What are the potential pitfalls of using fopen or file_get_contents to fetch data from external sources like Yahoo Finance in PHP scripts?

One potential pitfall of using fopen or file_get_contents to fetch data from external sources like Yahoo Finance in PHP scripts is that it may not handle errors or timeouts gracefully, leading to potential script failures or delays. To solve this issue, it is recommended to use cURL, which provides more robust error handling and timeout options. 

// Using cURL to fetch data from Yahoo Finance
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'https://finance.yahoo.com/your_endpoint_here');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_TIMEOUT, 10); // Set timeout to 10 seconds
$data = curl_exec($ch);

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

curl_close($ch);

// Process $data as needed
