fetch attactments - imap_fetchbody()

Question

How to fetch attachments in an email?

code

$structure = imap_fetchstructure($this->stream, $this->msgno);
//print_r($structure);
if(isset($structure->parts)){
    foreach($structure->parts as $section => $part){
        if(isset($part->disposition)){
            if(strtolower($part->disposition) == 'attachment'){
                echo 'section = '.$section."\n";
                $body = imap_fetchbody($this->stream, $this->msgno, $section);
                
                $finfo = new finfo(FILEINFO_MIME);
                echo $finfo->buffer($body) . "\n";
                
                $file = Init::$dynamic['data_path'].$this->msgno.'_'.$part->dparameters[0]->value;
                
                imap_savebody($this->stream, $file, $this->msgno, $section);
                
                echo $finfo->file($file) . "\n";
                
                //print_r($body);
            }
        }
    }
}

the returned attachments isn't even near the correct file size and the returned data looks something like this

Identical files either has the same file size even if they are copies

Answer 1

I think your make your code complicate.

Your problem is you did not get your encode data

$body = imap_fetchbody($this->stream, $this->msgno, $part);
//$part=2 (first attachment file)
//$part=3 (second attachment file) ...

before you can get your real data in that file please take a look at

$coding = $structure->parts[$part]->encoding;
if ($coding == 0) {
    $body = imap_7bit($body);
} elseif ($coding == 1) {
    $body= imap_8bit($body);
} elseif ($coding == 2) {
    $body = imap_binary($body);
} elseif ($coding == 3) {
    $body = imap_base64($body);
} elseif ($coding == 4) {
    $body = imap_qprint($body);
} elseif ($coding == 5) {
    $body = $body;
}

so you can try to print this out :

echo $body;

Note : $section is the part of your files.
