This article describes the PHP implementation of the color hex value converted to RGB method. Share to everyone for your reference, specific as follows:

function Hex2rgb ($colour) { 
    if ($colour [0] = = ' # ') { 
        $colour = substr ($colour, 1); 
    if (strlen ($colour) = = 6) { 
        list ($r, $g, $b) = Array ($colour [0]. $colour [1], $colour [2]. $colour [3], $colour [ 4]. $colour [5]); 
    } ElseIf (strlen ($colour) = = 3) { 
        list ($r, $g, $b) = Array ($colour [0]. $colour [0], $colour [1]. $colour [1], $col OUR[2]. $colour [2]); 
    } else {return 
    $r = Hexdec ($r); 
    $g = Hexdec ($g); 
    $b = Hexdec ($b); 
    Return array (' Red ' => $r, ' green ' => $g, ' Blue ' => $b); 
Var_dump (Hex2rgb ("#eeeeee"));

The results of the operation are as follows:

Array (3) {
 int (238)
 int (238)
 int (238)
