方法一：
使用億速云短信擴展 https://github.com/yisu-cloud/sms

方法二：

<?php
function sendSms() {
    $url            = "https://api.yisu.com/sms/sendSms";
    $accessId       = "*****";
    $accessSecret   = "*****";
    $params = [
        "timestamp" => time(),
        "nonce"     => mt_rand(0, 99999999),
        "accessId"  => $accessId
    ];
    $params["phone"] = "13800000000";
    $params["templateCode"] = 100001;
    $params["templateVars"] = json_encode(["code"=>111111, "min"=>10], true);
    ksort($params);
    $signStr = "";
    foreach ( $params as $key => $value ) {
        $signStr = $signStr . $key . "=" . $value . "&";
    }
    $signStr = substr($signStr, 0, -1);
    $verifySignature = base64_encode(hash_hmac("sha1", $signStr, $accessSecret, true));
    $params["signature"] = $verifySignature;
    $data = http_build_query($params);
    $options = array(
        "http" => array(
            "method" => "POST",
            "header" => "Content-Type:application/x-www-form-urlencoded",
            "content" => $data
    ));
    $context  = stream_context_create($options);
    $result = file_get_contents($url, FILE_TEXT, $context);
    return $result;
}
echo sendSms();
?>
