Here is a simple HTTP client that leverages the socket
extension in order to download a webpage directly.
<?php
error_reporting (E_ALL);
/* Get the port for the WWW service. */
$service_port = getservbyname ('www', 'tcp');
/* Get the IP address for the target host. */
$address = gethostbyname ('www.php.net');
/* Create a TCP/IP socket. */
$socket = socket_create (AF_INET, SOCK_STREAM, 0);
if ($socket < 0) {
echo "socket_create() failed: reason: " . socket_strerror ($socket) . "\n";
}
$result = socket_connect ($socket, $address, $service_port);
if ($result < 0) {
echo "socket_connect() failed.\nReason: ($result) " . socket_strerror($result) . "\n";
}
$in = "HEAD / HTTP/1.0\r\n\r\n";
$out = '';
socket_write ($socket, $in, strlen ($in));
while ($out = socket_read ($socket, 2048)) {
echo $out;
}
socket_close ($socket);
?>
