What are the potential legal issues when using PHP to access external websites?

One potential legal issue when using PHP to access external websites is violating the website's terms of service or copyright laws by scraping or accessing their data without permission. To avoid legal issues, always check the website's terms of service for any restrictions on data access and consider obtaining permission before scraping their content. 

// Example of checking website's terms of service before accessing data
$website_url = 'https://www.example.com';
$terms_of_service_url = $website_url . '/terms-of-service';

// Check if website has terms of service
$terms_of_service = file_get_contents($terms_of_service_url);

if(strpos($terms_of_service, 'data access restrictions') !== false) {
    echo 'Please review the website\'s terms of service before accessing data.';
} else {
    // Proceed with accessing data from website
}
