file - PHP Escaping Quotes Automatically When Using fwrite()

PHP is automatically escaping my quotes before writing to a file using fwrite. I am trying to make a test code page. Here is the code I have:

<?php
if ($_GET['test'] == 'true') {
$code = $_POST['code'];
$file = fopen('testcode.inc.php', 'w+');
fwrite($file, $code);
fclose($file);
require_once('testcode.inc.php');
}
else {
echo "
<form method='post' action='testcode.php?test=true'>
<textarea name='code' id='code'></textarea><br><br>
<button type='submit'>Test!</button><br>
</form>
";
}
?>

When I enter the following into my form:

<?php
echo 'test';
?>

It gets saved in the file as:

<?php
echo 'test';
?>

Why is php automatically escaping my quotes?

It's not fwrite, its $_POST

With these knowledge please find you answer here:

So what you have to do is just small fix:

if (get_magic_quotes_gpc()) {
  $code = stripslashes($_POST['code']);
}else{
  $code = $_POST['code'];
}
