How can PHP developers efficiently manage database schema changes and table existence checks in SQLite databases?

Managing database schema changes and table existence checks in SQLite databases can be efficiently handled by using PHP migration scripts. These scripts can be used to create, update, or delete tables and columns in the database based on version control. By using migration scripts, developers can easily track and manage changes to the database schema over time. 

<?php

// Connect to SQLite database
$db = new SQLite3('database.db');

// Check if a table exists in the database
$tableExists = $db->querySingle("SELECT COUNT(*) FROM sqlite_master WHERE type='table' AND name='my_table'");

// If table does not exist, create it
if (!$tableExists) {
    $db->exec("CREATE TABLE my_table (id INTEGER PRIMARY KEY, name TEXT)");
}

// Perform any other necessary schema changes using migration scripts

$db->close();

?>
