What potential issues or errors can arise when using cURL in PHP for API requests?

Issue: One potential issue that can arise when using cURL in PHP for API requests is not handling errors properly. If the API request fails for any reason, such as network issues or server errors, the cURL request may not return the expected response. To solve this, you should check for cURL errors and handle them appropriately in your code. 

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

// Close cURL session
curl_close($ch);
