用于显示彩虹字符串，支持UTF8和中文，效果如下：
function color_txt($str){<br>
$len = mb_strlen($str);<br>
$colorTxt = '';<br>
for($i=0; $i
$colorTxt .= '<span>'.mb_substr($str,$i,1,'utf-8').'</span>';<br>
}<br>
return $colorTxt;<br>
}<br>
function rand_color(){<br>
return '#'.sprintf("%02X",mt_rand(0,255)).sprintf("%02X",mt_rand(0,255)).sprintf("%02X",mt_rand(0,255));<br>
