HELP!: FOPEN/creating a PHP FILE; How do i do this? Details inside.

So here's a rundown of what i need to get working


When a user registers on my site, i need a file to be instantly created SPECIFICALLY FOR THAT MEMBER.

This PHP file needs to be made for the member

<?php
// Create a new image instance
$im = imagecreatetruecolor(1, 1);

// Make the background white
imagefilledrectangle($im, 0, 0, 1, 1, 0xFFFFFF);

// Draw a text string on the image
imagestring($im, 3, 40, 20, '', 0xFFBA00);

// Output the image to browser
header('Content-type: image/gif');

  $time = time();
$myFile = "/home/webmast/public_html/MYWEBSITE.com/[b]$username.txt[/b]";
$fh = fopen($myFile, 'w+b') or die("can't open file");
$stringData = "lots of stuff here\n";
fwrite($fh, $stringData); 


imagegif($im);
imagedestroy($im);
?>

Code (markup):

I already have the $username variable set. All i need to do is CREATE A PHP FILE with the ABOVE CONTENT per user, just use the $username variable for the .php FILE NAME with the above content, and have the NEWLY CREATED FILE (above content) display THEIR USERNAME under $username.txt )

Thanks so much to whoever helps me out with this Sorry if i made it confusing.

 

In simpler terms (now that i think about it); THE HELP I NEED FROM YOU DP'ERS:


The code to CREATE A PHP file named $username.php - username is already defined on my side

That php file will have

<?php
// Create a new image instance
$im = imagecreatetruecolor(1, 1);

// Make the background white
imagefilledrectangle($im, 0, 0, 1, 1, 0xFFFFFF);

// Draw a text string on the image
imagestring($im, 3, 40, 20, '', 0xFFBA00);

// Output the image to browser
header('Content-type: image/gif');

  $time = time();
$myFile = "/home/webmast/public_html/MYWEBSITE.com/[B]$username.txt[/B]";
$fh = fopen($myFile, 'w+b') or die("can't open file");
$stringData = "lots of stuff here\n";
fwrite($fh, $stringData); 


imagegif($im);
imagedestroy($im);
?>

Code (markup):

With the above created file, it will ALSO have the specific $username in the above bolded part ($username) in the code for the newly created php.


So basically it needs to create the php file named username.php, and write that username.php accordingly with the $username.txt part in the code

 

Why on earth would you want to do this? It will scale poorly and provides no advantage that I can think of.

 

instead of creating the same file for each user just use the same file with enabling url-rewriting in htaccess file.
for examle when opening $username.php actually it will open phpfile.php?user=$username

example code:
RewriteRule ^(.*)\.php$ phpfile.php?user=$1 [L]
