What are some potential pitfalls when using preg_split to break down SQL queries in PHP?

One potential pitfall when using preg_split to break down SQL queries in PHP is that it may not handle all possible SQL syntax variations correctly, leading to unexpected results or errors. To avoid this, consider using a more robust SQL parser library or manually parsing the SQL query to ensure accurate breakdown. 

// Example using preg_split to break down SQL queries
$sql = "SELECT * FROM users WHERE id = 1";
$parts = preg_split("/\s+/", $sql);

// Improved approach using a SQL parser library or manual parsing
// Example using Aura.SqlParser library
use Aura\SqlParser\Parser;
$parser = new Parser($sql);
$parsedQuery = $parser->parse();
$parts = $parsedQuery->getStatement();
