cron作业报错

我用下面的代码cron作业：cron作业报错

<?php 
require "config.php"; 
$truncate = $mysqli->query("TRUNCATE rss_feed"); 

$cars = $mysqli->query("SELECT *,(SELECT title FROM companies WHERE companies.company_id = cars.company_id) AS car_company,(SELECT car_model FROM models WHERE models.model_id = cars.model_id) AS car_model FROM cars, companies WHERE cars.company_id = companies.company_id AND car_active = 'Active' AND rssPost IS NULL ORDER BY datetime DESC"); 
$result = $cars->num_rows; 

if ($result > 0) { 
    while ($row_cars = $cars->fetch_array()) { 
     $title = $row_cars['car_company'] . ' ' . $row_cars['car_model'] . ' ' . $row_cars['car_cc']; 
     $link = '/car.php?id=' . $row_cars['car_id']; 
     $description = $row_cars['car_description']; 
     $datetime = $row_cars['datetime']; 
     $row_car_id = $row_cars['car_id']; 

     $insert = $mysqli->query("INSERT INTO rss_feed (title, link, description, datetime) VALUES ('$title','$link','$description','$datetime')"); 
     $update = $mysqli->query("UPDATE cars SET rssPost='Yes' WHERE car_id = '$row_car_id'"); 

     if (!$insert) { 
      printf("ERROR: %s\n", $mysqli->error); 
     } 
    } 
    printf($result . " cars inserted"); 
} else { 
    printf("No new cars inserted"); 
}

我设置的cPanel运行PHP文件每3个小时，我得到了他以下错误：

/public_html/system/cron_rss.php: line 1: ?php: No such file or directory 
/public_html/system/cron_rss.php: line 2: require: command not found 
/public_html/system/cron_rss.php: line 3: syntax error near unexpected token `(' 
/public_html/system/cron_rss.php: line 3: `$truncate = $mysqli->query("TRUNCATE rss_feed");'

如果我通过URL运行该文件，它可以正常工作，没有错误。我的IDE编辑器确认没有可疑代码。我得到了文件的755 CHMOD。

从看来，你是不是用正确的cron调用脚本的第一个错误行。

根据您的主机和您的可能性，您可以尝试下列操作之一：

指定cron项是这样的：

* * * * * /usr/bin/php <path_to_your_script>

或指定cron项是这样的：

php -q <path_to_your_script>

或者您可以尝试在脚本的第一行中写入：

#!/usr/bin/php

你也可以检查这个讨论可以帮助：

好像'PHP -q'在首位丢失。你的答案清除了这一点。我会在2h检查一下，cron会再次运行。 –

只是为了确认，'php -q'是个问题。一切运作良好。谢谢你们 –

尝试具有cron作业使用wget或curl打URL
