How To Keep textarea content

I have a code :

<?php
    if(isset($_POST['data'])) {
        $myFile = "/var/www/vhosts/domain/subdomain/index.php";
        $fh = fopen($myFile, 'w');
        fwrite($fh, $_POST['data']);
    } else {
        $myFile = "/var/www/vhosts/domain/subdomain/index.php";
        $fh = fopen($myFile, 'r');
        $theData = fread($fh, filesize($myFile));
    }
    fclose($fh);
?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml">
    <head>
        <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />
        <title>Untitled Document</title>
    </head>
    <body>
        <form name="test" method="post" action="">
            <textarea name="data"><?php echo $theData; ?></textarea>
            <input type="submit" name="submit" value="Update File" />
        </form>
    </body>
</html>

When I click submit content of the textarea is lost. How can I solve this?

If you want to keep the content of the textarea even after the form submission use the code:

<?php
$theData = '';
if(isset($_POST['data'])) {

// here is assigning the content to be displayed on form submit
$theData = $_POST['data'];
$myFile = "/var/www/vhosts/domain/subdomain/index.php";
$fh = fopen($myFile, 'w');
fwrite($fh, $_POST['data']);
} else {
$myFile = "/var/www/vhosts/domain/subdomain/index.php";
$fh = fopen($myFile, 'r');
$theData = fread($fh, filesize($myFile));
}
fclose($fh);
?>

</head>

<body>
<form name="test" method="post" action="">
<textarea name="data"><?php echo $theData; ?></textarea>
<input type="submit" name="submit" value="Update File" />
</form>
</body>
</html>

You need to add $theData variable in submit also because after submitting you again need to read the data in order to show them.

<?php
if(isset($_POST['data'])) {
    $myFile = "/var/www/vhosts/domain/subdomain/index.php";

    //here I changed the permission with read/write mode.
    $fh = fopen($myFile, 'rw');
    fwrite($fh, $_POST['data']);
    //this line to be added for getting the data after inserting.
    $theData = fread($fh, filesize($myFile));
} else {
    $myFile = "/var/www/vhosts/domain/subdomain/index.php";
    $fh = fopen($myFile, 'r');
    $theData = fread($fh, filesize($myFile));
}
fclose($fh);
?>

And put htmlspecialchars while echo that variable

<?php echo htmlspecialchars($theData); ?>

Make a little change in your code:

$fh = fopen($myFile, 'rb'); // Notice b here
$theData = fread($fh, filesize($myFile));
