If a message as ANY attachements, $struct->bytes ALWAYS = 0. To get the size of the primary body, you have to call structure->part[0]->bytes. To get the size of the whole message, either strlen(imap_body) or add up the ->bytes of all the parts.
Another interesting note:
When there is body text and no attachements:
count($struct->parts) = 0
When there is body text and 1 attachement:
count($struct->parts) = 2
These imap functions could really use better documentation. Like giving the meathods for the dparameter and parameter classes...chrislhill at "O_o" hotmail dot com ¶

print_r($struct);
Will give you a better example for your messages but they are called as $struct using the varible method above.
$struct->type; //would return the type
$struct->encoding //would return the encoding
and etc..
This can be done many different ways but that is the basics on pulling the info out of the structure of fetchstructure itself, I hope it helps someone starting because it wouldve helped me :/.sirber at detritus dot qc dot ca ¶

Another comment to inform people about something that should really be in the function description:
imap_fetchstructure() downloads the entire email, attachments and all, rather than just the structure.
I guess it's an undocumented feature, not a bug.
I had assumed that the script would have only downloaded the amount of data that was returned, but my script downloaded a cumulative 2.5gig before i noticed. Hopefully no-one else will have this happen.6 years ago
If you have errors with wrong attachment names like this:
correct name:
String -> Prüfbericht Hersteller.pdf
fetchstructure object name:
=?ISO-8859-1?Q?Pr=FCfbericht_Hersteller=2Epdf?=
Workaround to reconvert:
imap_mime_header_decode($fetchstructure->dparameters->value)[0]->text

If you logic based on compare structure strings, you must compare it case insensetive.

An update on the note from david at hundsness dot com ¶. I have used his contribution with great success, just a couple of issues. The syntax used for some string concatenations was in the form <span class="katex"><span class="katex-mathml"><math xmlns="http://www.w3.org/1998/Math/MathML"><semantics><mrow><mi>v</mi><mi>a</mi><mi>r</mi><mi mathvariant="normal">.</mi><mo>=</mo></mrow><annotation encoding="application/x-tex">var. = </annotation></semantics></math></span><span class="katex-html" aria-hidden="true"><span class="base"><span class="strut" style="height:0.4306em;"></span><span class="mord mathnormal" style="margin-right:0.03588em;">v</span><span class="mord mathnormal">a</span><span class="mord mathnormal" style="margin-right:0.02778em;">r</span><span class="mord">.</span><span class="mspace" style="margin-right:0.2778em;"></span><span class="mrel">=</span></span></span></span>var2, but should be <span class="katex"><span class="katex-mathml"><math xmlns="http://www.w3.org/1998/Math/MathML"><semantics><mrow><mi>v</mi><mi>a</mi><mi>r</mi><mi mathvariant="normal">.</mi><mo>=</mo></mrow><annotation encoding="application/x-tex">var .= </annotation></semantics></math></span><span class="katex-html" aria-hidden="true"><span class="base"><span class="strut" style="height:0.4306em;"></span><span class="mord mathnormal" style="margin-right:0.03588em;">v</span><span class="mord mathnormal">a</span><span class="mord mathnormal" style="margin-right:0.02778em;">r</span><span class="mord">.</span><span class="mspace" style="margin-right:0.2778em;"></span><span class="mrel">=</span></span></span></span>var2. I also had to add some checks for the existence of some properties, especially the structure dparameters and the keys filename and name in the parameters property. But the code has been a huge help.
