Are there any best practices or guidelines for structuring and organizing SQL queries in PHP to avoid syntax errors or inconsistencies, especially when using multi_queries?

When structuring and organizing SQL queries in PHP, it is important to properly handle syntax errors and inconsistencies, especially when using multi_queries. One best practice is to separate each query into its own variable and execute them individually to avoid confusion and potential errors.

// Example of structuring and organizing SQL queries in PHP to avoid syntax errors or inconsistencies
$query1 = "SELECT * FROM table1";
$query2 = "SELECT * FROM table2";

// Execute the queries individually
$result1 = $conn->query($query1);
$result2 = $conn->query($query2);

// Handle the results as needed
if ($result1 && $result2) {
    // Process the results
} else {
    echo "Error executing queries";
}
