Call a Rest API in PHP

Call a REST API in PHP

You can access any REST API with PHPs cURL Extension. However, the API Documentation (Methods, Parameters etc.) must be provided by your Client!

Example:

// Method: POST, PUT, GET etc
// Data: array("param" => "value") ==> index.php?param=value

function CallAPI($method, $url, $data = false)
{
    $curl = curl_init();

    switch ($method)
    {
        case "POST":
            curl_setopt($curl, CURLOPT_POST, 1);

            if ($data)
                curl_setopt($curl, CURLOPT_POSTFIELDS, $data);
            break;
        case "PUT":
            curl_setopt($curl, CURLOPT_PUT, 1);
            break;
        default:
            if ($data)
                $url = sprintf("%s?%s", $url, http_build_query($data));
    }

    // Optional Authentication:
    curl_setopt($curl, CURLOPT_HTTPAUTH, CURLAUTH_BASIC);
    curl_setopt($curl, CURLOPT_USERPWD, "username:password");

    curl_setopt($curl, CURLOPT_URL, $url);
    curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);

    $result = curl_exec($curl);

    curl_close($curl);

    return $result;
}

Calling the rest api in php

Here is the php code to send request using curl.

$s = curl_init(); 
curl_setopt($s,CURLOPT_URL,'https://affiliate-api.flipkart.net/affiliate/1.0/feeds/abhishekbh/category/7jv.json?expiresAt=1489539219049&sig=ad5ef1af7f41d68d9f8f1c1ae85e20b6'); 
curl_setopt($s,CURLOPT_HTTPHEADER,array('Fk-Affiliate-Id:abhishekbh', 'Fk-Affiliate-Token:2dacb05681b8481eb65291283dac2630')); 
curl_setopt($s,CURLOPT_HEADER,true);
$result = curl_exec($s);

echo "<pre>";print_r($result);echo "</pre>";

PHP REST client API call

You can use file_get_contents if the fopen wrappers are enabled. See: http://php.net/manual/en/function.file-get-contents.php

If they are not, and you cannot fix that because your host doesn't allow it, cURL is a good method to use.

How to call REST API using CURL in php?

The issue is because you are accesing quote and author incorrectly.
Output of print_r($json_objekat) says that:

contents is stdClass Object

quotes is array

again quotes is having
0 as index which is again stdClass Object

So, try accessing quote and author as follows:

$json_objekat->contents->quotes[0]->quote

$json_objekat->contents->quotes[0]->author

Call rest API to upload file with form data using cUrl PHP

$file = $request->file('image');
$filePath = $file->getPathName();
$type = 'image/jpeg';
$fileName = $file->getClientOriginalName();

$data = array(
    'shopId' => 50,
    'image' => curl_file_create($filePath, $type, $fileName)
);

$apiEndPoint='http://localhost/test/api/api/retailer/shop/update/image';

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $apiEndPoint);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: multipart/form-data'));
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
$response = curl_exec($ch);
curl_close($ch);
