Description:
------------
The documentation of imagepng (in English and German) states that the
second parameter may be null or the empty string:
"
bool imagepng ( resource image [, string filename] )
The filename argument is optional, and if left off or filled with a
NULL value, the raw image stream will be output directly.
"
This is not the case, at least in php 5.1.6 this function does not work
anymore if given an empty string or null as second parameter. It will
merely generate a warning ("Unable to open '' for writing"), and output
some trash, not a real png image.
This problem is NOT related to sending a bad header.
The same code worked fine for me in php 5.0.4; after an upgrade to
5.1.6 it stopped working. I removed the second (null) parameter to
imagepng, and it worked again. Only it took a couple of hours to find
out :)
There at least 2 bug reports that are related to this, both of which
have been closed (nothing having been done about them):
