You can try the example from this link:
您可以尝试此链接中的示例:
<?php
$fp = fsockopen("www.example.com", 80, $errno, $errstr, 30);
if (!$fp) {
echo "$errstr ($errno)<br />\n";
} else {
$out = "GET / HTTP/1.1\r\n";
$out .= "Host: www.example.com\r\n";
$out .= "Connection: Close\r\n\r\n";
fwrite($fp, $out);
while (!feof($fp)) {
echo fgets($fp, 128);
}
fclose($fp);
}
?>

You can create a socket with socket_create, open it with socket_connect and write with socket_write. socket_write documentation on php.net
您可以使用 socket_create 创建一个套接字,使用 socket_connect 打开它并使用 socket_write 写入。php.net 上的 socket_write 文档
