How can PHP developers effectively troubleshoot and debug issues related to sending commands to APIs using curl functions?

To effectively troubleshoot and debug issues related to sending commands to APIs using curl functions in PHP, developers can use error handling techniques such as checking for curl errors, inspecting the response headers and body, and enabling verbose output for detailed information on the request and response. 

// Initialize curl session
$ch = curl_init();

// Set curl options
curl_setopt($ch, CURLOPT_URL, 'https://api.example.com');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

// Execute curl request
$response = curl_exec($ch);

// Check for errors
if(curl_errno($ch)) {
    echo 'Curl error: ' . curl_error($ch);
}

// Close curl session
curl_close($ch);

// Debug information
var_dump($response);
