In what way is it "not working"?

What do you want to happen so you can say it is working?

When posting, bear in mind we are not psychic and cannot see your screen and the data values you are seeing.

I would recommend not to use this low level functions. At best you take a database with ACID compatibility, if you want to get a quick slim start, use SQLite, it's mostly build-in into PHP. But at least you can use json_encode(), file_put_contents(), file_get_contents() and json_decode() for your task, so you have clean and readable interface without thinking too much.

On the other hand, file handling and format manipulation is a valuable lesson.

But as already said, you have to tell us what problem you encountered in detail.

<?php

if(isset($_POST['textdata']))

$fp = fopen('data.txt', 'a');
fwrite($fp, $data);

This suggests a very bad database design. Joining multiple values and placing them all into one record is not the way to store data. This should really be done by making multiple related records in a separate table, linked to the main record for the user/item/primary key so that you can then easily do queries for these data values. Your current design/approach prevents this from being easily done.

Pity. If you had read on you'd have seen he is writing to a text file.

Barand · November 21, 2019

if I were you I'd use a newline (\n) to separate the data instead of "@@@".

if(isset($_POST['textdata']))
{
    file_put_contents('data.txt', $_POST['textdata']."\n", FILE_APPEND);
}

Then, if you data.txt file contains, say

TESTA
TESTB
TESTC
TESTD

... you can read it back and separate the items into an array using file();

$data = file('data.txt');

giving

$data = Array
(
    [0] => TESTA

    [1] => TESTB

    [2] => TESTC

    [3] => TESTD
)

Ok im using the Xampp. Program to startup webserver ill see how to turn on error reporting on. I just started using it to test my website before i put it on my paid web hosting .www example:mydomain.com/home1.php thanks

This xampp is the best

It installs everything php perl so it works correctly

Sometimes i forget how to edit php.ini file

You know configuration

With xampp it makes it all work all you do is start up the webserver

5 stars xampp.

You can turn on error reporting in your script by putting this at the top of the page

error_reporting(E_ALL);

You would find Laragon to be even better. (Coming from a former Xampp user)

Can it be installed along with xampp on the same machine or would it conflict.

Thanks.

benanamen · November 23, 2019

Yes but you don't want to run both at the same time. If you really wanted to, you would need to change the Apache port on one of them as they both use port 80
