PHP transmission session curl function Detailed explanation of the example
Preface:
Taking over the heavy responsibility of the person in charge of the PC side of the company's project, the responsibility is heavy; from demand analysis, drawing flow charts and building tables, Coding, testing, bug fixing, and online maintenance were all completed by myself as a polished commander (of course, I also had a front-end team with good skills, thanks to my supervisor for his help). Although it was tiring and I had to work a lot of overtime, I felt it was okay. The company was all the same. .
Not much to say, because projects often need to call the Java interface. Since the request interface is involved, there is the http request method. The common ones in PHP are GET/POST. Of course, there are other methods such as put, etc. GET/POST/PUT/DELETE are often used in Java. Of course, the request interface requires the use of curl-related functions. I hope everyone will read the documentation for debugging. The following are the related functions I have encapsulated (generally summarized, adjusted):
Sample code:
private $serverhost = "https://demo.php.cn"; //测试 /** * 请求接口封装 get/post/put/delete等 * access public * @param string $url 接口地址 * @param string $params 参数 * @param string $type 类型 get/post/put/delete * @return bool/array */ public function getcurldata($url,$params,$type="get"){ $url = $this->serverhost.$url; $response = array(); if($type == 'get'){ //get请求 //请求头可以加其他设置 $headers = array( 'Content-type: application/json;charset=UTF-8', ); $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, $url); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); curl_setopt($ch, CURLOPT_FOLLOWLOCATION, TRUE); curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0); curl_setopt($ch, CURLOPT_HTTPHEADER, $headers); $response = curl_exec($ch); }elseif ($type == 'post'){ //post请求 $headers = array( 'Content-type: application/json;charset=UTF-8', ); $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, $url); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); curl_setopt($ch, CURLOPT_FOLLOWLOCATION, TRUE); curl_setopt($ch, CURLOPT_POST, true); //注意这几行 curl_setopt($ch, CURLOPT_POSTFIELDS, $params); //注意这几行 //curl_setopt($ch, CURLOPT_HEADER, true); curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0); curl_setopt($ch, CURLOPT_HTTPHEADER, $headers); $response = curl_exec($ch); }elseif ($type == 'put'){ //put请求 $headers = array( 'Content-type: application/json;charset=UTF-8', ); $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, $url); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); curl_setopt($ch, CURLOPT_FOLLOWLOCATION, TRUE); curl_setopt($ch, CURLOPT_PUT, true); //注意这几行 curl_setopt($ch, CURLOPT_POSTFIELDS, $params); //curl_setopt($ch, CURLOPT_HEADER, true); curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0); curl_setopt($ch, CURLOPT_HTTPHEADER, $headers); $response = curl_exec($ch); } return $response; } //如何调用上面代码 //get方式 /** * 查询我创建过的班级 * @param string $url 接口地址 * @param string $params 参数 * @param string $type 类型 get * @return array */ public function mycreateclass($userid){ $url = "/xxx/xxxx/xxxx/".$userid; //请求地址拼接 $response = $this->getcurldata($url,array(),"get"); $createdclass = json_decode($response, true); //返回json格式数据 return $createdclass; } /** post方式请求 * 用户登录判断 * access public * @param string $username 用户名 * @param string $password 密码 * @return bool */ public function getlogin($username,$password) { //要post的数据 $params = array( "username" => $username, "password" => $password ); $params = json_encode($params, 64|256); $uri = "/xxx/xxx/login"; $response = $this->getcurldata($uri,$params,"post"); $result = json_decode($response, true); return $result ; } /*身份转换--put 请求 */ public function changeuserole($token){ //要put的数据 $params = array(); $params = json_encode($params, 64|256); $uri = "/xxx/xxx/xxx/".$token."/"; $response = $this->getcurldata($uri,$params,"put"); $result = json_decode($response, true); //dump($result);die; return $result; } //还有一个delete方式 大家自己参考文档调试下吧 上面3个请求方式都是单次请求(即请求一次)*************** PHP自带函数curl_multi_get_contents函数(thinkphp自带此函数,可以微调下): /** * 批量发起请求 已调通 * curl multi POST数据 * */ public function curl_multi_get_contents($url=array(), $param = array(), $timeout=1000){ $userAgent = 'Mozilla/4.0+(compatible;+MSIE+6.0;+Windows+NT+5.1;+SV1)'; $headers = array( 'Content-type: application/json;charset=UTF-8', ); $curl_array=array(); $mh = curl_multi_init(); foreach($url as $uk=>$uv){ $curl_array[$uk] = curl_init(); } unset($uk,$uv); foreach($url as $uk=>$uv) { $options = array( CURLOPT_URL => $uv, CURLOPT_TIMEOUT => $timeout, CURLOPT_RETURNTRANSFER => true, CURLOPT_DNS_CACHE_TIMEOUT => 86400, CURLOPT_DNS_USE_GLOBAL_CACHE => true, CURLOPT_SSL_VERIFYPEER => 0, CURLOPT_HEADER => false, CURLOPT_USERAGENT => 'Mozilla/4.0 (compatible; MSIE 5.01; Windows NT 5.0)', CURLOPT_HTTPHEADER => $headers, ); if (isset($param[$uk])) { foreach ($param[$uk] as $_k => $_v) { //$options[$_k] = $_v; $optionsparam[$_k] = $_v; $options[CURLOPT_POSTFIELDS] = json_encode($optionsparam, 64|256); } } curl_setopt_array($curl_array[$uk], $options); curl_multi_add_handle($mh, $curl_array[$uk]); unset($options); } unset($uk,$uv); $running = NULL; do { curl_multi_exec($mh,$running); } while($running > 0); $res = array(); foreach($url as $uk=>$uv){ $res[$uk] = curl_multi_getcontent($curl_array[$uk]); } unset($uk,$uv); foreach($url as $uk=>$uv){ curl_multi_remove_handle($mh, $curl_array[$uk]); } unset($url,$curl_array,$uk,$uv); curl_multi_close($mh); return $res; } //如何调用--批量发起请求 //批量请求加入班级 public function batchjoinclass($token,$batchjoinclass){ $urlarr = $param = $returndata = array(); $param = $batchjoinclass; //二维数组 格式如下 /* $param[1]['name'] = '班级新1'; $param[1]['iamge'] = 'xxx11.png'; $param[1]['iamgeType'] = 'CUSTOM'; $param[2]['name'] = '班级新2'; $param[2]['iamge'] = 'xxx.png'; $param[2]['iamgeType'] = 'CUSTOM'; */ //获取请求url foreach($batchjoinclass as $key=>$val){ $urlarr[$key] = $this->serverhost."/xxx/xxxx/xxxx/".$token; } $res = $this->curl_multi_get_contents($urlarr,$param); //格式化返回数据 foreach($res as $key=>$val){ $returndata[$key] = json_decode($val,true); } return $returndata; }

