POparsing email attachments in php
text
Body
copied!<p>I have a .forward.postix that is piping incoming emails to a shell account, and consequently to a PHP script that parses the emails - awesome.</p> <p>As of now, and based on everything I've seen online, I'm using the <code>explode('From: ', $email);</code> approach to split everything down into the vars I need for my database.</p> <p>Enter attachments! Using the same approach, I'm doing this to pull out a jpg attachment - but it appears not every email client formats the raw source the same way and it's causing some headaches!</p> <pre><code>$contentType1 = explode('Content-type: image/jpg;', $email); //start ContentType $contentType2 = explode("--Boundary_", $contentType1[1]); //end ContentType $jpg1 = explode("\n\n", $contentType2[0]); //double return starts base64 blob $jpg2 = explode("\n\n", $jpg1[1]); //double return marks end of base64 blob $image = base64_decode($jpg2[0]); //decode base64 blob into jpg raw </code></pre> <p><strong>Here's my issue:</strong> Not all mail clients - like GMail for example - list an attachment as <code>'Content-type: image/jpg'</code>. GMail puts in <code>'Content-Type: IMAGE/JPEG'</code> and sometimes sends it as <code>'Content-Type: image/jpeg'</code>! Which don't match my explode...</p> <p><strong>My Question:</strong> Does someone know a better way of finding the bounds of a base64 blob? or maybe a case-insensitive way of exploding the <code>'Content-Type:'</code> so I can then try against <code>image/jpg</code> or <code>image-jpeg</code> to see what matches?</p>
