我正在尝试通过 Ozeki 短信服务器使用 PHP 代码发送短信。我可以使用 Ozeki 提供的接口直接发送短信。但是这段 php 代码并没有像我预期的那样做同样的事情。我已连接到：127.0.0.1:9333(admin)。

它显示了
Fatal error: Maximum execution time of 30 seconds exceeded in C:\wamp\...\sendsms.php on line 32
哪些代码有$greeting = trim(fgets($ozekiSMSSocket,1000));
什么问题？

这是代码：

<?php 
include("sendsms.php");
$credits = sms_connect('127.0.0.1','9333','admin'); 

if ($credits>1) {
echo "Sending messages...<br>";
sms_send('+36203105366','Send SMS messages from a PHP client!');
}

echo "Receiving messages...<br>";
$inbox = sms_receive();
echo "$inbox";

sms_disconnect();
?>

这是中的代码sendsms.php

<?php
$ozekiSMSSocket = '';
$ozekiSMSCredit = 0;
function sms_connect($serverIP,$serverPort,$account) { 
global $ozekiSMSSocket;
global $ozekiSMSCredit;
$ret = true;
$ozekiSMSSocket = fsockopen($serverIP, $serverPort, $errno, $errstr, "60"); 

if ($errno) {
    echo $errstr;
    $ozekiSMSCredit = 0;
}

//$greeting = fgets($ozekiSMSSocket,1000);

$greeting = trim(fgets($ozekiSMSSocket,1000));
$randomstring = trim(fgets($ozekiSMSSocket,1000));

if (strlen($randomstring)) {
    $reply = md5($randomstring.$account).chr(13).chr(10);
    fputs($ozekiSMSSocket,$reply);
    $ozekiSMSCredit = trim(fgets($ozekiSMSSocket,1000));
}
return $ozekiSMSCredit;
}

function sms_send($msisdn,$msg) {
global $ozekiSMSSocket;
global $ozekiSMSCredit;
if ((isset($ozekiSMSSocket)) && ($ozekiSMSCredit>0)) {
    $msg=$msisdn.' '.$msg.chr(13).chr(10);
    fputs($ozekiSMSSocket,$msg);
} else {
    $ozekiSMSCredit = 0;
}
return $ozekiSMSCredit;
}

function sms_receive() {
global $ozekiSMSSocket;
$received = '';
if (isset($ozekiSMSSocket)) {
    $msg='OZEKI_INBOX'.chr(13).chr(10).'GET'.chr(13).chr(10);
    fputs($ozekiSMSSocket,$msg);
    $count = trim(fgets($ozekiSMSSocket,1000));
    for ($x=0;$x<$count;$x++) {
        $line = fgets($ozekiSMSSocket,1000);
        $received .= trim($line).chr(13).chr(10);
    }
}
return $received;
}

function sms_disconnect() {
global $ozekiSMSSocket;
if (isSet($ozekiSMSSocket)) fclose($ozekiSMSSocket);
}
?>

超时的原因是，您试图从套接字读取 1000 个字节，但服务器没有发送任何内容。

至于为什么“Ozeki 短信服务器”没有发送任何内容，我不知道。但是，如果您真的应该在连接后立即收到问候消息，则应该查看文档。通常，您希望客户端通过发送请求来启动通信。
