复制代码 代码如下:
function getTagStyle(){
$minFontSize=8; //最小字体大小,可根据需要自行更改
$maxFontSize=18; //最大字体大小,可根据需要自行更改
return 'font-size:'.($minFontSize+lcg_value()*(abs($maxFontSize-$minFontSize))).'px;color:#'.dechex(rand(0,255)).dechex(rand(0,196)).dechex(rand(0,255));
}

此函数的作用是输出随机的样式,包括font-size和color。

如果你想指定只显示几个字体大小,而不是完全随机,请将上面的函数代码修改为:

复制代码 代码如下:
function getTagStyle(){
$sizearray = array('8','9','10','11','12','20'); //自定义字体大小,可根据需要自行修改
return 'font-size:'.$sizearray[rand(0,count($sizearray))].'pt;color:#'.dechex(rand(0,255)).dechex(rand(0,196)).dechex(rand(0,255));
}
