What potential issues can arise from not setting a User-Agent in PHP requests to access server logs?

Not setting a User-Agent in PHP requests can lead to server logs being filled with entries that do not provide any useful information about the source of the request. This can make it difficult to track down and troubleshoot issues or identify potential security threats. To solve this issue, it is recommended to always set a User-Agent header in PHP requests to provide meaningful information about the client making the request. 

$url = 'http://example.com/api';
$userAgent = 'MyCustomUserAgent/1.0';

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_USERAGENT, $userAgent);

$response = curl_exec($ch);

curl_close($ch);

echo $response;
