How can the use of the empty function in PHP be utilized to prevent syntax errors in MySQL queries?

When constructing MySQL queries in PHP, it's important to ensure that variables used in the query are not empty to prevent syntax errors. One way to achieve this is by using the `empty()` function to check if the variable has a value before including it in the query. This helps prevent errors that may occur if an empty variable is concatenated into the query string. 

// Example of using the empty function to prevent syntax errors in MySQL queries
$name = "John Doe";
$email = "";

// Check if variables are not empty before including them in the query
if(!empty($name) && !empty($email)) {
    $query = "INSERT INTO users (name, email) VALUES ('$name', '$email')";
    // Execute the query
} else {
    echo "Name and email must be provided.";
}
