What are the potential reasons for a script using PHP not working as expected when inserting data into a MySQL database?

The potential reasons for a PHP script not working as expected when inserting data into a MySQL database could include incorrect database connection details, SQL syntax errors, or insufficient user permissions. To solve this issue, ensure that the database connection details are correct, double-check the SQL query syntax for any errors, and verify that the user has the necessary permissions to insert data into the database. 

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

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

// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}

// Sample SQL query to insert data into a table
$sql = "INSERT INTO table_name (column1, column2) VALUES ('value1', 'value2')";

if ($conn->query($sql) === TRUE) {
    echo "New record created successfully";
} else {
    echo "Error: " . $sql . "<br>" . $conn->error;
}

$conn->close();
?>
