Betreff: Re: Next question about data output...<smile>
OK, seems what's causing issue is imagecreatefromstring(), since,
directly
after retrieving longblob data from database, memory usage is:
3402136 = 3.*Mb
and, then immediately after that calling:
$imgOut = imagecreatefromstring($bOut);
and, return that $imgOut variable to calling function, before do anything
else, memory usage:
44063856 - 44Mb+
And, this is on my windows development machine, so seems issue is with
operations, and not machine specific, although not sure why it's working
on
this machine, and not on production server.
Either way, think will, for now, switch image output rendering back to
simpler method that worked before, instead of using actual
mysqli_statement,
and see if works as such - might also put the memory usage 'logging' in
there, to actually compare them, or something.
Stay well
