方法一（比较好，推荐）

//PHP发送短信 Monxin专用（PHP代码函数）

//本代码基于Monxin 运行

//代码来源：Monxin ./config/functions.php

function sms($config,$language,$pdo,$sender,$phone_number,$content){

//demo var_dump(sms(self::$config,self::$language,$pdo,"system","18074507509,15507455992","测试内容，时间".date("H:i:s",time())));

$sender=safe_str($sender);

$content=safe_str($content);

$arr=explode(',',$config['sms']['disable_phrase']);

$disable=false;

foreach($arr as $v){

if(strpos($content,$v)!==false){$phrase=$v;$disable=true;continue;}

}

if($disable){return $language['exist_disable_phrase']." ".$phrase;}

 

$phone_number=explode(',',$phone_number);

$phone_number=array_unique($phone_number);

$addressee='';

$count=0;

foreach($phone_number as $v){

if(preg_match($config['other']['reg_phone'],$v)){$addressee.=$v.',';}

}

$addressee=trim($addressee,',');

$addressee=explode(",",$addressee);

//var_dump($addressee);

$section=ceil(count($addressee)/$config['sms']['max']);

 

for($i=0;$i<$section;$i++){

$phone[$i]='';

for($j=$i*$config['sms']['max'];$j<($i+1)*$config['sms']['max'];$j++){

//echo $j.',';

if(isset($addressee[$j])){$phone[$i].=$addressee[$j].$config['sms']['delimiter'];}

}

$phone[$i]=trim($phone[$i],$config['sms']['delimiter']);

$temp=explode($config['sms']['delimiter'],$phone[$i]);

$count=count($temp);

$length=ceil(strlen(preg_replace('/[x80-xff]{3}/','x',$content))/($config['sms']['length']/2));

$count=$length*$count;

if(!isset($timing)){$timing=0;}

if($phone[$i]!=''){

$time=time();

$sql="insert into ".$pdo->index_pre."phone_msg (`sender`,`addressee`,`content`,`state`,`time`,`count`,`timing`) values

('$sender','".$phone[$i]."','".$content."','1','$time','$count','0')";

if($pdo->exec($sql)){

return send_sms($config,$pdo,$pdo->lastInsertId());

}else{

return false;

}

}

}

}

例2：在PHP5中通过file_get_contents函数发送短信（HTTP GET 方式）
PHP代码

<?php

$url = "http://sms.api.bz/fetion.php?username=13812345678&password=123456&sendto=13512345678&message=短信内容";

$result = file_get_contents($url);

echo $result; //返回信息默认为UTF-8编码的汉字，如果你的页面编码为gb2312，请使用下行语句输出返回信息。

//echo iconv("UTF-8", "GBK", $result);

?>

例3：在PHP中通过curl发送短信（HTTP POST 方式）
PHP代码

<?php

$data["username"] = 13812345678;

$data["password"] = "password123";

$data["sendto"] = 13512345678;

$data["message"] = "这是一条测试短信！";

 

$curl = new Curl_Class();

$result = @$curl->post("http://sms.api.bz/fetion.php", $data);

echo $result; //返回信息默认为UTF-8编码的汉字，如果你的页面编码为gb2312，请使用下行语句输出返回信息。

//echo iconv("UTF-8", "GBK", $result);

//curl类

class Curl_Class

{

function Curl_Class()

{

return true;

function execute($method, $url, $fields = '', $userAgent = '', $httpHeaders = '', $username = '', $password = '')

{

$ch = Curl_Class::create();

if (false === $ch)

{

}

 

if (is_string($url) && strlen($url))

{

$ret = curl_setopt($ch, CURLOPT_URL, $url);

}

else

{

return false;

}

//是否显示头部信息

curl_setopt($ch, CURLOPT_HEADER, false);

//

curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

 

if ($username != '')

{

curl_setopt($ch, CURLOPT_USERPWD, $username . ':' . $password);

}

 

$method = strtolower($method);

if ('post' == $method)

{

curl_setopt($ch, CURLOPT_POST, true);

if (is_array($fields))

{

$sets = array();

foreach ($fields AS $key => $val)

{

$sets[] = $key . '=' . urlencode($val);

}

$fields = implode('&',$sets);

}

curl_setopt($ch, CURLOPT_POSTFIELDS, $fields);

}

else if ('put' == $method)

{

curl_setopt($ch, CURLOPT_PUT, true);

}

 

//curl_setopt($ch, CURLOPT_PROGRESS, true);

//curl_setopt($ch, CURLOPT_VERBOSE, true);

//curl_setopt($ch, CURLOPT_MUTE, false);

curl_setopt($ch, CURLOPT_TIMEOUT, 10);//设置curl超时秒数

 

if (strlen($userAgent))

{

curl_setopt($ch, CURLOPT_USERAGENT, $userAgent);

}

 

if (is_array($httpHeaders))

{

curl_setopt($ch, CURLOPT_HTTPHEADER, $httpHeaders);

}

 

$ret = curl_exec($ch);

 

if (curl_errno($ch))

{

return array(curl_error($ch), curl_errno($ch));

}
