Example analysis of PHP hooks and simple distribution methods

This article mainly introduces PHP hooks and simple distribution methods, combined with examples of the definition and use of PHP hooks, and the implementation of the multi-channel free switch, the need for friends can refer to the next

This article describes the PHP hooks and simple distribution methods. Share to everyone for your reference, as follows:

The simple hook implementation example class tool{  public static function main ($class, $fun, $data = ") {    //Pre-common operation    $con = new $class; 
  
    $con $fun ($data);    Post-public Operation  }}class a{  function B ($data) {    echo ' I am method B ';  }} Class c{  function D ($data) {    echo ' I am method d ';  }} The hook calls Tool::main (' a ', ' B ', ' 222 ');
  

This was intended to be achieved with hooks when encapsulating the SMS channel.

can automatically send SMS (multi-channel) Email,push and other messages ...

Later found that business requirements are not as complex as imagined, development is shelved ....

T_T then adopted a simple distribution method to achieve

Class ar_sms{Const Lanchuang = 1;//Channel 1 Const ALIDAYU = 2;//channel 2 private $type; Private $chuanglan _config = Array (//Channel 1 configuration item ' api_send_url ' = ' xxxx ', ' api_balance_query_url ' = ' xxxxx ', ' Api_  Account ' = ' xxxx ', ' api_password ' = ' xxxxx ',); Private $alidayu _config = Array (//Channel 2 configuration item ' Api_key ' = ' xxxx ', ' api_id ' = ' xxxxx ', ' api_send_url ' = ' xxxxx '  ',  );      Public function __construct ($type =1) {switch ($type) {case Self::lanchuang: $this->type = $type;      Case Self::alidayu: $this->type = $type;    Default: $this->type = false; }}//Outbound Send method Public function sendsms ($mobile, $msg) {switch ($this->type) {case Self::lanchuang:re      Turn $this->_SENDCL ($mobile, $msg);      Case Self::alidayu:return $this->_sendal ($mobile, $msg);    Default:return false; }}//Channel 1 Send method Private function _SENDCL ($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 ' =&G T    $EXTNO);    $result = $this->_curlpost ($this->chuanglan_config[' Api_send_url '), $POSTARR);    $result = $this->_execresult ($result); return $result [1] = = 0?  true: $result [1]; }//Channel 2 Send method Private function _sendal ($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: $result [1]; }//-------------Some public methods/** * Process return value \ r \ n Split * */Private Function _execresult ($result) {$result =preg_split ("/[, \r\n]/", $resuLT);  return $result;    }/** * Process return value JSON * */Private Function _jsonresult ($result) {$result =json_decode ($result, true);  return $result; /** * Send HTTP request via Curl * @param string $url//Request URL * @param array $postFields//Request parameter * @return Mixed */Priva    Te function _curlpost ($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);//Channel 1 sends $res = $OB->sendsms (' xxxxx ', ' xxxxxx '); Var_dump ($res); $ob = new Ar_sms (Ar _sms::lanchuang)///Channel 2 Send $res = $ob->sendsms (' xxxxx ', ' xxxxxx '); Var_dump ($res);

A simple distribution enables the free switching of multiple channels,

Because it's just a simple send, there's no further abstraction ~ embarrassing Orz

The implementation of the hook, the idea is a bit large, concrete implementation is also with the elegant. I'm going to look into it sometime. Let's just throw a simple demo. The idea is--"multi-channel multi-mode multichannel support for easy expansion
