To check if a MySQL server is connected in an ExeOutput for PHP application, you can use PHP’s MySQLi extension.
First, enable the MySQLi PHP extension to allow your PHP application to interact with MySQL. To do this, go to the PHP Settings -> PHP Extensions page in ExeOutput for PHP.
Then, use the following PHP code to check the connection and display an alert if it fails:
<?php
// Database connection parameters
$host = 'localhost'; // MySQL server host
$username = 'your_username'; // MySQL username
$password = 'your_password'; // MySQL password
$database = 'your_database'; // MySQL database name
// Create a new MySQLi connection
$connection = new mysqli($host, $username, $password, $database);
// Check the connection
if ($connection->connect_error) {
// Connection failed; display an alert
echo "<script>alert('MySQL connection failed: " . $connection->connect_error . "');</script>";
} else {
// Connection successful
echo "Successfully connected to the MySQL server.";
}
// Close the database connection
$connection->close();
?>
