The writefile.html file (online form):
<html> <head><title>Writing to a file</title></head> <body> <form method="post" action="writefile.php"> Input the html/txt text to write here:<br /> <textarea rows="10" cols="50" name="html"></textarea> <br /> <input type="submit" value="Write" /> </form> </body> </html>

The writefile.php file:
<html> <head><title>Writing to a file</title></head> <body> <?php //We retrieve the text from the online form if(!isset($_POST['html'])) { echo 'Nothing to write, please go back and enter something!'; } else { //escape the blank spaces around the text $_POST['html']= trim($_POST['html']); $pathandfile='dir/file.htm'; /*open the file and store the address into the variable $handle - 'w' means: open for writing only, create it if not existing (http://www.php.net/manual/en/function.fopen.php)*/ if (!$handle = fopen($pathandfile, 'w')) { echo "Cannot open file ($pathandfile)"; exit; } //Write the content to the opened file. if(fwrite($handle,$_POST['html']) === FALSE) { echo "Cannot write to file ($pathandfile)"; echo '</body></html>'; exit; } echo 'Success, wrote the content to the file: <a href="'.$pathandfile.'">Check it here</a>'; //we close the file fclose($handle); } ?> </body> </html>

From the page http://www.php.net...fopen.php you can learn about the following features:

A list of possible modes for fopen() using mode:

mode	Description
'r'	Open for reading only; place the file pointer at the beginning of the file.
'r+'	Open for reading and writing; place the file pointer at the beginning of the file.
'w'	Open for writing only; place the file pointer at the beginning of the file and truncate the file to zero length. If the file does not exist, attempt to create it.
'w+'	Open for reading and writing; place the file pointer at the beginning of the file and truncate the file to zero length. If the file does not exist, attempt to create it.
'a'	Open for writing only; place the file pointer at the end of the file. If the file does not exist, attempt to create it.
'a+'	Open for reading and writing; place the file pointer at the end of the file. If the file does not exist, attempt to create it.
'x'	Create and open for writing only; place the file pointer at the beginning of the file. If the file already exists, the fopen() call will fail by returning FALSE and generating an error of level E_WARNING. If the file does not exist, attempt to create it. This is equivalent to specifying O_EXCL\|O_CREAT flags for the underlying open(2) system call. This option is supported in PHP 4.3.2 and later, and only works for local files.
