Question

I’m using fpdf library to generate some pdf files with php. At this moment I’m lost, because i can’t set the background color.

So, I have to use the SetColor(int r, int g, int b) function and I wish to send the values of RGB as a variable.

Using SetColor($my_color) in which $my_color = "233, 155, 123" is not the right choose.
How can I send a color variable to SetFillColor function?

Answer 1

You could use explode on $my_color and then convert each element to an integer.

$rgb = explode(', ', $my_color);
SetColor(intval($rgb[0]), intval($rgb[1]), intval($rgb[2]))
