What are some common mistakes made during the installation of a PHP linklist that could lead to configuration errors?

One common mistake during the installation of a PHP linklist that could lead to configuration errors is incorrect database connection settings. Ensure that the database host, username, password, and database name are correctly configured in the PHP script. Another mistake is not setting the correct file permissions for directories where the linklist script needs to read and write files.

// Ensure correct database connection settings in the PHP script
$host = "localhost";
$username = "root";
$password = "password";
$database = "linklist_db";

// Connect to the database
$conn = new mysqli($host, $username, $password, $database);

if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}

// Set correct file permissions for directories
chmod("uploads/", 0755);
