What potential issues can arise when using PHP to interact with an SMS server and retrieve data from a database?

One potential issue that can arise when using PHP to interact with an SMS server and retrieve data from a database is the lack of error handling. If there are errors in the code or if the server/database is unreachable, the script may fail without providing any useful information. To solve this, you can implement error handling using try-catch blocks to catch and handle any exceptions that may occur. 

try {
    // Code to interact with SMS server and retrieve data from the database
} catch (Exception $e) {
    echo 'An error occurred: ' . $e->getMessage();
}
