Question

我有一个循环，其中我将一些图像保存在本地，然后将其移至S3

foreach ($images as $image) {
    // download image
    $stream = fopen($image['path'], 'wb');
    write($stream, $image['content']);
    fclose($stream);

    // copy to S3
    $manager->copy('local://' . $image['p'], 's3://' . $image['p']);
}

问题是我遇到failed to open stream: Too many open files error错误

任何想法如何避免这种情况？

Warning: include(/var/www/vendor/monolog/monolog/src/Monolog/Formatter/LineFormatter.php): failed to open stream: Too many open files in /var/www/vendor/composer/ClassLoader.php on line 444 Fatal error: Uncaught Error: Class 'Monolog\Formatter\LineFormatter' not found in /var/www/vendor/symfony/monolog-bridge/Handler/ConsoleHandler.php:155

在飞行系统的aws-s3驱动程序中增加ulimit -n或禁用分段上传。是flysystem保持太多文件打开。

好的，快速解决方案是：

foreach ($images as $image) {

   $resourcesOpened = count(get_resources('stream'));

     while ( $resourcesOpened > 900 ) {
       sleep(10);
       $resourcesOpened = count(get_resources('stream'));
     }

     // download image
     $stream = fopen($image['path'], 'wb');
     write($stream, $image['content']);
     fclose($stream);

     // copy to S3
     $manager->copy('local://' . $image['p'], 's3://' . $image['p']);
   }


}
