How to call REST API using CURL in php?

php json rest curl

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

I have problem when I am trying to call API using curl. My php code looks like this:

<html>
<head>
<body>
<span style="z-index:50;font-size:0.9em;">
<img src="https://theysaidso.com/branding/theysaidso.png" height="20"  width="20" alt="theysaidso.com"/>
<a href="https://theysaidso.com" title="Powered by quotes from   theysaidso.com" style="color: #9fcc25; margin-left: 4px; vertical-align:  middle;">
theysaidso.com</a></span>
<?php
       $service_url = 'http://quotes.rest/qod.json';
       $curl = curl_init($service_url);
       curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
       curl_setopt($curl, CURLOPT_POST, false);
       curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);
       $curl_response = curl_exec($curl);
       curl_close($curl);
       $json_objekat=json_decode($curl_response);
       echo $json_objekat->contents->quotes->quote.'<br>';
       echo $json_objekat->contents->quotes->author.'<br>';    
?>
</body>
</head>

This code is saved as php file in my root directory on WAMP server. I use WAMP server. And it is written on this website http://quotes.rest/qod.json that you must insert this html too. When I open this php page on WAMP it shows alert:

Notice: Undefined property: stdClass::$contents in C:\wamp\www\IzdavackaKuca\javniServis.php on line 18

Notice: Trying to get property of non-object in C:\wamp\www\IzdavackaKuca\javniServis.php on line 18

Notice: Trying to get property of non-object in C:\wamp\www\IzdavackaKuca\javniServis.php on line 18

Notice: Trying to get property of non-object in C:\wamp\www\IzdavackaKuca\javniServis.php on line 19

JSON on this link http://quotes.rest/qod.json looks like this:

{
    "success": {
        "total": 1
    },
    "contents": {
        "quotes": [
            {
                "quote": "A loser doesn't know what he'll do if he loses, but talks about what he'll do if he wins, and a winner doesn't talk about what he'll do if he wins, but knows what he'll do if he loses.",
                "length": "184",
                "author": null,
                "tags": [
                    "failure",
                    "inspire",
                    "knowledge",
                    "winning"
                ],
                "category": "inspire",
                "date": "2016-05-11",
                "title": "Inspiring Quote of the day",
                "background":       "https://theysaidso.com/img/bgs/man_on_the_mountain.jpg",
                "id": "KhjRMynny89MKxcGkEKF_QeF"
             }
        ]
    }
}

When I change last two lines in php to this:

   echo $json_objekat['contents']['quotes']['quote'].'<br>';
   echo $json_objekat['contents']['quotes']['author'].'<br>';

it alerts:

Fatal error: Cannot use object of type stdClass as array in C:\wamp\www\IzdavackaKuca\javniServis.php on line 18

I realy don`t know how to call this server, when I code:

<?php
   $defaults = array(
        CURLOPT_URL             => 'http://quotes.rest/qod.json',
        CURLOPT_POST            => false,
        CURLOPT_HEADER          => false,
        CURLOPT_SSL_VERIFYPEER  => false,
        CURLOPT_RETURNTRANSFER  => true,
        CURLOPT_SSL_VERIFYHOST  => false,
    );
    $curl               = curl_init();
    curl_setopt_array($curl, $defaults);
    $curl_response      = curl_exec($curl);
    $json_objekat       = json_decode($curl_response);

    // DUMP THE CURL-ERROR INFORMATION:
    var_dump(curl_error($curl));
    curl_close($curl);
?>

it alerts:

string '' (length=0)

Please help!

Just this bracket after $quotes = $json_objekat->contents->quotes is redundant. Thats mistake, I know...
