CronJob未在Drupal7中自动运行

家庭管理配置系统

在管理面板cronsetting页面中,检查 强制运行

function hello_cronapi($op, $job = NULL){
   $items['example_sendmail_cron'] = array(
    'description' => 'Send mail with news',
    'rule' => '* * * * *', // Every 5 minutes
  );

  $items['example_news_cron'] = array(
    'description' => 'Send mail with news',
    'rule' => '*/15 * * * *', // Every 5 minutes
    // i must call: example_news_fetch('all')
    'callback' => 'example_news_cron',
    'arguments' => array('all'),
  );
    return $items;

}

函数示例_sendmail\u cron(){

    echo "Company"; 
    $myfile = fopen("newfile.txt", "w") or die("Unable to open file!");
    $txt = "John Doe\n";
    fwrite($myfile, $txt, FILE_APPEND | LOCK_EX);
    $txt = "Jane Doe\n";
    fwrite($myfile, $txt, FILE_APPEND | LOCK_EX);
    fclose($myfile);

    exit;
}
function example_news_cron() {

    echo "Company"; 
    $myfile = fopen("newfile2.txt", "w") or die("Unable to open file!");
    $txt = "John Doe\n";
    fwrite($myfile, $txt, FILE_APPEND | LOCK_EX);
    $txt = "Jane Doe\n";
    fwrite($myfile, $txt, FILE_APPEND | LOCK_EX);
    fclose($myfile);

    exit;
}

在上面的cronjob中,创建一个文件并将内容放入该文件中。但文件不是创建的
