What potential issues or errors could arise when using cURL in PHP?

One potential issue when using cURL in PHP is not handling errors properly, which can lead to unexpected behavior or security vulnerabilities. To solve this, it is important to check for errors after each cURL request and handle them accordingly, such as logging the error or displaying a user-friendly message. 

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

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

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

// Check for errors
if(curl_errno($ch)) {
    $error_message = curl_error($ch);
    // Handle the error, such as logging it or displaying a message
}

// Close cURL session
curl_close($ch);
