Unable to open remote XML file using fopen(). What all permission i need to set in server or what parameters i need to set in fopen() function.?

问题

I am trying to open an XML file in remote server through fopen() function. I have two remote servers and the file permission of the xml is set to 777 in both servers. i am able to open the xml from one server , but not from other. Both files can be opened in browser.

What all permission i need to set or what parameters i need to set in fopen() function.?

this is the function

function getFileData($ProjectName)
{
    $file = fopen($ProjectName, "r") or exit("Unable to open File! ".$ProjectName);
    $fileContent="";
        while(!feof($file))
          {
         $fileContent.=fgets($file);
          }
    fclose($file);
    echo $fileContent;
}

getFileData('http://serverA.com/myxml.xml'); // gives the content
getFileData('http://serverB.com/myxml.xml'); // gives the error fopen(http:/serverB.com/myxml.xml) [function.fopen]: failed to open stream: HTTP request failed!

回答1:

You only have one / after http: in the last two lines - but I doubt that's the problem. Can you open the file in the browser?

Perhaps try using file_get_contents . It does the same as your function, except it's ready made and fully tested by the PHP guys.

回答2:

I think there should be http://server and not http:/server.

回答3:

Apart from the visible problem with URL, also check what is the value for allow_url_fopen set in your php.ini, if you can open file from one server but not from other server this may be correctly set for you, did you check about timeouts?
