I need to extract the body from an e-mail

code

$body = imap_fetchbody($this->stream, $this->msgno, $section);

But the output contains some strange chars. In the first HTML tag in the first line <div dir=3D"ltr">.. Why the 3D ??

output

<div dir=3D"ltr"><div class=3D"gmail_quote"><br><table width=3D"100%" cells=
pacing=3D"0" cellpadding=3D"0" style=3D"background:#efefef" align=3D"center=

It's quoted-printable text, probably the result of passing through a "dumb" mail client. = is used to encode/escape unprintable/metacharacters, much like &...; is used in HTML.

=3d is the quoted-printable representation of an =: 3d hex = 61 ascii = equals sign.
