Submitted by razormist on Tuesday, June 30, 2020 - 19:51.

In this code we will tackle about Check File Exist using PHP. The code will check the file if exist in the folder when a filename is entered. This is a user-friendly kind of program feel free to modify it. To learn more about this tutorial, just follow the step below.

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">Check File Exist Using PHP</h3>
                <hr style="border-top:1px dotted #ccc;"/>
                <div class="col-md-8">
                        <form method="POST" action="">
                                <div class="form-inline">
                                        <label>File Name:</label>
                                        <input type="text" class="form-control" name="file" required="required"/><button class="btn btn-primary" name="check">Check</button>
                                </div>
                        </form>
                        <?php include'check_file.php'?>
                        <br />
                        <table class="table table-bordered">
                                <thead class='alert-info'>
                                        <tr>
                                                <th><center>Files in folder</center></th>
                                        </tr>
                                </thead>
                                <tbody>
                                        <?php
                                                $files = scandir('file/');
                                                foreach ($files as $file){
                                                        if($file != '.' && $file !='..'){
                                                                $path = "file/".$file;
                                        ?>
                                        <tr>
                                                <td><?php echo $file?></td>
                                        </tr>
                                        <?php
                                                        }
                                                }
                                        ?>
                                </tbody>
                        </table>
                </div>
        </div>
 
</body>
</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

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