How can configuration files affect PHP web service calls?

Configuration files can affect PHP web service calls by storing important information such as API keys, endpoints, and other settings needed for the service to function correctly. By properly configuring these files, PHP scripts can easily access and utilize this information when making web service calls. To ensure secure and efficient web service calls, it is crucial to properly manage and update configuration files as needed. 

// Example of using a configuration file to store API key and endpoint for a web service call

// config.php
<?php
return [
    'api_key' => 'your_api_key_here',
    'endpoint' => 'https://api.example.com'
];

// script.php
$config = include 'config.php';

$api_key = $config['api_key'];
$endpoint = $config['endpoint'];

// Make web service call using $api_key and $endpoint
