Converting RGB values to HEX

[johnsliced]

<?PHP

$file_handle = fopen("colors/rgb.csv", "r");

while (!feof($file_handle) ) {

$line_of_text = fgetcsv($file_handle, 1024);

print $line_of_text[2] . $line_of_text[3] . $line_of_text[4] . "<BR>";

}

fclose($file_handle);

?>

 

my code above currently outputs a list of RGB numbers for example:

 

Ref_RRef_GRef_B

149119109

190171158

200161148

154109111

1088888

1408579

 

I would like to now convert these numbers (each line) to HEX colors

 

please help?!

 

thanks

Split it up and use dechex.

 

By the way, you've chosen a really bad format for storing it in. Take for instance this: 11211222. It could be either 11,211,222 or 112,11,222 or 112,112,22.

 

Edit: Ah, never mind. I didn't notice that it was just the way you were outputting it. In that case, just call dechex() on all of them.
