Headers. Headers. Headers. I can’t stress this enough—curl to PHP fails often because of missing or malformed headers. Use `curl_setopt($ch, CURLOPT_HTTPHEADER, $headers)` and pass an array like:
```php
$headers = [
'Authorization: Bearer token123',
'Content-Type: application/json'
];
```
Also, check out PHP’s `CURLOPT_FOLLOWLOCATION` if you’re dealing with redirects.
```php
$headers = [
'Authorization: Bearer token123',
'Content-Type: application/json'
];
```
