Are there potential pitfalls in using file-based SQL inserts in PHP scripts?

Potential pitfalls in using file-based SQL inserts in PHP scripts include security vulnerabilities such as SQL injection if user input is not properly sanitized, as well as the risk of accidentally exposing sensitive database credentials if the file containing the SQL queries is accessible to unauthorized users. To mitigate these risks, it is recommended to use prepared statements with parameterized queries to prevent SQL injection attacks and store the file containing SQL inserts in a secure location that is not accessible to the public.

<?php
// Connect to database
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "database";

$conn = new mysqli($servername, $username, $password, $dbname);

// Read SQL insert queries from file
$sqlFile = "sql_inserts.sql";
$sqlQueries = file_get_contents($sqlFile);

// Use prepared statements to execute SQL queries
if ($conn->multi_query($sqlQueries)) {
    echo "SQL inserts executed successfully";
} else {
    echo "Error executing SQL inserts: " . $conn->error;
}

// Close database connection
$conn->close();
?>
