php查询oracle返回字段读取,该如何处理

php查询oracle返回字段读取
php查询oracle数据库后，某个字段的值为：
["IJINFO"]=>
  object(OCI-Lob)#108 (1) {
  ["descriptor"]=>
  resource(117) of type (oci8 descriptor)
  }

java查询后读出的该字段内容为文本

请问这种类型的字段在php中如何读取？

------解决方案--------------------
没法读取
他是一个java对象
------解决方案--------------------
是的，这个字段里面存储的是java对象
所以用java查询后读出的该字段内容为文本

现行oracle数据库是用java写成的，所以在oracle数据库中可以存储java对象，而不需要额外的开销
------解决方案--------------------
可以读取，如：

PHP code

$arr_obj = array(["IJINFO"]=>
  object(OCI-Lob)#108 (1) {
  ["descriptor"]=>
  resource(117) of type (oci8 descriptor)
  })
$aaa = $arr_obj["IJINFO"]->descriptor;
echo "aaa-->>".$aaa."<br>";

不可以？我的是这样的：<br>

PHP code

$mine_mail = 
Array ( [1] => stdClass Object ( [headers] => Array ( [content-type] => text/plain;charset="utf-8" ) [ctype_primary] => text [ctype_secondary] => plain [ctype_parameters] => Array ( [charset] => utf-8 ) [body] => vif5f+CM/R6Ej4pA3eq7wsRbp/0Irr4GDeqB92pDvW+PSo/lPdFmSvtae4vVFzdb0p64aXra0yH8H4RhY9CScEBzJ+/GpNmzmq8x2IMNRiqannBk5mBaB8zcNA96IQ1oLbwIQLZraCip7IIo3oT1j0uZ/YspW4SSWB4NfOr+554= [mime_id] => 1 ) [2] => stdClass Object ( [headers] => Array ( [x-attach-l] => 1 [content-type] => application/msword;name="netchina_1 ReleasedBy_sean(Data_2012-2-21).doc"; [content-transfer-encoding] => base64 [content-disposition] => attachment;filename="netchina_1 ReleasedBy_sean(Data_2012-2-21).doc" ) [ctype_primary] => application [ctype_secondary] => msword [ctype_parameters] => Array ( [name] => netchina_1 ReleasedBy_sean(Data_2012-2-21).doc ) [disposition] => attachment [d_parameters] => Array ( [filename] => netchina_1 ReleasedBy_sean(Data_2012-2-21).doc ) [body] => sasds）

$body = $mine_mail[1]->body;
$encoding = $mine_mail[1]->ctype_parameters['charset'];
$filename = $mine_mail[2]->ctype_parameters['name']; <div class="clear">
                 
              
              
        
            </div>
