Have you considered capturing MySQL errors to troubleshoot potential connection or syntax problems?

When working with MySQL databases in PHP, it is important to capture any errors that may occur during connection or query execution. This can help troubleshoot potential issues such as connection problems or syntax errors in SQL queries. By using the mysqli_error() function, you can retrieve the error message generated by MySQL and handle it accordingly in your PHP code. 

// Establish connection to MySQL database
$connection = mysqli_connect("localhost", "username", "password", "database");

// Check for connection errors
if (mysqli_connect_errno()) {
    echo "Failed to connect to MySQL: " . mysqli_connect_error();
    exit();
}

// Perform SQL query
$query = "SELECT * FROM table";
$result = mysqli_query($connection, $query);

// Check for query errors
if (!$result) {
    echo "Error in SQL query: " . mysqli_error($connection);
    exit();
}

// Process query results
while ($row = mysqli_fetch_assoc($result)) {
    // Do something with the data
}

// Close connection
mysqli_close($connection);
