Question

I use below code to fetch an url, this works successfully, It returns an json data

$url =  "https://graph.facebook.com/me?access_token=".$access_token;


    function fetch_url($url){

        import java.net.URL;
        import java.io.BufferedReader;
        import java.io.InputStreamReader;

        $java_url = new URL($url);
        $java_bufferreader = new BufferedReader(new InputStreamReader($java_url->openStream()));

        while (($line = $java_bufferreader->readLine()) != null) {
            $content .= $line;
        }

        return $content;
    }

    // Sample usage:
    $friends = fetch_url($url);

when i echo $friends I get the below json code,

{

   "id": "100003185423323",
   "name": "hnu Chid",

I cant use json decode on GAE,When i try to json decode i get server error, is there any other way to parse it on php , please help me.

Answer 1

1. Make sure that json_decode exists (is enabled).

<?php
if (function_exists('json_decode')) {
    echo "json_decode functions is available.<br />\n";
} else {
    echo "json_decode functions is not available.<br />\n";
}
?>

2. Use try catch to catch parsing errors.

<?php
try {
     $response = json_decode($friends, true);
     print_r($response);
} catch (Exception $ex) {
     echo 'Caught exception: ',  $ex->getMessage(), "<br/>\n";
     var_dump($friends);
}
?>
