利用php函數將16禁止的顏色代碼轉換為RGB色值。
/** * function 16進制顏色轉換為RGB色值 * author www.phpernote.com */ 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')); //輸出:Array ( [r] => 255 [g] => 0 [b] => 51 )
