PHP read EML instance, PHP parsing eml, eml parsing into web pages

PHP reads the EML instance, this example resolves the exported eml file to the body, and can save the attachment to the server. Do not say more directly paste code.

If you think this code is good, please click on the praise. Thank you ~ ~ ~
