function hex2rgb($hexColor){
$color=str_replace('#','',$hexColor);
if (strlen($color)> 3){
$rgb=array(
'r'=>hexdec(substr($color,0,2)),
'g'=>hexdec(substr($color,2,2)),
'b'=>hexdec(substr($color,4,2))
);
}else{
$color=str_replace('#','',$hexColor);
$r=substr($color,0,1). substr($color,0,1);
$g=substr($color,1,1). substr($color,1,1);
$b=substr($color,2,1). substr($color,2,1);
$rgb=array(
'r'=>hexdec($r),
'g'=>hexdec($g),
'b'=>hexdec($b)
);
}
return $rgb;
}例如：
print_r(hex2rgb('#F03'));
//输出：Array ( [r] => 255 [g] => 0 [b] => 51 )
