I get sometimes (with zend_pdf) the folowing error:
Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 1572864 bytes)

Is the temporary streams (php://temp) a way to fix this? Does anybody know if it’s possible for zend_pdf to use a tempfile instead of memory?

Ah, this post got me thinking about it again and discovered how to get compression filters working.
Have to remove the filter from the stream before try and read the compressed contents.

I’ve been using the temporary streams for a while now and particularly for testing like you pointed out, but I found something a little strange when doing so. I found that you could open php://memory in read only mode, but still are able to write to it, which scuppered some testing I was doing on my own logging class. I reported a bug, but nobody seemed interested, probably as it’s a strange use-case.

I’ve tried to use the memory streams in the past, together with the compression filters. But sadly it doesn’t work.

Think the compression filters require the fclose() to finalise things, by which point you’ve lost the memory stream.

We used interfax.net. It provides a SOAP-based web service where you can send documents for faxing and then later poll their transmission status. We built a queue to manage this that can be seen in the screenshots and video on this page.

Interesting read. Could you tell a bit more about this fax integration? Do you simply send a pdf file to the machine on a network? And if so, what tools you’re using for that (some native OS commands or pure php?)? Thanks