Arrays can be stored in PHP sessions. 1. Start the session and use session_start(). 2. Create an array and store it in $_SESSION. 3. Retrieve the array through $_SESSION. 4. Optimize session data to improve performance.

PHP session garbage collection is triggered through a probability mechanism to clean up expired session data. 1) Set the trigger probability and session life cycle in the configuration file; 2) You can use cron tasks to optimize high-load applications; 3) You need to balance the garbage collection frequency and performance to avoid data loss.

Tracking user session activities in PHP is implemented through session management. 1) Use session_start() to start the session. 2) Store and access data through the $_SESSION array. 3) Call session_destroy() to end the session. Session tracking is used for user behavior analysis, security monitoring, and performance optimization.

Using databases to store PHP session data can improve performance and scalability. 1) Configure MySQL to store session data: Set up the session processor in php.ini or PHP code. 2) Implement custom session processor: define open, close, read, write and other functions to interact with the database. 3) Optimization and best practices: Use indexing, caching, data compression and distributed storage to improve performance.

In PHP, iterating through session data can be achieved through the following steps: 1. Start the session using session_start(). 2. Iterate through foreach loop through all key-value pairs in the $_SESSION array. 3. When processing complex data structures, use is_array() or is_object() functions and use print_r() to output detailed information. 4. When optimizing traversal, paging can be used to avoid processing large amounts of data at one time. This will help you manage and use PHP session data more efficiently in your actual project.

The session realizes user authentication through the server-side state management mechanism. 1) Session creation and generation of unique IDs, 2) IDs are passed through cookies, 3) Server stores and accesses session data through IDs, 4) User authentication and status management are realized, improving application security and user experience.

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),
