In what ways can server configuration changes, such as moving from PHP 7.0 to PHP 7.3, impact the functionality of PHP scripts that interact with external resources?

When server configuration changes, such as upgrading from PHP 7.0 to PHP 7.3, it can impact the functionality of PHP scripts that interact with external resources due to changes in syntax or deprecated functions. To address this issue, developers need to update their PHP scripts to ensure compatibility with the new PHP version. This may involve modifying code to use updated functions or adjusting configurations to accommodate any changes in behavior. 

// Example of updating PHP script to use updated functions for interacting with external resources
// Before PHP 7.3
$response = file_get_contents('https://api.example.com/data');

// After PHP 7.3
$context = stream_context_create(['http' => ['ignore_errors' => true]]);
$response = file_get_contents('https://api.example.com/data', false, $context);
