What potential issues should be considered when using LAST_INSERT_ID() in PHP?

When using LAST_INSERT_ID() in PHP, one potential issue to consider is that it returns the last automatically generated value by an INSERT statement, which may not always be the value you expect if multiple INSERT statements are executed simultaneously. To ensure the correct value is retrieved, it's recommended to use the mysqli_insert_id() function instead, which is specific to the MySQLi extension in PHP. 

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

// Perform an INSERT statement
$connection->query("INSERT INTO table_name (column_name) VALUES ('value')");

// Retrieve the last inserted ID
$last_insert_id = $connection->insert_id;

// Close the database connection
$connection->close();
