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 === $ch)   {   return false;   }      if (is_string($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($ch))   {   curl_close($ch);   return array(curl_error($ch), curl_errno($ch));   }   else   {   curl_close($ch);   if (!is_string($ret) || !strlen($ret))   {   return false;   }   return $ret;   }   }      function post($url, $fields, $userAgent = "", $httpHeaders = "", $username = "", $password = "")   {   $ret = Curl_Class::execute("POST", $url, $fields, $userAgent, $httpHeaders, $username, $password);   if (false === $ret)   {   return false;   }      if (is_array($ret))   {   return false;   }   return $ret;   }      function get($url, $userAgent = "", $httpHeaders = "", $username = "", $password = "")   {   $ret = Curl_Class::execute("GET", $url, "", $userAgent, $httpHeaders, $username, $password);   if (false === $ret)   {   return false;   }      if (is_array($ret))   {   return false;   }   return $ret;   }      function create()   {   $ch = null;   if (!function_exists("curl_init"))   {   return false;   }   $ch = curl_init();   if (!is_resource($ch))   {   return false;   }   return $ch;   }      }
