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">Check File Exist Using PHP</h3>
  16. <hr style="border-top:1px dotted #ccc;"/>
  17. <div class="col-md-8">
  18. <form method="POST" action="">
  19. <div class="form-inline">
  20. <label>File Name:</label>
  21. <input type="text" class="form-control" name="file" required="required"/><button class="btn btn-primary" name="check">Check</button>
  22. </div>
  23. </form>
  24. <?php include'check_file.php'?>
  25. <br />
  26. <table class="table table-bordered">
  27. <thead class='alert-info'>
  28. <tr>
  29. <th><center>Files in folder</center></th>
  30. </tr>
  31. </thead>
  32. <tbody>
  33. <?php
  34. $files = scandir('file/');
  35. foreach ($files as $file){
  36. if($file != '.' && $file !='..'){
  37. $path = "file/".$file;
  38. ?>
  39. <tr>
  40. <td><?php echo $file?></td>
  41. </tr>
  42. <?php
  43. }
  44. }
  45. ?>
  46. </tbody>
  47. </table>
  48. </div>
  49. </div>
  51. </body>
  52. </html>

Creating the Main Function

This code contains the main function of the application. This will dynamically check whether a certain file is existed. To make this just copy and write these block of codes below inside the text editor, then save it as check_file.php

  1. <?php
  2. if(ISSET($_POST['check'])){
  3. $filename = $_POST['file'];
  4. if(file_exists('file/'.$filename)){
  5. echo "<center class='alert-success'><h4>File ".$filename." is available!</h4></center>";
  6. }else{
  7. echo "<center class='alert-danger'><h4>File ".$filename." is not available!</h4></center>";
  8. }
  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.
