PHP - Dynamically Create Text File

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

And, this is the link for the bootstrap that i used for the layout design

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.

  1. <!DOCTYPE html>
  2. <html lang="en">
  3. <head>
  4. <meta charset="UTF-8" name="viewport" content="width=device-width, initial-scale=1"/>
  5. <link rel="stylesheet" type="text/css" href="css/bootstrap.css"/>
  6. </head>
  7. <body>
  8. <nav class="navbar navbar-default">
  9. <div class="container-fluid">
  10. <a class="navbar-brand" href="">Sourcecodester</a>
  11. </div>
  12. </nav>
  13. <div class="col-md-3"></div>
  14. <div class="col-md-6 well">
  15. <h3 class="text-primary">PHP - Dynamically Create Text File</h3>
  16. <hr style="border-top:1px dottec #ccc;"/>
  17. <div class="col-md-4">
  18. <div class="form-inline">
  19. <form method="POST" action="create_file.php">
  20. <label style="font-size:18px;">Filename:</label>
  21. <input type="text" name="filename" class="form-control" required="required"/>
  22. <br /><br />
  23. <label>Enter a Text</label>
  24. <textarea name="content" style="width:100%; height:100px; resize:none;"></textarea>
  25. <br /><br />
  26. <center><button class="btn btn-primary" name="create">Create File</button></center>
  27. </form>
  28. </div>
  29. </div>
  30. <div class="col-md-8">
  31. <table class="table table-bordered">
  32. <thead class="alert-info">
  33. <tr>
  34. <th>File Name</th>
  35. </tr>
  36. </thead>
  37. <tbody>
  38. <?php
  39. $full_path = "files";
  41. $dir = opendir($full_path);
  43. while(($file = readdir($dir)) !== FALSE){
  44. if($file == "." || $file == "..")
  46. continue;
  47. ?>
  48. <tr>
  49. <td><?php echo $file?></td>
  50. </tr>
  51. <?php
  53. }
  55. closedir($dir);
  56. ?>
  58. </tbody>
  59. </table>
  60. </div>
  61. </div>
  64. </body>
  65. </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

  1. <?php
  2. if(ISSET($_POST['create'])){
  3. $content = $_POST['content'];
  4. $file_name = $_POST['filename'];
  5. $path = "files";
  6. $file = fopen($path."/".$file_name.".txt", 'w');
  7. fwrite($file, $content);
  8. fclose($file);
  9. header("location:index.php");
  10. }
  11. ?>

Virus note: All files are scanned once-a-day by for viruses, but new viruses come out every day, so no prevention program can catch 100% of them.


1. Re-scan downloaded files using your personal virus checker before using it.
2. NEVER, EVER run compiled files (.exe's, .ocx's, .dll's etc.)--only run source code.
