Create index.php file and put code inside of index.php file

In this tutorial, we will learn how to data store inside of CSV file using PHP. CSV is a comma-separated value file in which it stores tabular data in plain text format. It stores one record in one line and for the second record, it will store in the second line.

<?php
//index.php

$error = '';
$name = '';
$email = '';
$subject = '';
$mobile = '';
$message = '';

function clean_text($string)
{
 $string = trim($string);
 $string = stripslashes($string);
 $string = htmlspecialchars($string);
 return $string;
}

if(isset($_POST["submit"]))
{
 if(empty($_POST["name"]))
 {
  $error .= '<p><label class="text-danger">Please Enter your Name</label></p>';
 }
 else
 {
  $name = clean_text($_POST["name"]);
  if(!preg_match("/^[a-zA-Z ]*$/",$name))
  {
   $error .= '<p><label class="text-danger">Only letters and white space allowed</label></p>';
  }
 }
 if(empty($_POST["email"]))
 {
  $error .= '<p><label class="text-danger">Please Enter your Email</label></p>';
 }
 else
 {
  $email = clean_text($_POST["email"]);
  if(!filter_var($email, FILTER_VALIDATE_EMAIL))
  {
   $error .= '<p><label class="text-danger">Invalid email format</label></p>';
  }
 }
 if(empty($_POST["subject"]))
 {
  $error .= '<p><label class="text-danger">Subject is required</label></p>';
 }
 else
 {
  $subject = clean_text($_POST["subject"]);
 }

if(empty($_POST["mobile"]))
 {
  $error .= '<p><label class="text-danger">Mobile is required</label></p>';
 }
 else
 {
  $mobile = clean_text($_POST["mobile"]);
 }
 
 if(empty($_POST["message"]))
 {
  $error .= '<p><label class="text-danger">Message is required</label></p>';
 }
 else
 {
  $message = clean_text($_POST["message"]);
 }

 if($error == '')
 {
  $file_open = fopen("contact_data.csv", "a");
  $no_rows = count(file("contact_data.csv"));
  if($no_rows > 1)
  {
   $no_rows = ($no_rows - 1) + 1;
  }
  $form_data = array(
   'sr_no'  => $no_rows,
   'name'  => $name,
   'email'  => $email,
   'subject' => $subject,
   'mobile' => $mobile,
   'message' => $message
  );
  fputcsv($file_open, $form_data);
  $error = '<label class="text-success">Thank you for contacting us</label>';
  $name = '';
  $email = '';
  $subject = '';
  $mobile = '';
  $message = '';
 }
}
