PHP file_get_contents返回false [英] PHP file_get_contents returning false

问题描述

也许我在这里呆了太久，但是为什么file_get_contents在这里返回false，我剪切并粘贴了URL并可以正常工作?

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?

     $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;

谢谢

我已经检查了allow_url_fopen及其确定的地址.

I Have checked for allow_url_fopen and its definately on.

推荐答案

尝试一下:

$query = http_build_query(array('search'=>$as_any, 'location'=>$location));
$url = "http://jobs.github.com/positions.json?" . $query;

问题是您没有对包含空格的搜索词进行URL编码.该请求正在从服务器返回400错误，如果您启用了错误报告，则会注意到该错误.

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.
