I am having a sort of an issue with something.

I am writing a script where, the user inputs some information in a form, and based on that form, a new file is created.

The file which is created will actually become a webpage of .php type.

The problem I am having is in creating that webpage, I can't seem to make it so that the form posted data is used.

For instance, where I write $file to the page, it writes $file rather than the value of that variable.

I have tested to make sure that the variable itself is accurate by echoing $file as well.
Here is the code that I am using.

I am assuming that it has something to do with the fact that I have this string in single quotes, however, this is the only way that I could do it without having to type a bunch of escapes. Can someone please tell me if there is a way to do this same thing without the need for all the escapes? Or if there is something else wrong with the code?

<?
$file = $_POST[file];
$newstring = '<!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=utf-8" />
<title>Untitled Document</title>
</head>
<body>
<form action="newfile.php" method="post" name="new">
<? echo $file; ?> <input name="file" type="text" size="30" maxlength="60" /><input name="" type="submit" value="CREATE FILE" />
</form>
</body>
</html>';
$newfile = fopen($file, "w+") or die ("could not create file.");
fclose($newfile);
$myfile = @fopen($file, "w+") or die ("could not open file.");
@fwrite($myfile, $newstring) or die ("could not write to file");
fclose($myfile);
$msg = "<p>File created <a href='$file'>$file</a> and it has stuff in it</p>";
?>

Thanks

There. This should work! You were using php tags in a variable which was already in a php script.

Thanks to both of you for your replys.
The second one worked (obviously).
I'm not sure what you mean, Naju, by making the inverted commas in proper order.

I am assuming that you are talking about escapes, but, that's sort of the point, I am doing this without using escapes.

I will test out your suggestion just to see what it does, but, I have a feeling that all it will do is pring $file, rather than the value of that variable.

Thanks.
