Is it recommended to execute each SQL query individually instead of using mysqli_multi_query?

Executing each SQL query individually is recommended over using mysqli_multi_query because it allows for better error handling and debugging. When using mysqli_multi_query, it can be difficult to pinpoint which query caused an error if multiple queries are executed at once. By executing queries individually, you can easily identify and address any issues that may arise. 

// Example of executing SQL queries individually instead of using mysqli_multi_query

// Connect to the database
$mysqli = new mysqli("localhost", "username", "password", "database");

// Check connection
if ($mysqli->connect_error) {
    die("Connection failed: " . $mysqli->connect_error);
}

// SQL query 1
$query1 = "INSERT INTO table1 (column1, column2) VALUES ('value1', 'value2')";
if ($mysqli->query($query1) === TRUE) {
    echo "Query 1 executed successfully";
} else {
    echo "Error executing query 1: " . $mysqli->error;
}

// SQL query 2
$query2 = "UPDATE table2 SET column1 = 'new_value' WHERE column2 = 'value'";
if ($mysqli->query($query2) === TRUE) {
    echo "Query 2 executed successfully";
} else {
    echo "Error executing query 2: " . $mysqli->error;
}

// Close connection
$mysqli->close();
