How does php implement the function of sending verification codes? ?

PHP implements sending SMS verification code:

1. html code

<li>
<span>手机号码:</span>
<input type="text" placeholder="手机号码" name="telephone">
</li>
<li>
<span>验证码:</span>
<input type="text" placeholder="短信验证码" name="phonecode">
<span class="code_btn" onclick ="return get_svg();">获取验证码</span>
</li>

2.js code

/**
 * 发送验证码
 * @return {[type]} [description]
 */
function get_svg() {
var phone = $("input[name='telephone']").val();
 
if (!(/^1[34578]\d{9}$/.test(phone))) {
layer.msg("请正确输入手机号！");
return false;
}
 
var url = "/msm/sendmsm/phone/" + phone;
$.get(url, function (resdata) {
console.log(resdata);
layer.msg(resdata.data);
if (resdata.type == 1) {
$(".code_btn").attr('onclick', "return false;");
listion_sendmsm();
}
})
return false;
}
 
function listion_sendmsm() {
var time = 61;
setTime = setInterval(function () {
if (time <= 1) {
clearInterval(setTime);
$(".code_btn").text("再发一次");
$(".code_btn").attr(&#39;onclick&#39;, "return get_svg();");
return;
}
time--;
$(".code_btn").text(time + "s");
 
}, 1000);
}

3. PHP code implementation

Msm.php

/**
 * 发送短信
 * @author 
 * @return [type] [description]
 */
public function sendmsm()
{
$phone = input('phone');
 
if(!$phone){
return WPreturn('请输入手机号码！',-1);
}
 
$code = rand(1000,9999);
$_SESSION['code'] = $code;
$res = sendmessage($code ,$phone);
if($res){
return WPreturn('发送成功',1);
}else{
return WPreturn('发送验证码失败！',-1);
}
}
 
/* *
* 类名：ChuanglanSmsApi
* 功能：创蓝短信接口请求类
* 详细：构造创蓝短信接口请求，获取远程HTTP数据
* 说明：

*/
public function sendmessage($code, $telephone)
{
$conf = getconf('');
 
if(!$code){
return false;
}
 
if(!$telephone){
return false;
}
$content = "您的验证码是：{$code}，如非本人操作，请忽略此短信。";
//创蓝接口参数
$postArr = array (
'account'  =>  $conf['msm_appkey'],
'password' => $conf['msm_secretkey'],
'msg' => urlencode($content),
'phone' => $telephone,
'report' => true
);
 
$result = $this->curlPost("http://smssh1.253.com/msg/send/json", $postArr);
$json = json_decode($result);
if($json -> code != 0){
return false;
}else{
return true;
}
}
 
/**
 * 通过CURL发送HTTP请求
 * @param string $url  //请求URL
 * @param array $postFields //请求参数 
 * @return mixed
 *  
 */
private function curlPost($url,$postFields){
$postFields = json_encode($postFields);
$ch = curl_init ();
curl_setopt( $ch, CURLOPT_URL, $url ); 
curl_setopt( $ch, CURLOPT_HTTPHEADER, array(
'Content-Type: application/json; charset=utf-8'   //json版本需要填写  Content-Type: application/json;
)
);
curl_setopt($ch, CURLOPT_IPRESOLVE, CURL_IPRESOLVE_V4); 
curl_setopt( $ch, CURLOPT_RETURNTRANSFER, 1 );
curl_setopt( $ch, CURLOPT_POST, 1 );
curl_setopt( $ch, CURLOPT_POSTFIELDS, $postFields);
curl_setopt( $ch, CURLOPT_TIMEOUT,60); 
curl_setopt( $ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt( $ch, CURLOPT_SSL_VERIFYPEER, 0);
$ret = curl_exec ( $ch );
if (false == $ret) {
$result = curl_error(  $ch);
} else {
$rsp = curl_getinfo( $ch, CURLINFO_HTTP_CODE);
if (200 != $rsp) {
$result = "请求状态 ". $rsp . " " . curl_error($ch);
} else {
$result = $ret;
}
}
curl_close ( $ch );
return $result;
}
