View edit save text file database using PHP

. We are using fopen to open the file and fputs to save the file using PHP. There will be a form where you can edit the file and submit the changes.

//your file name here
$fn = "My_File.txt";
if (isset($_POST['content']))
{
    $content = stripslashes($_POST['content']);
    $fp = fopen($fn,"w") or die ("Error opening file in write mode!");
    fputs($fp,$content);
    fclose($fp) or die ("Error closing file!");
    header('Location: ANY_FILE_TO_BE_REDIRECTED.php');
}
?>
<form action="<?php echo $_SERVER&#91;"PHP_SELF"&#93; ?>" method="post">
    <textarea rows="15" cols="80" name="content">< ?php readfile($fn); ?></textarea>
	<br />
    <input type="submit" value="Save"/> 
</form>
