Homephp教程php手册php生成随机颜色方法汇总

前段时间在一个项目中,需要在同一个页面中的任意div背景颜色值,用php自动生成,也就是说每个div都产生不同的颜色

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().'';?>
