PHP bruger libcurl-biblioteket oprettet af Daniel Stenberg til at oprette forbindelse til forskellige servere. De protokoller, det understøtter, er http、https、ftp、gopher、telnet、dict、file、ldap. Libcurl understøtter også HTTPS-certifikater, POST, PUT, FTP osv. Det understøtter også form-baseret upload, proxy, cookies, brugernavn + adgangskodegodkendelse.

PHP bruger cURL-biblioteket til at starte disse HTTP-anmodninger. cURL afhænger af libcurl7.10.5 eller derover.

I PHP 5.4 eller tidligere er indkapslingen af ​​cURL-uploadfiler proceduremæssig:

$ch = curl_init();
$data = array('name' => 'File1', 'file' => '@/path/to/file.png');
curl_setopt($ch, CURLOPT_URL, 'https://localhost/upload.php');
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_SAFE_UPLOAD, false);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
curl_exec($ch);

I PHP 5.5 eller nyere opdateres indkapslingen af ​​cURL-uploadfilen til CURLFille-klassen:

$ch = curl_init();
$data = array('name' => 'File1', 'file' => new CURLFille('/path/to/file.png'));
curl_setopt($ch, CURLOPT_URL, 'https://localhost/upload.php');
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_SAFE_UPLOAD, false);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
curl_exec($ch);
