[RESOLVED] Getting multiple values from a single field value

mittra

Brief background:

I am implementing a ticket system that requires the imap c-client functions, but my hosting company doesn't have the imap extension installed, let alone enabled, so I am working around it by using Zend\Mail instead. Because I don't have the imap c-client functions available to me, I am working on workarounds and have been relatively successful so far, but because my knowledge of php is rudimentary at best it is slow going and I have a few questions.

Using Zend\Mail the field Content-Type looks like this:

Content-Type: text/html; charset=ISO-8859-1

I can determine the MIME Content-Type by using:

strtok($part->contentType, ';')

Is there an easy means for pulling out the charset from that field?

Maybe a regex match to get both at once would be appropriate.

As I noted, my knowledge of php is fairly rudimentary. What do you mean by a regex match? Could you provide an example?

FWIW - I have identified a means of determining the charset, I am asking about regex matching to further my knowledge of php in the hopes that this may answer a future question down the road.

Here's how I found charset:

$charset = $part->getHeaderField('Content-Type', 'charset');

I'm going to mark this thread as resolved since I figured out how to get the charset from the OP, but I would still be interested in more information about regex matching if you have a moment.

Here is one such way to get the charset using regex.

$str = 'Content-Type: text/html; charset=ISO-8859-1';
$pattern = '/charset=([a-z0-9-]+)/i';
if( preg_match($pattern, $str, $match) )
{
   printf('charset is %s', $match[1]);
}

Thanks, Derokorian.

Like I said, I found another solution, but that is very useful information that I may be able to use elsewhere in this script, or, more likely, in another script I am developing for a completely unrelated matter. 🙂
