PHP GD and system()

phpnewb72 · 06-01-2007, 02:47 PM

Is there a way to intergrate something like system("uname -r"); into an gd created image?

I was hoping something like this would work:

$im=imagecreate(300,400);
$white=imagecolorallocate($im,255,255,255);
$black=imagecolorallocate($im,0,0,0);

imagestring($im,6,5,10,system("uname -r"),$white);

Hi

The only problem I can think of is that system outputs the results of the command - and it returns the last line of the output, so your code should work, but you can't output the image after you have started outputting text.

So better change the "system" into "exec" or "popen" so you can get the result in a string first without any output.

nice, thanks. exec() works much better.

cheers!
