In what scenarios would it be more efficient to use established binary container formats or SQLite instead of custom text file formats in PHP?

Using established binary container formats like JSON, XML, or SQLite can be more efficient than custom text file formats in PHP when dealing with complex data structures, large datasets, or when requiring advanced querying capabilities. These formats provide built-in serialization and deserialization methods, as well as indexing and querying functionalities, which can improve performance and simplify data manipulation tasks. 

// Example of using SQLite to store and query data
// Connect to SQLite database
$db = new SQLite3('data.db');

// Create a table to store data
$db->exec('CREATE TABLE IF NOT EXISTS users (id INTEGER PRIMARY KEY, name TEXT)');

// Insert data into the table
$db->exec("INSERT INTO users (name) VALUES ('John')");
$db->exec("INSERT INTO users (name) VALUES ('Jane')");

// Query data from the table
$results = $db->query('SELECT * FROM users');
while ($row = $results->fetchArray()) {
    echo $row['name'] . "\n";
}

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