Detailed explanation of using Echarts to generate statistical reports with PHP
This article mainly introduces the implementation code of PHP using Echarts to generate data statistical reports. Friends who need it can refer to it. I hope it can help everyone.
echarts statistics, simple example
Look at the renderings first
<p class="panel panel-info"> <p class="panel-body"> <p id="echart_show" style="height:500px"></p> </p> </p>js file can refer to the official website, or download it here, introduce The following is the specific method
<script type="text/javascript"> var date = [],num = []; $(document).ready(function () { // 绘制反馈量图形 var init_echarts = function () { var refreshChart = function (show_data) { my_demo_chart = echarts.init(document.getElementById('echart_show')); my_demo_chart.showLoading({ text: '加载中...', effect: 'whirling' }); var echarts_all_option = { title: { text: '', subtext: '用户走势' }, tooltip: { trigger: 'axis' }, legend: { data: ['用户数', '用户消耗'] }, toolbox: { show: true, feature: { mark: {show: true}, dataView: {show: true, readOnly: false}, magicType: {show: true, type: ['line', 'bar']}, restore: {show: true}, saveAsImage: {show: true} // myTool2: { // show: true, // title: '自定义扩展方法', // icon: 'image://http://echarts.baidu.com/images/favicon.png', // onclick: function (){ // alert('自定义') // } // } } }, dataZoom: { show: false, start: 0, end: 100 }, xAxis: [ { type: 'category', boundaryGap: true, data: show_data[1] }, { type: 'category', boundaryGap: true, data: show_data[1] } ], yAxis: [ { type: 'value', scale: true, name: '用户数', boundaryGap: [0, 0.5] // boundaryGap: [0.2, 0.2] }, { type: 'value', scale: true, name: '用户数', boundaryGap: [0, 0.5] } ], series: [ { name: '用户消耗', type: 'bar', xAxisIndex: 1, data: show_data[0] }, { name: '用户数', type: 'line', xAxisIndex: 1, data:show_data[0] } ] }; my_demo_chart.hideLoading(); my_demo_chart.setOption(echarts_all_option); }; // 获取原始数据 $.ajax({ url:"__CONTROLLER__/getRes", async:false, dataType:'json', type:'post', success:function(msg){ var result = msg.result; if(msg.code == 200){ for(var i = 0 ; i < result.length; i++){ date.push(result[i].date); num.push(result[i].count); msg[0] = num; msg[1] = date; refreshChart(msg); } } } }); }; // 默认加载 var default_load = (function () { init_echarts(); })(); }); </script>Query the data you need in the controller (the date queried here and the corresponding quantity)
//折线统计 public function getRes(){ $user = M('account'); $sql = "SELECT date(createTime) AS date,count(*) as count FROM t_account GROUP BY date "; $result = $user->query($sql); $this->ajaxReturn(array('code'=>200,'result'=>$result)); }At this point, a simple echarts statistical chart has come outIf you don’t understand some parameters in echarts, you can refer to the official website Echarts DocumentationRelated recommendations:

Session regeneration refers to generating a new session ID and invalidating the old ID when the user performs sensitive operations in case of session fixed attacks. The implementation steps include: 1. Detect sensitive operations, 2. Generate new session ID, 3. Destroy old session ID, 4. Update user-side session information.

PHP sessions have a significant impact on application performance. Optimization methods include: 1. Use a database to store session data to improve response speed; 2. Reduce the use of session data and only store necessary information; 3. Use a non-blocking session processor to improve concurrency capabilities; 4. Adjust the session expiration time to balance user experience and server burden; 5. Use persistent sessions to reduce the number of data read and write times.

The security of PHP sessions can be achieved through the following measures: 1. Use session_regenerate_id() to regenerate the session ID when the user logs in or is an important operation. 2. Encrypt the transmission session ID through the HTTPS protocol. 3. Use session_save_path() to specify the secure directory to store session data and set permissions correctly.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
