I have written similar things before in the company. This time I wrote a simple collection program for my former boss.

Very simple. . sweat. Nothing technical.
Data source: http://cn.finance.yahoo.co...
Demo address: http://traffic02.100steps....

(Modified, added Data caching function. . . I didn’t use lite_cache anymore, so I wrote the simplest one. )

Copy the code as follows:

set_time_limit(0);

$max_time=3600;
$cache_file='cache_yahoo.txt';

$nowtime=time();
if(!file_exists($cache_file)){
$filetime=0;
}else{
$filetime=filemtime($cache_file);
}

if($filetime+$max_time<$nowtime){
//更新
ob_start();
function get_yahoo_info($url){
$content=file_get_contents($url);

$pattern='|(.*) \((.*)\)  (.*)|U'; 
    preg_match_all($pattern,$content,$out); 
    $info['company_name']=$out[1][0]; 
    $info['company_stock']=$out[2][0]; 

    $pattern='|最近交易价:(.*)|U'; 
    preg_match_all($pattern,$content,$out); 
    $info['stock_price']=$out[1][0]; 

    $pattern='|涨跌:(.*)|U'; 
    preg_match_all($pattern,$content,$out); 
    $info['stock_upordown']=$out[1][0]; 

    $pattern='|市值:(.*)|U'; 
    preg_match_all($pattern,$content,$out); 
    $info['stock_value']=$out[1][0];     

    return $info; 

$urls=explode(',',file_get_contents('url.txt')); 
$i=0; 
$matchs=array(); 
foreach($urls as $url){ 
    $rs=get_yahoo_info($url); 
    if(!empty($rs)){ 
        $matchs[$i]=$rs; 
        $i++; 
        $rs=''; 
    } 


//print_r(get_yahoo_info('http://cn.finance.yahoo.com/q?s=000063.SZ')); 
?> 
 
   
     
     
     
     
     
     
   
    $i=1; 
foreach($matchs as $match){ 
  ?> 
   
     
     
     
     
     
     
  
 
    $i++; 
  }?> 
 
公司名称
股票代号
股票价格
股票涨幅
市值
 
    $content=ob_get_clean(); 
    $fp=fopen($cache_file,'w'); 
    if(!$fp)echo '打开文件失败'; 
    if (flock($fp, LOCK_EX)) { // 进行排它型锁定 
        if(!fwrite($fp, $content))echo '文件写入失败'; 
        flock($fp, LOCK_UN); // 释放锁定 
    } else { 
        //echo "Couldn't lock the file !"; 
        if(!fwrite($fp, $content))echo '文件写入失败'; 
    } 
    fclose($fp); 
    //echo 'cache time:'.time(); 
    echo $content; 
}else{ 
    //echo 'cache!'; 
    echo file_get_contents($cache_file); 

?>
