深入解读PHP统计图表类
用我们通过对
Google Chart API 可以制出各种统计图表,当前支持线形图、柱形图、饼形图、散点图、曲线图。Google Charts API Code 页面有对这个 API 使用的详细说明,但是还略显繁琐。今天发现有人开发了一个这个方面的PHP统计图表类,并且还包括三个例子,我就挑选一个例子结合自己的一个项目给大家讲解下如何使用:
- ?php
- include( ’GoogChart.class.php’ );
- // 导入 Google Chart API 类
- $chart = new GoogChart();
- //实例化一个 GoogChart 对象
- $servers = get_max_servers();
- //获取 17fav.com 收藏服务排名
- $data = array(); // 初始化数据
- foreach ($servers as $server){
-
$data["$server->server_name"] = $server->
server_number/100; -
// 这里除 100是因为测试的时候发现
Chart API 不支持 >=100 的数值。 - }
- $color = array(
- ’#FF6600′,
- ’#FFB380′,
- ’#FFD9BF’,
- ’#DFBEA7′,
- ’#BF8660′,
- ’#AA6639′,
- ); //设置图像的颜色
- $chart->setChartAttrs( array(
- ’type’ => ’pie’, // 饼形图
- ’title’ => ’收藏 & 分享’, // 图像名称
- ’data’ => $data, // 图像数据
- ’size’ => array(468, 300), // 图像大小
- ’color’ => $color // 图像颜色
- ));
- echo $chart; // 输出图像
- ?>
以上就是PHP统计图表类的具体实现方法。

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,
