of my program

        // Location of the resource (Bug Report)
        $url = "http://localhost:8080/bugzilla/rest/bug/1";

        // Instantiate an instance of cURL
        $curl = curl_init();

        // cURL settings, URL to send request to
        curl_setopt($curl, CURLOPT_URL, $url);

        // cURL settings, Return the response as a string 
        curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);

        // Execute the cURL request
        $result = curl_exec($curl);

        // Close the cURL request
        curl_close($curl);

        //echo "<BR>Product: ". $result->product;
        //echo "<BR>Component: ".$result->component;
        //echo "<BR>Version: ".$result->version;
        //echo "<BR>Summary: ".$result->summary;
        //echo "<BR>Priority: ".$result->priority;
        //echo "<BR>Operating System".$result->op_sys;

I tried using json_encode and json_decode functions and tried to extract properties from object or get information from array but not able to get the product, component, version, summary, priority etc from the $result

Answer 1

Try this

$data = json_decode('your json_code',true);
echo $data['bugs'][0]['component']."<br>";
echo $data['bugs'][0]['product']."<br>";
echo $data['bugs'][0]['version']."<br>";
echo $data['bugs'][0]['summary']."<br>";

Output

TestComponent
TestProduct
unspecified
Checking if Bugzilla REST API is working or not

In json_decode When TRUE, returned objects will be converted into associative arrays.http://php.net/manual/en/function.json-decode.php
