Adding results of form to .txt file

Anon

I'm completely inexperienced at PHP but I would like to try making a PHP script that allows me to fill out a form (sort of an admin form) which would save the result to a .txt file.
I would then include the .txt file into a page on my site.

Why not use MySQL to do it in databases?

Because that sounds far more complicated than just saving variables to a text file.
I'm ~really~ new to programming, and decided my first code would be PHP.
What I'd like to do is fill in a form.
There'd be three fields

input type=text name=example1
input type=text name=example2
input type=text name=example3
submit to example.php

Each name variable would be written to a file.

This is <?php echo $example1;?>
This is <?php echo $example2;?>
This is <?php echo $example3?>

I know this from the php.net tutorial, but it's as far as I've gotten.
I know I need to use fwrite and fopen, but exactly how I use those commands is beyond me.

As soon as you get serious in this sort of thing you'll be wanting to use a database instead of a text file, trust me :-)

Check out www.php.net/fopen

$filename="mytextfile.txt";

//Open a connection to the file, "w" indicates we wish to write to it:
$file=fopen($filename,"w");

//If we couldn't open the file for some reason we can't write to it.
//(Production code would handle this more gracefully)
if(!$file)
die("Urk, failure to open $filename");

//Okay, we have our file open and reading for writing to.

//Don't forget the newlines!
fwrite($file, "This is $example1\n");
fwrite($file, "This is $example2\n");
fwrite($file, "This is $example3\n");

//Done
fclose($file);

Would I save that code as blah.php and point a form to it?
Or, do I point the form to itself?

This is the form:

<HEAD><TITLE>I am....</TITLE>
<META http-equiv=content-type content="text/html; charset=iso-8859-1">
<META http-equiv=pragma content=no-cache>
<META content="Chris Harker" name=author>
<META content="2001 Chris Harker" name=copyright>
<META content="Max: Considered Harmful"
name=description>
<META
content="blog, journal, web, design, styleswitcher.js, green, uk, english, diary, free, fonts, winamp" name=keywords>
<META content=all name=robots>
<META content="MSHTML 6.00.2712.300" name=GENERATOR>
<LINK href="http://max.krazeelove.com/format/blueboy.css" type=text/css rel=stylesheet></HEAD>
<FORM action="updateit.php" method=post>
I am listening to:<br>
<input type=text name=music><br>
I am currently:<br>
<input type=text name=status><br>
I should be:<br>
<input type=text name=should><br>
I love:<br>
<input type=text name=love><br>
<input type=submit>
</form>
</body>

this is updateit.php

<?php

$filename="http://max.krazeelove.com/update.txt";

//Open a connection to the file, "w" indicates we wish to write to it:
$file=fopen($filename,"w");

//If we couldn't open the file for some reason we can't write to it.
//(Production code would handle this more gracefully)
if(!$file)
die("Urk, failure to open $filename");

//Okay, we have our file open and reading for writing to.

//Don't forget the newlines!
fwrite($file, "I am listening to $music\n");
fwrite($file, "I am currently $status\n");
fwrite($file, "I should be $should\n");
fwrite($file, "I love $love\n");

//Done
fclose($file);
?>

what am I doing wrong?

Simple enough; your "file" is an (inherently read-only) HTTP connection.
