[Phpgroupware-developers] Re: [Phpgroupware-users] Sending email with attachments

[Don Graver]

I am sending this to the developers b/c I think you are more able to 
help with the following technical issue.

I have run into a problem with sending emails that have large 
attachments (about 1MB+) using the class 'send'.  I am currently able to 
add attachments to an event (see below for previous discussion from 
phpgroupware-users), but when files get to the size of around 1MB, I 
either timeout or memory is exceeded.  I have upped the memory in 
php.ini to 20MB, with a timeout of 300seconds and things work fine.  
However, with only 100 seconds it timesout.  I have tracked down the 
problem to the following function in /phpgwapi/inc/class.send.inc.php:

   function put2socket($socket,$message)

It hangs in the 'do' loop b/c the file is so large.  To give you an idea 
of what the $message contains: it has the standard event notification 
message, along with the appropriate Mime headers, and the attached file 
encoded using the following: chunk_split(base64_encode($file).  I know 
my code is working b/c of being able to send multiple smaller 
attachments, as well as being able to send the larger ones by editing 
the php.ini file.  However, I don't think I should have to edit the 
php.ini file to send a file that is only 1MB.  Any thoughts of how the 
function can be optimized or how I may be able to change something?

I am using the following:
phpGW: 0.9.14.508
php: 4.2.3
apache: Apache/1.3.27 (Unix) Debian GNU/Linux

Thanks for the help.
