PHP file_get_contents returning false
提问by Mrk Fldig
Maybe i've been sat here too long staring at this but WHY would file_get_contents return false here, i've cut and paste the URL and it works fine?
也许我已经坐在这里盯着这个看太久了，但为什么 file_get_contents 会在这里返回 false，我已经剪切并粘贴了 URL 并且它工作正常？
$url = "http://jobs.github.com/positions.json?search=" . $as_any . "&location=" . $location;
// URL contains http://jobs.github.com/positions.json?search=Project Manager&location=London
var_dump($url);
$json = file_get_contents($url);
var_dump($json);
$results = json_decode($json, TRUE);
var_dump($results);
exit;
Thanks
谢谢

I Have checked for allow_url_fopen and its definately on.
我已经检查过 allow_url_fopen 并且它肯定是打开的。

Try this:
尝试这个：
$query = http_build_query(array('search'=>$as_any, 'location'=>$location));
$url = "http://jobs.github.com/positions.json?" . $query;
The problem is that you weren't URL-encoding the search term, which contains a space. The request was returning a 400 error from the server, which you'd have noticed if you had error reporting enabled.
问题是您没有对包含空格的搜索词进行 URL 编码。该请求从服务器返回 400 错误，如果您启用了错误报告，您就会注意到这一点。

You may need to enable allow_url_fopen in your php.ini
您可能需要在 php.ini 中启用 allow_url_fopen
http://www.php.net/manual/en/filesystem.configuration.php#ini.allow-url-fopen
http://www.php.net/manual/en/filesystem.configuration.php#ini.allow-url-fopen
From the documentation:
从文档：
This option enables the URL-aware fopen wrappers that enable accessing URL object like files.
此选项启用支持访问 URL 对象（如文件）的 URL 感知 fopen 包装器。
Your server may be preventing you from opening a file located at a URL using file_get_contents.
您的服务器可能阻止您使用 file_get_contents 打开位于 URL 处的文件。

Sometimes if file_get_contentsreturn false(not found) you should see if the url is encoded.
有时，如果file_get_contents返回false（未找到），您应该查看 url 是否已编码。
