<?php
if(isset($_POST['submit'])){
    $file = $_FILES['image'];

    // File properties
    $file_name = $file['name'];
    $file_tmp = $file['tmp_name'];
    $file_size = $file['size'];
    $file_error = $file['error'];

    // Get file extension
    $file_ext = strtolower(end(explode('.', $file_name)));

    // Allowed file extensions
    $allowed_ext = array('jpg', 'jpeg', 'png');

    if(in_array($file_ext, $allowed_ext)){
        if($file_error === 0){
            if($file_size <= 5242880){ // 5MB file size limit

                // Generate a unique name for the file
                $file_name_new = uniqid('', true) . '.' . $file_ext;

                // Set the file upload destination
                $file_destination = 'uploads/' . $file_name_new;

                // Move the file to the desired location
                if(move_uploaded_file($file_tmp, $file_destination)){
                    echo "File uploaded successfully.";
                } else {
                    echo "An error occurred while uploading the file.";
                }
            } else {
                echo "The file size exceeds the limit.";
            }
        } else {
            echo "An error occurred: " . $file_error;
        }
    } else {
        echo "Invalid file extension. Only JPG, JPEG, and PNG files are allowed.";
    }
}
?>

<!-- HTML form -->
<form action="upload.php" method="POST" enctype="multipart/form-data">
    <input type="file" name="image">
    <input type="submit" name="submit" value="Upload">
</form>


Please note that this is a basic example, and you may 
need to modify it to fit your specific requirements,
such as adding additional validation
or handling the uploaded file differently.
