Convert hex color to RGB values in PHP

Question

What would be a good way to convert hex color values like #ffffff into the single RGB values 255 255 255 using PHP?

Answer 1

Convert Color Code HEX to RGB

$color = '#ffffff';
$hex = str_replace('#','', $color);
if(strlen($hex) == 3):
   $rgbArray['r'] = hexdec(substr($hex,0,1).substr($hex,0,1));
   $rgbArray['g'] = hexdec(substr($hex,1,1).substr($hex,1,1));
   $rgbArray['b'] = hexdec(substr($hex,2,1).substr($hex,2,1));
else:
   $rgbArray['r'] = hexdec(substr($hex,0,2));
   $rgbArray['g'] = hexdec(substr($hex,2,2));
   $rgbArray['b'] = hexdec(substr($hex,4,2));
endif;

print_r($rgbArray);

Output

Array ( [r] => 255 [g] => 255 [b] => 255 )
