php Method for Generating Random Colors

In this paper, an example is given to describe the method of generating random colors in php. Share it for your reference. The specific implementation method is as follows:

function randrgb()  

{  

  $str='0123456789ABCDEF';  

    $estr='#';  

    $len=strlen($str);  

    for($i=1;$i<=6;$i++)  

    {  

        $num=rand(0,$len-1);    

        $estr=$estr.$str[$num];   

    }  

    return $estr;  

} 

I hope this article is helpful to everyone's PHP programming.
