How can PHP developers avoid errors related to incorrect syntax when querying data from a MySQL database?

To avoid errors related to incorrect syntax when querying data from a MySQL database, PHP developers should use prepared statements with parameterized queries. This approach helps prevent SQL injection attacks and ensures that data is properly sanitized before being executed in the database query. 

// Establish a connection to the MySQL database
$mysqli = new mysqli("localhost", "username", "password", "database");

// Prepare a parameterized query using placeholders
$stmt = $mysqli->prepare("SELECT * FROM table WHERE column = ?");

// Bind parameters to the placeholders and execute the query
$stmt->bind_param("s", $value);
$value = "example";
$stmt->execute();

// Fetch the results
$result = $stmt->get_result();

// Process the fetched data
while ($row = $result->fetch_assoc()) {
    // Do something with the data
}

// Close the statement and the database connection
$stmt->close();
$mysqli->close();
