HomeBackend DevelopmentPHP TutorialPHP uses command line mode to collect stock trend information example code

Stock information When we make financial management websites, we only collect data from portal sites. It is impossible to generate stock information by ourselves. This will require grabbing data from stock sites. Let's take a look at an article about collecting all data from the PHP command line. Stock trend information program, details are as follows.

The main function has only one class implementation (stock.class.php):

<?php
 class StockClass{
 public $stockId;
 
 public function construct($stockId){
  $this -> stockId = $stockId;
 }
 
 private function getUrl(){
  return "http://stockpage.10jqka.com.cn/" . $this -> stockId . "/";
 }
 
 private function getPage(){
  return file_get_contents($this -> getUrl());
 }
 
 //核心,通过正则匹配出 标签名,并将对应的方法的结果替换掉标签占位符
 public function getInfo($template){
  $html = $this -> getPage();
  if( preg_match_all("/\{([^\}]*)\}/", $template, $result) ){
  foreach($result[1] as $index => $fun){
   $template = str_replace($result[0][$index], $this -> $fun($html), $template);
  }
  }
  return mb_convert_encoding($template, "GBK", "UTF-8"); //Windows的命令提示符编码是GBK
 }
 
 private function match($pattern, $html, $itemIndex = 1){
  $pattern = &#39;/&#39; . str_replace(&#39;/&#39;, &#39;\/&#39;, $pattern) . &#39;/&#39;;
  if( preg_match($pattern, $html, $result) ){
  return $result[$itemIndex];
  }else{
  return "-";
  }
 }
 
 //趋势的规则都一样,合并
 private function qushiPattern($name){
  return &#39;<p class="txt-aside">&#39; . $name . &#39;:</p>\s*<p class="txt-main">([^<]*)</p>&#39;;
 }
 
 //支持的标签
 private function name($html){
  return $this -> match("<title>([^\(<]*)\(", $html, 1);
 }
 private function score($html){
  return $this -> match(&#39;<span class="analyze-num">(\d+(\.\d+)?)</span>&#39;, $html);
 }
 private function tips($html){
  return $this -> match(&#39;<span class="analyze-tips">([^<]*)</span>&#39;, $html);
 }
 private function qushishort($html){
  return $this -> match($this -> qushiPattern("短期趋势"), $html);
 }
 private function qushimiddle($html){
  return $this -> match($this -> qushiPattern("中期趋势"), $html);
 }
 private function qushilong($html){
  return $this -> match($this -> qushiPattern("长期趋势"), $html);
 }
 }
?>

The calling method in the command prompt is as follows (stock.php):

<?php
 
 if(count($argv) >= 2){
 require("stock.class.php");
 $stockId = $argv[1];
 $stock = new StockClass($stockId);
 $temp = $stockId;
 $temp .= " {name}"; //名称
 $temp .= " {score}"; //评分
 $temp .= " {tips}"; //描述
 $temp .= " {qushishort}"; //短期趋势
 $temp .= " {qushimiddle}"; //中期趋势
 $temp .= " {qushilong}"; //长期趋势
 //$temp .= " {zidingyi}"; //自定义,直接在StockClass增加zidingyi方法即可
 $temp .= "\n";
 echo $stock -> getInfo($temp);
 }
?>


Use directly *\php.exe stock.php The stock code can be called. If the input is too long each time, you can Simplify with batch processing.

Save the following code as stock.cmd.

@XXX\php.exe stock.php %1

How can you check if a PHP session has already started?How can you check if a PHP session has already started?Apr 30, 2025 am 12:20 AM

In PHP, you can use session_status() or session_id() to check whether the session has started. 1) Use the session_status() function. If PHP_SESSION_ACTIVE is returned, the session has been started. 2) Use the session_id() function, if a non-empty string is returned, the session has been started. Both methods can effectively check the session state, and choosing which method to use depends on the PHP version and personal preferences.

Alternatives to PHP sessions include Cookies, Token-based Authentication, Database-based Sessions, and Redis/Memcached. 1.Cookies manage sessions by storing data on the client, which is simple but low in security. 2.Token-based Authentication uses tokens to verify users, which is highly secure but requires additional logic. 3.Database-basedSessions stores data in the database, which has good scalability but may affect performance. 4. Redis/Memcached uses distributed cache to improve performance and scalability, but requires additional matching
