用pdo连接oracle数据库后,获取多条文章数据,返回值中包含Resource id,这些内容要怎样获取呢?

<code>$data_f = $ocl->query($sql);
print_r($data = $data_f->fetchAll(PDO::FETCH_ASSOC));
</code>
Copy after login
Copy after login

尝试这样,但获取到的都是最后一条数据的内容

<code>foreach($data as $v){
    echo stream_get_contents($v['CONTENT']);
}
</code>
Copy after login
Copy after login

而用不用fetchAll改用fetch,获取的条数倒有问题,例如sql语句中取10条,才输出3条

<code>while($v = $data_f->fetch(PDO::FETCH_ASSOC)){
    echo stream_get_contents($v['CONTENT']);
}
</code>
Copy after login

  1. 获取到的都是最后一条数据的内容, 这是一个已知的bug,在php上面有过讨论,无解

  2. fetch那里,是否是因为fetch只返回了一个字段 ? 我用循环fetch的时候,还算是正常的

我目前代码是:
`

<code>    while($row=$pStmt->fetch(PDO::FETCH_ASSOC)){
                $clobFields=$this->detectClob($row);
                if(count($clobFields)>0){
                    $this->retriveClobRow($row,$clobFields);
                }
                $rst[]=$row;
            }
            
    protected function retriveClobRow(&$row,$clobFields){
        if(count($clobFields)>0){
            foreach($clobFields as $colName){
                $row[$colName] =stream_get_contents($row[$colName]);
            }
        }
    }
            `</code>
Copy after login

总而言之, oracle pdo,就是个小玩具,即使这问题解决了,还有调用 存储过程时输出参数的问题绕不开。尽量避免使用 oracle pdo。
