怎么PHP算法怎么写
.we
{
border-radius: 62px; /* 所有角都使用半径为5px的圆角,此属性为CSS3标准属性 */
-moz-border-radius:62px; /* Mozilla浏览器的私有属性 */
-webkit-border-radius: 62px; /* Webkit浏览器的私有属性 */
background:#000;
width:62px; height:62px;
border-radius: 62px 62px 62px 62px; /* 四个半径值分别是左上角、右上角、右下角和左下角 */
margin-left: 15px; margin-top:15px; float: left; color: #FFF;
color: #FFF;
}

想要干嘛没说清楚啊
html5?
如果纯粹想要实现这个效果
用html5 canvas好实现
表示看不懂。。。默默流泪

我现在不是画了个圆了啊 我要做成效果图那样。。。 用算法 画上去。。怎么画。。。1个个画 到时候维护太麻烦了
求出各圆点在图中的位置
$a = rand(0, 2 * M_PI); //极角$r = rand(0, $R); //极距$x = $ox + $r * cos($a);$y = $oy + $r * sin($a);
若要保证各圆点不相交,还需另行计算两点间距离:
sqrt(pow($x1-$x2),2) + pow($y1-$y2),2)) / 2 <= 圆点半径
圆的大小和位置这些数据是怎么来的?这是关键点。

看不懂。。能帮我写下么 写成我的效果

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,
