only mode
Flock ($FP, lock_sh);
$buffer = "";

while (!feof ($FP))
{
$buffer. = Fread ($fp, 1024);
}

$data = Explode ("<|>", $buffer);
Unset ($data [Count ($data)-1]);
foreach ($data as $line)
{
$arr = Explode ("| |", $line);
List ($user _name, $title, $message) = $arr;
if ($user _name! = "" && $title! = "" && $message! = "")
{
echo $user _name. ' Say ';
echo "". $title. ' ';
echo $message. " ";
}
}

Flock ($FP, lock_un);
Fclose ($FP);
}
