Using PHP command line mode to collect stock trend information_php example
Without further ado, let’s look directly at the implementation code.
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 = '/' . str_replace('/', '\/', $pattern) . '/'; if( preg_match($pattern, $html, $result) ){ return $result[$itemIndex]; }else{ return "-"; } } //趋势的规则都一样,合并 private function qushiPattern($name){ return '<div class="txt-aside">' . $name . ':</div>\s*<div class="txt-main">([^<]*)</div>'; } //支持的标签 private function name($html){ return $this -> match("<title>([^\(<]*)\(", $html, 1); } private function score($html){ return $this -> match('<span class="analyze-num">(\d+(\.\d+)?)</span>', $html); } private function tips($html){ return $this -> match('<span class="analyze-tips">([^<]*)</span>', $html); } private function qushishort($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, batch processing can be used to simplify it.
Save the code below as stock.cmd.
@XXX\php.exe stock.php %1
Run result:
This completes the collection of individual stock trends. If you want to collect all stock information, you can save it as a batch file (batch.cmd)
@echo off call stock 000001 call stock 000002 call stock 000003 call stock 000004 call stock 000005 call stock 000006 call stock 000007 call stock 股票代码n...
Double-click to open it to display it. If you want to save it to a file, you can execute batch.cmd > log.txt
, and then copy the results to Execl (or ET) for more responsible analysis.
The above is the entire content of using PHP command line mode to collect stock trend information. This function is very convenient and practical. Friends who are interested can quickly practice it.

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,
