Indefinite variable PHP_SELF

Navigation

I'm doing a small example to identify when a page is reloaded for the second time, use php v5.7.14

PHP: 

<?php

if ($_SERVER['REQUEST_METHOD'] == 'POST') 
{
    echo "primera vez";
}
else
{
    echo "mas de primera";
}?>

HTML: 

<html>
<head>
    <meta charset="UTF-8">
    <title>ReCaptcha Demo</title>
</head>
<body>

    <form class="register" action="<?php echo $PHP_SELF;?>" method="post">
        <input type="text" name="Nombre" required="required" />
    </form>

</body>

Throw the following ERROR:

The variable is misspelled should be something like this: 

<form name="form1" method="post" action="<?php echo $_SERVER['PHP_SELF']; ?>" >
