What potential issue could be causing the data not to be saved in the database when using a PHP script?

One potential issue could be that there is an error in the SQL query being used to insert the data into the database. To solve this issue, you should check the query for any syntax errors or missing parameters. Another potential issue could be that there is a problem with the database connection, such as incorrect credentials or a server issue. Make sure to double-check the database connection details in your PHP script. 

// Check for errors in the SQL query
$sql = "INSERT INTO table_name (column1, column2) VALUES ('$value1', '$value2')";
if(mysqli_query($conn, $sql)){
    echo "Data saved successfully";
} else{
    echo "Error: " . $sql . "<br>" . mysqli_error($conn);
}

// Check the database connection
$conn = mysqli_connect($servername, $username, $password, $dbname);
if (!$conn) {
    die("Connection failed: " . mysqli_connect_error());
}
