Easily Update Dynamic Text File

[DANSSWARE]

I have a flash site powered by dynamic text files. These call formatting, etc. I need to create some sort of online form that can post additions to the file in the proper format of the text file... How can I go about this?

You are reading variables (text) from text file, and you want to write to same file at the end of file?

Yea.. Flash draw the variable from the text file and I want to append to the top of the text file, within the one variable.

Thanks!

Not knowing the construction of your txt file with dynamic data, presuming that text file is containing multiple variables, in wich case first variable is Var1=Something, and the others are &VarZ=Else, try this PHP function.<?php
//path to the file
$path = "Variables.txt";
//chmod($path, 0777); - You may need this to write on disk!

//request new variables
$append = $_REQUEST['Data'];
$appenddata = "$append\r\n&";

//Just a precaution in case of empty Data string
if (!empty($append)) {

//reading
$r = fopen($path,"r");
$read = fread($r, filesize($path));
fclose ($r);

//writing
$w = fopen($path,"w");
fwrite($w, "$appenddata$read");
fclose ($w);
}
