Example analysis of PHP hooks and simple distribution methods

This article mainly introduces PHP hooks and simple distribution methods. It analyzes the definition and use of PHP hooks in the form of examples, as well as the implementation skills of free switching between multiple channels. Friends in need can refer to it

The examples in this article describe PHP hooks and simple distribution methods. Share it with everyone for your reference, the details are as follows:

//简单的钩子实现例子
class tool{
  public static function main($class, $fun, $data = ''){
    //前置公共操作
    $con = new $class;
    $con->$fun($data);
    //后置公共操作
  }
}
class a{
  function b($data){
    echo '我是方法b';
  }
}
class c{
  function d($data){
    echo '我是方法d';
  }
}
//钩子调用
tool::main('a','b','222');

I planned to use hooks when encapsulating the SMS channel,

can Automatically send SMS (multi-channel) email, push and other messages. . .

Later, it was discovered that the business requirements were not as complex as imagined, so the development was shelved. . . .

T_T So we adopted a simple distribution method to achieve

class Ar_Sms{
  const LANCHUANG = 1;//通道1
  const ALIDAYU = 2; //通道2
  private $type;
  private $chuanglan_config = array(//通道1配置项
    'api_send_url'=>'xxxx',
    'api_balance_query_url'=> 'xxxxx',
    'api_account'=> 'xxxx',
    'api_password'=> 'xxxxx',
  );
  private $alidayu_config = array(//通道2配置项
    'api_key'=> 'xxxx',
    'api_id'=> 'xxxxx',
    'api_send_url'=> 'xxxxx',
  );
  public function __construct($type=1){
    switch($type){
      case self::LANCHUANG:
        $this->type = $type;break;
      case self::ALIDAYU:
        $this->type = $type;break;
      default:
        $this->type = false;
    }
  }
  //对外抛出的发送方法
  public function sendSms($mobile, $msg){
    switch($this->type){
      case self::LANCHUANG:
        return $this->_sendCL($mobile, $msg);
      case self::ALIDAYU:
        return $this->_sendAL($mobile, $msg);
      default:
        return false;
    }
  }
  //通道1发送方法
  private function _sendCL($mobile, $msg, $needstatus = 'false', $extno = ''){
    $postArr = array (
      'account' => $this->chuanglan_config['api_account'],
      'pswd' => $this->chuanglan_config['api_password'],
      'msg' => $msg,
      'mobile' => $mobile,
      'needstatus' => $needstatus,
      'extno' => $extno
    );
    $result = $this->_curlPost( $this->chuanglan_config['api_send_url'] , $postArr);
    $result = $this->_execResult($result);
    return $result[1] == 0 ? true : $result[1];
  }
  //通道2发送方法
  private function _sendAL($mobile, $msg){
    $postArr = array (
      'id' => $this->alidayu_config['api_id'],
      'key' => $this->alidayu_config['api_key'],
      'msg' => $msg,
      'mobile' => $mobile,
    );
    $result = $this->_curlPost( $this->alidayu_config['api_send_url'] , $postArr);
    $result = $this->_execResult($result);
    return $result[1] == 0 ? true : $result[1];
  }
  //-------------一些公共方法
  /**
   * 处理返回值\r\n 分割
   *
   */
  private function _execResult($result){
    $result=preg_split("/[,\r\n]/",$result);
    return $result;
  }
  /**
   * 处理返回值json
   *
   */
  private function _jsonResult($result){
    $result=json_decode($result, true);
    return $result;
  }
  /**
   * 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){
    $postFields = http_build_query($postFields);
    $ch = curl_init ();
    curl_setopt ( $ch, CURLOPT_POST, 1 );
    curl_setopt ( $ch, CURLOPT_HEADER, 0 );
    curl_setopt ( $ch, CURLOPT_RETURNTRANSFER, 1 );
    curl_setopt ( $ch, CURLOPT_URL, $url );
    curl_setopt ( $ch, CURLOPT_POSTFIELDS, $postFields );
    $result = curl_exec ( $ch );
    curl_close ( $ch );
    return $result;
  }
}
$ob = new Ar_Sms(Ar_Sms::ALIDAYU);//通道1发送
$res = $ob->sendSms('xxxxx','xxxxxx');
var_dump($res);
$ob = new Ar_Sms(Ar_Sms::LANCHUANG);//通道2发送
$res = $ob->sendSms('xxxxx','xxxxxx');
var_dump($res);

Achieve free switching of multiple channels through a simple distribution,

Since it is just a simple sending, there is no further abstraction~囧orz

The idea of ​​how to implement the hook is a bit big, and the specific implementation still needs to be considered. . I will study it when I have time. Here is a simple demo. The idea is-"Multiple channels, multi-methods, and multi-channel support for easy expansion
