使用下面的每个图像下载代码)file_get_contents())平均需要8-15秒.....

如果我不在file_get_contents()上使用上下文,那么图像下载不到一秒钟.

如果我将$ opts更改为,那么我获得与file_get_contents()相同的性能,而没有上下文需要花费13秒来处理2,500个图像x.

$opts = array(
    'http'=>array(
        'protocol_version'=>'1.1',
        'method'=>'GET',
        'header'=>array(
            'Connection: close'
        ),
        'user_agent'=>'Image Resizer'
     )
);
