方法一:
随机生成颜色值(例如 FF00FF).
color.php
复制代码 代码如下:
function random_color(){
mt_srand((double)microtime()*1000000);
$c = '';
while(strlen($c)
$c .= sprintf("%02X", mt_rand(0, 255));
}
return $c;
}
方法二:
复制代码 代码如下:
function randrgb()
{
$str='0123456789ABCDEF';
$estr='#';
$len=strlen($str);
for($i=1;$i
{
$num=rand(0,$len-1);
$estr=$estr.$str[$num];
}
return $estr;
}
方法三:
复制代码 代码如下:
function randColor(){
$colors = array();
for($i = 0;$i
$colors[] = dechex(rand(0,15));
}
return implode('',$colors);
}
使用方法如下:
随机颜色:#'.randColor().'';?>
