[PHP] output buffering / output compression

[Paul Birnstihl]

I have recently set up a machine with PHP with both buffering and 
compression turned on. Some of the pages being served include up to 3MB 
of HTML.


Can someone explain the benefit(s) of setting these ini directives to 
values (ie. larger than 4kb) rather than On ?


I've played around with it as I thought it might speed things up by 
using a bigger buffer etc. but the only difference I noticed is a big 
jump in memory usage.


Thanks!

[PHP] Re: Hidden Images.

If you have a 2bit GIF with only white and transparent and you place it 
on a white page (background), you can hide it until it's highlit. Not 
very pretty but it works.

I've been figuring out how to create hidden images.  The concept is: when 
you highlight an image in Internet Explorer (and Mozilla too, though the 
grid is reversed) it puts a grid over the image.  If you put another image 
in between what the grid covers, you can kind of hide the image that then is 
exposed when highlighted in Internet Explorer.  You can check out a kinda of 
crappy first experiment at:

I'm guessing it would be xsize x ysize x colour depth = size in bits ?

What's the default color depth?

It looks to me like it's 8bit for imagecreate and maybe 24bit for 
imagecreatetruecolor ? Does anyone else know about this for certain ?

Not sure why the I am still getting the tags and spaces after the call to
htmlentities().
Check out the source code of the output. Maybe you want the strip_tags() 
function ?

[PHP] Re: POST superglobal is empty

[Paul Birnstihl]

Might be a dumb idea but have you tried putting method=POST instead of 
method=post ?
