利用php函数将16禁止的颜色代码转换为RGB色值。
/** * function 16进制颜色转换为RGB色值 */ 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; }
例子
print_r(hex2rgb('#F03')); //输出:Array ( [r] => 255 [g] => 0 [b] => 51 )
