When using move_uploaded_file(). If the user uploads an image with a name that already exists, move_uploaded_file() will overwrite it. It's a good practice to store images in directories that you generate upon creating ur card/user/product etc...

<?php
    function generateDir(int $n): string {
         $characters="0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz";
        $dir = "";
        for($i = 0; $i<$n; $i++){
            $index = rand(0, strlen($characters)-1);
            $dir .= $characters[$index];
        }
        return $dir;
    }

    $image = $_FILES["image"];
    $imagePath = 'images/'. generateDir(10) .'/'. $image["name"];

    // Make the directory first or else it will not proceed with the upload.
    mkdir($imagePath);
    
    // some error handling etc...

    move_uploaded_file($image["tmp_name"],  $imagePath);
?>
