In what situations should PHP developers consider seeking outside help for coding issues?

If a PHP developer encounters a complex coding issue that they are unable to solve after thorough research and troubleshooting, it may be beneficial to seek outside help. This could include reaching out to online forums, consulting with more experienced developers, or hiring a professional consultant. Seeking outside help can provide fresh perspectives and insights that may lead to a quicker resolution of the problem.

// Example code snippet showcasing how to connect to a MySQL database using PHP

$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "myDB";

// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);

// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}
echo "Connected successfully";
