我一直在尝试使用下面的代码发送短信，但是当我循环时它没有发送。仅当我从数据库中选择一个数字时它才有效。我在数据库中有超过 5,000 个号码，并希望同时向所有号码发送短信，请帮助。
mysql_select_db($database_xxx, $xxx);
$query_rs = "SELECT phone FROM `notify` order by id asc LIMIT $l1 , $l2";
$rs= mysql_query($query_rs, $xxx) or die(mysql_error());
$row_rs = mysql_fetch_assoc($rs);
$totalRows_rs= mysql_num_rows($rs);
$phone = $row_rs['phone'];
// Do while loop to send sms.
while($row=mysql_fetch_assoc($rs)){
// Let's do some formatting and keep smiling.
$giringirin = ereg_replace("[^0-9]", "", $phone );
if (strlen($giringirin) == 11) {
$phone1=substr($giringirin, 1);
$phone= "234$phone1";
} elseif (strlen($giringirin) == 13){
$phone = $giringirin;
}
extract($_POST);
//set POST variables
$url = "http://sms.xxx.com/bulksms/bulksms.php?username=$username&password=$password&message=$smsmessage&mobile=$phone&sender=$sender";
$fields = array(
);
//url-ify the data for the POST
foreach($fields as $key=>$value) { $fields_string .= $key.'='.$value.'&'; }
rtrim($fields_string,'&');
//open connection
$ch = curl_init();
//set the url, number of POST vars, POST data
curl_setopt($ch,CURLOPT_URL,$url);
curl_setopt($ch,CURLOPT_POST,count($fields));
curl_setopt($ch,CURLOPT_POSTFIELDS,$fields_string);
//execute post
$result = curl_exec($ch);
if ($result == '1801') { echo "SMS has also been sent to the Customer ($phone) \n";} else { echo "Oooops, No sms was sent";}
//close connection
curl_close($ch);
}
