PHP - Dynamically Create Text File

Submitted by razormist on Saturday, August 31, 2019 - 20:07.

In this tutorial we will create a Dynamically Create Text File using PHP. This code can create a text file with content dynamically when user submit the form inputs. The code use PHP POST to launch a specific method that create a text using these special php functions fopen() to open an existing file and if not exist it will create a new file, fwrite() insert some content in the text file, and lastly fclose() safely close the connection between the opened file. This is a user-friendly kind of program feel free to modify it. We will be using PHP as a scripting language and interpreter that is used primarily on any webserver including xamp, wamp, etc. It is being use to any famous websites and it has a modern technology that can easily be use by the next generation.

Getting Started:

First you have to download & install XAMPP or any local server that run PHP scripts. Here's the link for XAMPP server https://www.apachefriends.org/index.html. And, this is the link for the bootstrap that i used for the layout design https://getbootstrap.com/.

Creating The Interface

This is where we will create a simple form for our application. To create the forms simply copy and write it into your text editor, then save it as index.php.

<!DOCTYPE html>
<html lang="en">
        <head>
                <meta charset="UTF-8" name="viewport" content="width=device-width, initial-scale=1"/>
                <link rel="stylesheet" type="text/css" href="css/bootstrap.css"/>
        </head>
<body>
        <nav class="navbar navbar-default">
                <div class="container-fluid">
                        <a class="navbar-brand" href="https://sourcecodester.com">Sourcecodester</a>
                </div>
        </nav>
        <div class="col-md-3"></div>
        <div class="col-md-6 well">
                <h3 class="text-primary">PHP - Dynamically Create Text File</h3>
                <hr style="border-top:1px dottec #ccc;"/>
                <div class="col-md-4">
                        <div class="form-inline">
                                <form method="POST" action="create_file.php">
                                        <label style="font-size:18px;">Filename:</label>
                                        <input type="text" name="filename" class="form-control" required="required"/>
                                        <br /><br />
                                        <label>Enter a Text</label>
                                        <textarea name="content" style="width:100%; height:100px; resize:none;"></textarea>
                                        <br /><br />
                                        <center><button class="btn btn-primary" name="create">Create File</button></center>
                                </form>
                        </div>
                </div>
                <div class="col-md-8">
                        <table class="table table-bordered">
                                <thead class="alert-info">
                                        <tr>
                                                <th>File Name</th>
                                        </tr>
                                </thead>
                                <tbody>
                                        <?php
                                                $full_path = "files";
                                                
                                                $dir = opendir($full_path);
                                
                                                while(($file = readdir($dir)) !== FALSE){
                                                        if($file == "." || $file == "..")
                                                                
                                                        continue;
                                                ?>
                                                        <tr>
                                                                <td><?php echo $file?></td>
                                                        </tr>   
                                        <?php
                                                
                                                }
                                                
                                                closedir($dir);
                                        ?>
                                
                                </tbody>
                        </table>
                </div>
        </div>
        
        
</body>
</html>

Creating the Main Function

This code contains the main function of the application. This code will create a text file when the button is clicked. To make this just copy and write these block of codes below inside the text editor, then save it as string.php

<?php
        if(ISSET($_POST['create'])){
                $content = $_POST['content'];
                $file_name = $_POST['filename'];
                $path = "files";
                $file = fopen($path."/".$file_name.".txt", 'w');
                fwrite($file, $content);
                fclose($file);
                header("location:index.php");
        }
?>
