尝试从API输出解析XML / JSON

Question

OK... I am using PHP 5 (be gentle, still learning PHP). CURL is enabled. Attempting to load XML or JSON output from an API to an object and nothing happens. When I manually execute the URL in question, I get what I am expecting.

Here is my code:

class XmlToJson {
    public function Parse ($url) {
        $fileContents = file_get_contents($url);
        $fileContents = str_replace(array("\n", "\r", "\t"), '', $fileContents);
        $fileContents = trim(str_replace('"', "'", $fileContents));
        $simpleXml = simplexml_load_string($fileContents);
        $json = json_encode($simpleXml);
        return $json;
    }
}

$_MySQLServer = "localhost";
$_MySQLServerUserName = "";
$_MySQLServerPassword = "";
$_MySQLDatabaseName = "";

$_SSActiveWear_UserID = "*****";
$_SSActiveWear_APIKey = "*****";
$_SSActiveWear_APIBaseURL = "https://*****/v2";
$_CategoryURL = "/categories/";
$_StylesURL = "/styles/";
$_ProductsURL = "/products/";
$_SpecsURL = "/specs/";
$_SSActiveWear_MediaType = "xml";

//$_conn = mysqli_connect($_MySQLServer, $_MySQLServerUserName, $_MySQLServerPassword, $_MySQLDatabaseName);

//Insert or Update Categories
$_URL = $_SSActiveWear_APIBaseURL . $_CategoryURL;
$_URL = $_URL . "?mediatype=$_SSActiveWear_MediaType&UserName=$_SSActiveWear_UserID&Password=$_SSActiveWear_APIKey";

$OBJ = simplexml_load_string($_URL);

print_r($OBJ);

What am I doing wrong?

Edit 1

Added the following code:

$xml = simplexml_load_file($_URL) or die("Error: Cannot create object");
print_r($xml);

and it dies. Does that mean that there is something wrong with the code?

Answer 1

Try this :

$OBJ = simplexml_load_string(file_get_contents($_URL));

If you want to know why your code is not working, you are trying to load XML from URL but "simplexml_load_string" loads XML from string.

I FINALLY figured it out... More to the point I finally found a site on Google that helped. It is the first answer in fsockopen with http authentication problem .

So here is the code that works:

file_get_contents("https://$_SSActiveWear_UserID:$_SSActiveWear_APIKey@$_SSActiveWear_APIBaseURL$_CategoryURL/?mediatype=$_SSActiveWear_MediaType");

mediatype can be either json or xml
