Are there specific considerations or limitations to be aware of when using MySQLi commands in PHP scripts that could impact memory usage and performance?

When using MySQLi commands in PHP scripts, it's important to be mindful of memory usage and performance. One common issue is not properly freeing up memory after executing queries, which can lead to memory leaks and degraded performance over time. To address this, make sure to explicitly free up memory by using the `mysqli_free_result()` function after executing SELECT queries. 

// Execute a SELECT query
$result = $mysqli->query("SELECT * FROM table_name");

// Fetch data from the result set
while ($row = $result->fetch_assoc()) {
    // Process the data
}

// Free up memory after fetching data
mysqli_free_result($result);
