What potential issues or pitfalls should be considered when using PHP to access secure resources like Jenkins with authentication?

One potential issue when using PHP to access secure resources like Jenkins with authentication is the risk of exposing sensitive credentials in the code. To mitigate this risk, it is recommended to store the credentials in a secure location, such as environment variables or a configuration file outside of the web root. Additionally, using HTTPS for communication can help secure the transmission of sensitive data. 

// Example of securely storing credentials in environment variables
$jenkins_username = getenv('JENKINS_USERNAME');
$jenkins_password = getenv('JENKINS_PASSWORD');

// Example of making a secure request to Jenkins using cURL
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'https://jenkins.example.com/api/json');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_BASIC);
curl_setopt($ch, CURLOPT_USERPWD, "$jenkins_username:$jenkins_password");

$response = curl_exec($ch);

if(curl_errno($ch)){
    echo 'Error: ' . curl_error($ch);
}

curl_close($ch);

echo $response;
