What potential pitfalls should be considered when accessing the same database for different scripts in PHP?

When accessing the same database for different scripts in PHP, potential pitfalls to consider include data consistency issues, concurrent access problems, and performance bottlenecks. To solve these issues, you can implement proper locking mechanisms, transactions, and connection pooling to ensure data integrity and optimize database operations. 

// Example code snippet demonstrating the use of transactions in PHP to ensure data consistency when accessing the same database for different scripts

// Start a transaction
$pdo->beginTransaction();

// Perform database operations within the transaction
$stmt = $pdo->prepare("INSERT INTO table_name (column1, column2) VALUES (:value1, :value2)");
$stmt->bindParam(':value1', $value1);
$stmt->bindParam(':value2', $value2);
$stmt->execute();

// Commit the transaction
$pdo->commit();
