How can the use of functions like escape and unescape impact data integrity when updating database records in PHP?

The use of functions like escape and unescape can impact data integrity when updating database records in PHP if not used properly. These functions can lead to SQL injection vulnerabilities if input data is not properly sanitized before being passed to the database. To solve this issue, it is recommended to use prepared statements with parameterized queries to securely update database records. 

// Using prepared statements with parameterized queries to update database records securely
$stmt = $pdo->prepare("UPDATE table_name SET column_name = :value WHERE id = :id");
$stmt->bindParam(':value', $value);
$stmt->bindParam(':id', $id);
$stmt->execute();
