php查询oracle返回字段读取,该如何处理

$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>";
<br><font color="#e78608">------解决方案--------------------</font><br>
不可以？我的是这样的：<br><dl class="code">PHP code<pre class="brush:php;toolbar:false layui-box layui-code-view layui-code-notepad"><ol class="layui-code-ol"><li></li><li>$mine_mail = </li><li>Array ( [1] => stdClass Object ( [headers] => Array ( [content-type] => text/plain;charset="utf-8" ) [ctype_primary] => text [ctype_secondary] => plain [ctype_parameters] => Array ( [charset] => utf-8 ) [body] => vif5f+CM/R6Ej4pA3eq7wsRbp/0Irr4GDeqB92pDvW+PSo/lPdFmSvtae4vVFzdb0p64aXra0yH8H4RhY9CScEBzJ+/GpNmzmq8x2IMNRiqannBk5mBaB8zcNA96IQ1oLbwIQLZraCip7IIo3oT1j0uZ/YspW4SSWB4NfOr+554= [mime_id] => 1 ) [2] => stdClass Object ( [headers] => Array ( [x-attach-l] => 1 [content-type] => application/msword;name="netchina_1 ReleasedBy_sean(Data_2012-2-21).doc"; [content-transfer-encoding] => base64 [content-disposition] => attachment;filename="netchina_1 ReleasedBy_sean(Data_2012-2-21).doc" ) [ctype_primary] => application [ctype_secondary] => msword [ctype_parameters] => Array ( [name] => netchina_1 ReleasedBy_sean(Data_2012-2-21).doc ) [disposition] => attachment [d_parameters] => Array ( [filename] => netchina_1 ReleasedBy_sean(Data_2012-2-21).doc ) [body] => sasds）</li><li>$body = $mine_mail[1]->body;</li><li>$encoding = $mine_mail[1]->ctype_parameters['charset'];</li><li>$filename = $mine_mail[2]->ctype_parameters['name'];                     </li></ol></pre></dl>
