(PHP Extension) Iterate MIME Parts of an EmailDemonstrates how to iterate over the MIME sub-parts of an email, and retrieve the content of each MIME sub-part body. Note: This example requires some new features added to Chilkat v9.5.0.95.
<?php // The version number (9_5_0) should match version of the Chilkat extension used, omitting the micro-version number. // For example, if using Chilkat v9.5.0.48, then include as shown here: include("chilkat_9_5_0.php"); // This example assumes the Chilkat API to have been previously unlocked. // See Global Unlock Sample for sample code. // See the following Chilkat post to Quickly Understand Email MIME $email = new CkEmail(); $success = $email->LoadEml('qa_data/eml/sample.eml'); if ($success == false) { print 'Failed to load .eml' . "\n"; exit; } $sbContentType = new CkStringBuilder(); $caseSensitive = false; // Get the total number of non-multipart MIME sub-parts. // (This is a simple way of iterating over all the MIME leaf parts regardless of the MIME tree structure) $inlineOnly = false; $excludeAttachments = false; $searchSpec = '*/*'; $numParts = $email->GetNumPartsOfType($searchSpec,$inlineOnly,$excludeAttachments); $i = 0; while ($i < $numParts) { // What is the Content-Type of this MIME part? $sbContentType->Append($email->getNthContentType($i,$searchSpec,$inlineOnly,$excludeAttachments)); if ($sbContentType->StartsWith('text/',$caseSensitive) == true) { // Get the text body of this MIME part. $textBody = $email->getNthTextPartOfType($i,$searchSpec,$inlineOnly,$excludeAttachments); print 'Got text body for ' . $sbContentType->getAsString() . "\n"; } else { if ($sbContentType->ContentsEqual('message/rfc822',$caseSensitive) == true) { // If the Content-Type is message/rfc822, then the MIME body for this part contains a full embedded MIME messages. // Your application could load it into a Chilkat email object and recursively process... $attachedEmail = new CkEmail(); $bdMime = new CkBinData(); $email->GetNthBinaryPartOfTypeBd($i,$searchSpec,$inlineOnly,$excludeAttachments,$bdMime); $attachedEmail->SetFromMimeBd($bdMime); // Now your app can recursively process the attachedEmail... } else { // Get the bytes of this MIME body part. $bd = new CkBinData(); $email->GetNthBinaryPartOfTypeBd($i,$searchSpec,$inlineOnly,$excludeAttachments,$bd); print 'Got binary body for ' . $sbContentType->getAsString() . ' numBytes = ' . $bd->get_NumBytes() . "\n"; } } $sbContentType->Clear(); $i = $i + 1; } ?> |
