how to add data to a specific line of a flatfile

[Meridian]

Hi there,

I'm making a news updater that has to be written to a flatfile since flash doesn't read mysql (or at least I don't think it does)

The thing is I have my code working like a champ but it's working backwards.

this

<?php
@extract($_POST);
if(is_writable('news.txt'))
{
$fp = fopen('news.txt','at');

$content = "$start\n\n$dateformat1$date$dateformat2$headerformat1$header$headerformat2$body";

fwrite($fp,stripslashes($content));
fclose($fp);
echo'your changes have been made';
}
else
{
echo'File is not writable';
}
?>

I know "a" adds text to then end of the file and "w" adds it to the begining of the file. But what I need is to add text to the 4th line of the file and move all existing information down to the next line.

I'm a beginner and this code uptop is actually my first php I've ever written so please be gentle.. 🙂

well, flash can't read mysql, but flash CAN read php which can read mysql

anyways, use the line() function. this places each line of a file into elements of an array. write the first three lines from the array, then write the line u need, then continute from the array. try this and tell me if it works.

Hmm I searched php.net for documentation on line() and nothing came up... are you sure that's the function?

my bad, it's file()
