What are the potential drawbacks of relying on REGEX to split a large SQL file into individual table files?

One potential drawback of relying on REGEX to split a large SQL file into individual table files is that REGEX may not be able to accurately handle all possible variations in SQL syntax. To solve this issue, it is recommended to use a more robust SQL parser library that can accurately parse and split the SQL file. 

// Using an SQL parser library to split a large SQL file into individual table files
require 'vendor/autoload.php'; // Include the SQL parser library

$sql = file_get_contents('large_sql_file.sql'); // Read the large SQL file

$parser = new PHPSQLParser\Parser(); // Initialize the SQL parser

$queries = $parser->parse($sql); // Parse the SQL file into individual queries

foreach ($queries as $query) {
    if ($query['type'] == 'CREATE') {
        $table_name = $query['TABLE']['no_quotes']['parts'][0]; // Get the table name
        $table_sql = $query['raw']; // Get the SQL for the table
        file_put_contents($table_name . '.sql', $table_sql); // Write the table SQL to a file
    }
}
