Create Invisible Gif automatically 1

[jerijeri]

I need to have PHP generate an invisible gif and output it.

I know I can have my program read an invisible gif and output it. That's normally what I do. For this application it's not suitable.

In Perl I did this by:

print "Content-type: image/gif\n\n", pack "H*", "47494638396101000100800000ffffff" . "00000021f90401000000002c00000000" . "010001000002024401003b";


I need to do the same type of thing in PHP.

Thanks.

PHP has a pack() function, too. (

http://us3.php.net/pack)

I recommend you try:

print "Content-type: image/gif\n\n";
print pack ("H*", "47494638396101000100800000ffffff" . "00000021f90401000000002c00000000" . "010001000002024401003b"

Thank you. I didn't realize PHP had this function. I will try it out.
