如何使用imap删除php中的编码获取部分

When I fetch a particular mail using imap in php, I get some some encoded text before the fetched mail. How can I remove the encoded part..??

For eg. --001a11c129bebb60d204f687b277 Content-Type: text/plain; charset=ISO-8859-1 Sir, I would like to request you to grant me the permission to use the CSE lab number 1 for the Polaris event we are organizing from 26th September to 28th September.
