针对thinkPHP5框架存储过程bug重写的存储过程扩展类完整实例

本文实例讲述了针对thinkPHP5框架存储过程bug重写的存储过程扩展类。分享给大家供大家参考，具体如下：

近期用tp5框架调取存储过程发现有bug，借鉴了一些官方的函数、以及找了个mysqli的类把存储过程重新写了个扩展类，下面两个类直接放置项目extend目录的stored（这个文件夹名称请按个人习惯命名）目录下，需要注意的是类增加命名空间namespace stored就OK。

1、mysqli类,此类直接在网上找的，新增一个getAllData()的函数来获取存储过程多条数据集

host = $config['hostname'] ? $config['hostname'] : 'localhost';
    $this->port = $config['hostport'] ? $config['hostport'] : '3306';
    $this->user = $config['username'] ? $config['username'] : 'root';
    $this->pass = $config['password'] ? $config['password'] : 'root';
    $this->db = $config['database'] ? $config['database'] : 'zhijian';
    $this->charset=isset($config['charset']) ? $config['charset'] : 'utf8';
    //连接数据库
    $this->db_connect();
    //选择数据库
    $this->db_usedb();
    //设置字符集
    $this->db_charset();
  }
  //连接数据库
  private function db_connect(){
    $this->link=mysqli_connect($this->host,$this->user,$this->pass);
    if(!$this->link){
      echo "数据库连接失败
";
      echo "错误编码".mysqli_errno($this->link)."
";
      echo "错误信息".mysqli_error($this->link)."
";
      exit;
    }
  }
  //设置字符集
  private function db_charset(){
    mysqli_query($this->link,"set names {$this->charset}");
  }
  //选择数据库
  private function db_usedb(){
    mysqli_query($this->link,"use {$this->db}");
  }
  //私有的克隆
  private function __clone(){
    die('clone is not allowed');
  }
  //公用的静态方法
  public static function getIntance(){
    if(self::$dbcon==false){
      self::$dbcon=new self;
    }
    return self::$dbcon;
  }
  //执行sql语句的方法
  public function query($sql){
    $res=mysqli_query($this->link,$sql);
    if(!$res){
      echo "sql语句执行失败
";
      echo "错误编码是".mysqli_errno($this->link)."
";
      echo "错误信息是".mysqli_error($this->link)."
";
    }
    return $res;
  }
  //打印数据
  public function p($arr){
    echo "
";
    print_r($arr);
    echo "
";
  }
  public function v($arr){
    echo "
";
    var_dump($arr);
    echo "
";
  }
  //获得最后一条记录id
  public function getInsertid(){
    return mysqli_insert_id($this->link);
  }
  
  public function getOne($sql){
    $query=$this->query($sql);
    return mysqli_free_result($query);
  }
  //获取一行记录,return array 一维数组
  public function getRow($sql,$type="assoc"){
    $query=$this->query($sql);
    if(!in_array($type,array("assoc",'array',"row"))){
      die("mysqli_query error");
    }
    $funcname="mysqli_fetch_".$type;
    return $funcname($query);
  }
  //获取一条记录,前置条件通过资源获取一条记录
  public function getFormSource($query,$type="assoc"){
    if(!in_array($type,array("assoc","array","row")))
    {
      die("mysqli_query error");
    }
    $funcname="mysqli_fetch_".$type;
    return $funcname($query);
  }
  //获取多条数据，二维数组
  public function getAll($sql){
    $query=$this->query($sql);
    $list=array();
    while ($r=$this->getFormSource($query,"row")) {
      $list[]=$r;
    }
    return $list;
  }
  
  public function insert($table,$data){
    //遍历数组，得到每一个字段和字段的值
    $key_str='';
    $v_str='';
    foreach($data as $key=>$v){
      if(empty($v)){
 die("error");
      }
      //$key的值是每一个字段s一个字段所对应的值
      $key_str.=$key.',';
      $v_str.="'$v',";
    }
    $key_str=trim($key_str,',');
    $v_str=trim($v_str,',');
    //判断数据是否为空
    $sql="insert into $table ($key_str) values ($v_str)";
    $this->query($sql);
    //返回上一次增加操做产生ID值
    return $this->getInsertid();
  }
  
  public function deleteOne($table, $where){
    if(is_array($where)){
      foreach ($where as $key => $val) {
 $condition = $key.'='.$val;
      }
    } else {
      $condition = $where;
    }
    $sql = "delete from $table where $condition";
    $this->query($sql);
    //返回受影响的行数
    return mysqli_affected_rows($this->link);
  }
  
  public function deleteAll($table, $where){
    if(is_array($where)){
      foreach ($where as $key => $val) {
 if(is_array($val)){
   $condition = $key.' in ('.implode(',', $val) .')';
 } else {
   $condition = $key. '=' .$val;
 }
      }
    } else {
      $condition = $where;
    }
    $sql = "delete from $table where $condition";
    $this->query($sql);
    //返回受影响的行数
    return mysqli_affected_rows($this->link);
  }
  
  public function update($table,$data,$where){
    //遍历数组，得到每一个字段和字段的值
    $str='';
    foreach($data as $key=>$v){
      $str.="$key='$v',";
    }
    $str=rtrim($str,',');
    //修改SQL语句
    $sql="update $table set $str where $where";
    $this->query($sql);
    //返回受影响的行数
    return mysqli_affected_rows($this->link);
  }
  
  public function getAllData($sql){
    if (mysqli_multi_query($this->link,$sql)) {
      do {
 if ($result = mysqli_store_result($this->link)) {
   while ($row = mysqli_fetch_assoc($result)) {
     $list[] = $row;
   }
   
   mysqli_free_result($result);
 }else{
   return false;
 }
 
      } while (mysqli_next_result($this->link) && mysqli_more_results($this->link));
    } else {
      return false;
    }
    return $list;
  }
}
?>

2、存储过程调用扩展类库：

mysqli = new mysqli($config);
  }
  
  private function getRealSql($sql, array $bind = [])
  {
    foreach ($bind as $key => $val) {
      $value = is_array($val) ? $val[0] : $val;
      $value = is_string($val) ? "'{$val}'" : $val;
      // 判断占位符
      $sql = is_numeric($key) ?
 substr_replace($sql, $value, strpos($sql, '?'), 1) :
 str_replace(
   [':' . $key . ')', ':' . $key . ',', ':' . $key . ' '],
   [$value . ')', $value . ',', $value . ' '],
   $sql . ' ');
    }
    return rtrim($sql);
  }
  
  protected function procs(){
    $procedure = in_array(strtolower(substr(trim($this->sql), 0, 4)), ['call', 'exec']);
    // 参数绑定
    if ($procedure) {
      $sql = $this->getRealSql($this->sql,$this->data);
      return $this->mysqli->getAllData($sql);
    }
    return false;
  }
  
  public function data($data = [])
  {
    $this->data = $data;
    return $this;
  }
  
  public function sql($sql = '')
  {
    $this->sql = $sql;
    return $this;
  }
  
  public function demo(){
    return $this->sql("call demo(?,?,?,?,?,?)")->procs();
  }
}
?>

3、最终项目中使用demo：

use storedprocs;

 $this->procs = new procs("mysqli");

//$data为给存储过程占位符传递的参数必须为array|[ ]
$this->procs->data($data)->demo();

ok是不是调用很简单、多条存储过程的数据集就此拿到！
