PHP实现基于PDO扩展连接PostgreSQL对象关系数据库示例

时间:2019-10-14 13:35     来源/作者:_jan_

本文实例讲述了PHP实现基于PDO扩展连接PostgreSQL对象关系数据库的方法。分享给大家供大家参考,具体如下:

$pdo = NULL;
if(version_compare(PHP_VERSION, '5.3.6', '<')){
  $pdo = new \PDO('pgsql:host=127.0.0.1;port=5432;dbname=postgredb1','postgres',"123456",array(\PDO::MYSQL_ATTR_INIT_COMMAND=>'SET NAMES \'UTF8\'' ));
}
else{
  $pdo = new \PDO('pgsql:host=127.0.0.1;port=5432;dbname=postgredb1','postgres',"123456");
}
try {
  $pdo->beginTransaction();
  $tableName = 'user';
  if($fetch = true){
    $myPDOStatement = $pdo->prepare("SELECT * FROM " . $tableName . " WHERE id=:id ");
    if(!$myPDOStatement) {
      $errorInfo = $myPDOStatement->errorInfo();
      throw new \Exception($errorInfo[0].'###'.$errorInfo[1].'###'.$errorInfo[2]);
    }
    $id = 1;
    $myPDOStatement->bindParam(":id",$id);
    $myPDOStatement->execute();
    if($myPDOStatement->errorCode()>0){
      $errorInfo = $myPDOStatement->errorInfo();
      throw new \Exception($errorInfo[0].'###'.$errorInfo[1].'###'.$errorInfo[2]);
    }
    $item = $myPDOStatement->fetch();
    print_r($item);
  }
  $insertedId = 0;
  if($insert = true){
    $myPDOStatement = $pdo->prepare("INSERT INTO " . $tableName . "(username,password,status)  VALUES(:username,:password,:status)");
    if(!$myPDOStatement) {
      $errorInfo = $myPDOStatement->errorInfo();
      throw new \Exception($errorInfo[0].'###'.$errorInfo[1].'###'.$errorInfo[2]);
    }
    $timestamp = time();
    $data = array(
      'username' =>'usernamex',
      'password' =>'passwordx',
      'status' =>'1',
    );
    $myPDOStatement->bindParam(":username",$data['username']);
    $myPDOStatement->bindParam(":password",$data['password']);
    $myPDOStatement->bindParam(":status",$data['status']);
    $myPDOStatement->execute();
    if($myPDOStatement->errorCode()>0){
      $errorInfo = $myPDOStatement->errorInfo();
      throw new \Exception($errorInfo[0].'###'.$errorInfo[1].'###'.$errorInfo[2]);
    }
    $affectRowCount = $myPDOStatement->rowCount();
    if($affectRowCount>0){
      $insertedId = $pdo->lastInsertId();
    }
    print_r('$insertedId = '.$insertedId);//PostgreSQL不支持
    print_r('$affectRowCount = '.$affectRowCount);
  }
  if($update = true){
    $myPDOStatement = $pdo->prepare("UPDATE " . $tableName . " SET username=:username, status=:status WHERE id=:id");
    if(!$myPDOStatement) {
      $errorInfo = $myPDOStatement->errorInfo();
      throw new \Exception($errorInfo[0].'###'.$errorInfo[1].'###'.$errorInfo[2]);
    }
    $id = 1;
    $username = 'username update';
    $status = 0;
    $myPDOStatement->bindParam(":id",$id);
    $myPDOStatement->bindParam(":username",$username);
    $myPDOStatement->bindParam(":status",$status);
    $myPDOStatement->execute();
    if($myPDOStatement->errorCode()>0){
      $errorInfo = $myPDOStatement->errorInfo();
      throw new \Exception($errorInfo[0].'###'.$errorInfo[1].'###'.$errorInfo[2]);
    }
    $affectRowCount = $myPDOStatement->rowCount();
    print_r('$affectRowCount = '.$affectRowCount);
  }
  if($fetchAll = true){
    $myPDOStatement = $pdo->prepare("SELECT * FROM " . $tableName ." WHERE id > :id");
    if(!$myPDOStatement) {
      $errorInfo = $myPDOStatement->errorInfo();
      throw new \Exception($errorInfo[0].'###'.$errorInfo[1].'###'.$errorInfo[2]);
    }
    $id = 0;
    $myPDOStatement->bindParam(":id",$id);
    $myPDOStatement->execute();
    if($myPDOStatement->errorCode()>0){
      $errorInfo = $myPDOStatement->errorInfo();
      throw new \Exception($errorInfo[0].'###'.$errorInfo[1].'###'.$errorInfo[2]);
    }
    $list = $myPDOStatement->fetchAll();
    print_r($list);
  }
  if($update = true){
    $myPDOStatement = $pdo->prepare("DELETE FROM " . $tableName . " WHERE id=:id");
    if(!$myPDOStatement) {
      $errorInfo = $myPDOStatement->errorInfo();
      throw new \Exception($errorInfo[0].'###'.$errorInfo[1].'###'.$errorInfo[2]);
    }
    //$insertedId = 10;
    $myPDOStatement->bindParam(":id",$insertedId);
    $myPDOStatement->execute();
    if($myPDOStatement->errorCode()>0){
      $errorInfo = $myPDOStatement->errorInfo();
      throw new \Exception($errorInfo[0].'###'.$errorInfo[1].'###'.$errorInfo[2]);
    }
    $affectRowCount = $myPDOStatement->rowCount();
    print_r('$affectRowCount = '.$affectRowCount);
  }
  $pdo->commit();
} catch (\Exception $e) {
  $pdo->rollBack();
//     print_r($e);
}
$pdo = null;

希望本文所述对大家PHP程序设计有所帮助。
