Hello Programmers, in this post I am going to show you a very essential task that can be easily done with Core PHP and HTML form.
Sometimes it happens that we need to store some data in a local storage file rather than making it complex using the database.
Yes, it’s a fact that in many cases we don’t want to store our text data in database always.
Here I am giving you an example:
Suppose you have an HTML form and you want to store the data submitted by the user in a text file so that you can easily access it later from that file.
PHP Program to store HTML Form data in a .txt File
Below I have provided the PHPcode to store the form data in a text file. Just took a glance at this code.
For easy understanding, after the code, I have provided the explanation and how to use this code step by step.
<?php if(isset($_POST['textdata'])){$data=$_POST['textdata'];$fp = fopen('data.txt', 'a');fwrite($fp, $data);fclose($fp);}?>Here textdata is the name of our HTML form field from the post data that is provided below.
data.txt is a file that we have to create for storing our form submission data in it.
$datais a PHP variable to store the form field data entered by the user.
Now below is given the HTML part for creating the form:
<!DOCTYPE html><html><head> <title>Store form data in .txt file</title></head><body> <form method="post"> Enter Your Text Here:<br> <input type="text" name="textdata"><br> <input type="submit" name="submit"> </form></body></html>
From the above form our data be submitted.
Now I think you have understood the thing.

How to Count The Sub String from a .txt file using PHP
look at the below code. It will also work fine
<?php $data = $_POST['textdata'];$fp = fopen('data.txt', 'a');fwrite($fp, $data);fclose($fp);This will work fine. But in some servers, it might show an error like this
“Undefined index: ”
in order to prevent the error warning we useisset()
so it’s safe to use this before $_POST[‘value’];
something like this one
if(isset($_POST['value'])) { //////your code }
