存储 API 以前的值并与新值进行比较

Question

我开发了一个电报机器人，它的工作是在电报组中发布板球比赛的比分。只有在更新新分数时才需要发布分数。我正在尝试将旧分数存储在会话中，然后将其与新分数进行比较。

如果两个值（旧值和新值）不匹配，请将分数发布到组中，但由于某种未知原因，它不起作用

这是我的代码

<?php

session_start();

set_time_limit(0);


$token = 'xyz';
$group_name = 'xyz';


while(true){

$ipl = file_get_contents('https://cricket-api.vercel.app/cri.php?url=https://www.cricbuzz.com/live-cricket-scores/37632/dc-vs-csk-50th-match-indian-premier-league-2021');  

$ipl_data = json_decode($ipl, true);

$current_score = $ipl_data['livescore']['current'];
        
if($current_score != $_SESSION['old_score']){
  $bot = "https://api.telegram.org/bot{$token}/sendMessage?chat_id={$group_name}&text={$current_score}";
  $hit = file_get_contents($bot);      
} 

$_SESSION['old_score'] = $current_score;
    


sleep(10);    

}
 

?>

Answer 1

看那个

$_SESSION['old_score'] = $current_score;

if($current_score != $_SESSION['old_score'])

您的会话 "old_score" 始终等于 $current_score 首先尝试您的if，然后更改会话字段

if($current_score != $_SESSION['old_score']){
       
} 

$_SESSION['old_score'] = $current_score;
