如何使用file_get_contents()加载远程文件? [英] How can I load a remote file using file_get_contents()?

问题描述

现在用这个挠头.
我正在尝试从远程URL获取文件.我可以从本地文件中保存内容，但不能从远程文件中保存.

Scratching my head a bit now with this.
I am trying to get a file from a remote url. I can save contents from local files, but can't from remote.

这有效:

file_put_contents(
    'file1.xml',
    file_get_contents('file2.xml')
);

这不是:

file_put_contents(
    'file1.xml',
    file_get_contents('http://www.domain.com/xmlapi/search.aspx?query=places&lid=38')
);

奇怪的是，我的其他脚本在第一次尝试时就可以正常运行，但是现在没有一个可以访问远程URL.
我最近开始在Heart Internet上托管我的新php文件.我在其他服务器上也有类似的脚本，这些脚本完全没有问题.

Oddly enough my other scripts worked ok at first try but none will access the remote url now.
I have recently started to host my new php files on Heart Internet. I have similar scripts on other servers which give no problems at all.

这是我得到的错误:

警告:file_get_contents()[function.file-get-contents]:php_network_getaddresses:getaddrinfo失败:名称或服务在第5行的/home/sites/mydomain/myfile.php中不知道

Warning: file_get_contents() [function.file-get-contents]: php_network_getaddresses: getaddrinfo failed: Name or service not known in /home/sites/mydomain/myfile.php on line 5`

警告:file_get_contents( http://www.domain .com/xmlapi/search.aspx?query = places& lid = 38 )[function.file-get-contents]:无法打开流:php_network_getaddresses:getaddrinfo失败:/home/中未知的名称或服务第5行上的sites/mydomain/public_html/myfile.php`

allow_url_fopen设置为On

不同的域

推荐答案

检查php设置...

check the php settings...

这可能是由于安全问题导致的."allow_url_fopen = On"

it may be due to security issue... "allow_url_fopen = On"
