HTML

<HTML><BODY> 
<TABLE> 
<FORM METHOD='POST' ACTION=''> 
<TR> 
<TD>Give your file a name, <BR/>remember extension (.txt)</TD> 
<TD><INPUT TYPE='text' NAME='filename'></TD> 
</TR> 
<TR> 
<TD>Click here to create file: </TD> 
<TD><INPUT TYPE='submit' NAME='doit' VALUE='Create textfile'></TD> 
</TR></FORM> 
</TABLE> 
</BODY></HTML>

PHP

As you see on the first tab, using 'w' or 'w+' will create the file is if doesn not exist.
That is what we use here.

<?php
    if (isset($_POST['doit']))  { 
    $filename = $_POST['filename']; 
    $stien = getcwd(); 
    $file = fopen($stien . "/" . $filename, 'w'); 
    fclose();	 
    echo "Finished"; exit(); 
}
?>
