What the script does

1    $filelocation = "mytext.txt";
2    if (!file_exists($filelocation)) {
3    echo "Couldn't find datafile, please contact administrator!";
4    }
5    else {
6    $newfile = fopen($filelocation,"r");
7    $content = fread($newfile, filesize($filelocation));
8    fclose($newfile);
9    }
10    $content = stripslashes($content);
11    $content = htmlentities($content);
12    $content = nl2br($content);
13    echo $content;

Line 1 defines the name of the text file, in line 2-4 the script checks if the file is there and displays a message, when there is no datafile.

If there is a datafile, then the lines 6-8 read it's content into the variable $content.

Lines 10-12 manipulate the content, the backlslashes php adds to quotationsmarks are removed, umlauts and special characters are replaced by their html equivalent and every linebreak becomes a <br />.

Now, we're halfway there, we only need to add the tool that changes the content of the textfile.
