What I want to achieve is unserialize all the data I am getting from the below link and get it converted to php array
http://ip-api.com/php
I know I can use unserialize() function of php and pass the serialized string to get it converted.
how can I convert the response of above link to php array ?
thanks
I generally use curl to get the content from external link
Do the following
$c = curl_init();
curl_setopt($c, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($c, CURLOPT_URL, 'http://ip-api.com/php');
$contents = curl_exec($c);
curl_close($c);
print_r(unserialize($contents));
your result array will look like below
Array ( [query] => 43.231.208.107 [region] => [timezone] => Asia/Kathmandu [org] => ClassicTech Pvt. [as] => AS55915 Classic Tech Pvt. Ltd. [city] => Kathmandu (Koteshwor) [zip] => [isp] => ClassicTech Pvt. [status] => success [lat] => 27.684499740601 [lon] => 85.34839630127 [country] => Nepal [countryCode] => NP [regionName] => Central Region )
also you can create a function and pass the url if you like to clean up the code.
You can also use file_get_contents() to archive this.
$result = file_get_contents('http://ip-api.com/php');
var_dump(unserialize($result));

I tried to do my first API calls which worked finally with help from this great users here in this community. Thanks again. I want to choose data[1] or the currency with symbol. So i could use a $variable from my CMS. Maybe someone can show me a way how i can change this call to symbol. Here is my API call.
$url = "https://pro-api.coinmarketcap.com/v1/cryptocurrency/listings/latest";
$headers = [
'Accepts: application/json',
'X-CMC_PRO_API_KEY: ___YOUR_API_KEY_HERE___'
];
$request = "{$url}"; // create the request URL
$curl = curl_init(); // Get cURL resource
// Set cURL options
curl_setopt_array($curl, array(
CURLOPT_URL => $request, // set the request URL
CURLOPT_HTTPHEADER => $headers, // set the headers
CURLOPT_RETURNTRANSFER => 1 // ask for raw response instead of bool
));
$response = curl_exec($curl); // Send the request, save the response
$json = json_decode($response);
curl_close($curl); // Close request
$price = $json->data[1]->quote->USD->price; echo $price;
You get the data block IDs with array_column(), then you get the symbol's data block ID with array_search():
$data_ids = array_column($json->data, 'symbol');
$symbol_data_id = array_search('ETH', $data_ids);
$price = $json->data[$symbol_data_id]->quote->USD->price;
Or as an oneliner:
$price = $json->data[array_search('ETH', array_column($json->data, 'symbol'))]->quote->USD->price;
LATER UPDATE: OK, let me elaborate on this. Step by step:
You need a proper URL to acces the API. For this you need the API documentation. Your original question mentioned
$url = "https://pro-api.coinmarketcap.com/v1/cryptocurrency/listings/latest";
while for your comment question you need something like
$url = "https://pro-api.coinmarketcap.com/v1/cryptocurrency/info?symbol=ETH";
A proper URL will give you a JSON response structured according to its purpose. You have this part ironed out, so I'll not insist on this. From your question text:
$headers = [
'Accepts: application/json',
'X-CMC_PRO_API_KEY: 1b58ff56-58b2-4fd0-b184-f9c3dd4ff106',
];
$request = "{$url}"; // create the request URL
$curl = curl_init(); // Get cURL resource
// Set cURL options
curl_setopt_array($curl, [
CURLOPT_URL => $request, // set the request URL
CURLOPT_HTTPHEADER => $headers, // set the headers
CURLOPT_RETURNTRANSFER => 1, // ask for raw response instead of bool
]);
$response = curl_exec($curl); // Send the request, save the response
$json = json_decode($response);
curl_close($curl); // Close request
Then you have to decide how to use the response. For me, the fastest way is to look at its structure (var_dump($json) or print_r($json)). Which will give something like this (the original question):

So data is a property of the $json object.
In the first case, data is an array and its structure suggests using array functions to retrieve specific data.
In the second case, data and ETH are objects, while description is a property of ETH. Which allows me to get the description using object syntax
$description = $json->data->ETH->description;
I've been working on this SoundCloud website for awhile now and have just got into creating a stream page alternative that will display on our website. I have stumbled into an issue however and I'm sure it's an easy solution I'm just now figuring out how 2 achieve the proper output.
$user_ID = $_GET['id'];
$sc = curl_init();
curl_setopt($sc, CURLOPT_URL, 'http://api.soundcloud.com/users/'.$user_ID.'/followings?client_id='.$client_ID.'&page_size=200&cursor=1419617528000');
curl_setopt($sc, CURLOPT_HEADER, 0);
curl_setopt($sc, CURLOPT_RETURNTRANSFER, true);
$output = curl_exec($sc);
curl_close($sc);
$content = json_decode($output, true);
As you can see above the code currently is suppose to display up to 400 users in which someone is following, however when we do the following 2 return all of the content which is being displayed on that link.
echo "<pre>";
print_r($content);
echo "</pre>";
It appears that it caps at only 200 results ( which is really not that good we need 2 find an alternative 2 display the full amount of users someone is following. ) at the bottom of th page it displays another message.

However, even using this method does nothing (even though I'm more then certain the user I am testing with has more then 200 users he's following.)
EDIT : Someone here is having the same issue, how ever I don't understand the comment solution on how 2 prevent it from happening..
I am using the code below to get some data from the json response using the url provided. This is mainly to get lat long from given coordinates for a site I am creating. I am not sure why I am getting
"Trying to get property of non-object"
error but I may have made a mistake as I have not used JSON before
$ch = curl_init();
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_URL, 'https://api.postcodes.io/postcodes/cm20re?callback=foo');
$result = curl_exec($ch);
curl_close($ch);
$obj = json_decode($result);
echo $result
Now I get this echoed on the screen
/**/ typeof foo === 'function' && foo({"status":200,"result":{"postcode":"CM2 0RE","quality":1,"eastings":570635,"northings":206427,"country":"England","nhs_ha":"East of England","longitude":0.469458924538463,"latitude":51.7305869996012,"parliamentary_constituency":"Chelmsford","european_electoral_region":"Eastern","primary_care_trust":"Mid Essex","region":"East of England","lsoa":"Chelmsford 010D","msoa":"Chelmsford 010","incode":"0RE","outcode":"CM2","admin_district":"Chelmsford","parish":"Chelmsford, unparished area","admin_county":"Essex","admin_ward":"Moulsham and Central","ccg":"NHS Mid Essex","nuts":"Heart of Essex","codes":{"admin_district":"E07000070","admin_county":"E10000012","admin_ward":"E05004107","parish":"E43000062","ccg":"E38000106","nuts":"UKH36"}}});
Not sure how to pick a specific value
here is the print value

You need to fetch data from your json_decode function instead your curl result
So change
$obj = json_decode($result);
echo $result->eastings;// You need to fetch it form $obj instead of $result
To
$obj = json_decode($result);
echo $obj->eastings;// use $obj
Updated
You can get your value using
$obj->result->eastings
I am able to retrieve results from yahoo with my API key, using the instructions found on the yahoo developers website. http://developer.yahoo.com/boss/search/boss_api_guide/codeexamples.html#
Code:
if ($_POST['query'])
{
$newline="<br />";
$query = urlencode("'{$_POST['query']}'");
require("OAuth.php");
$cc_key = "key goes here";
$cc_secret = "secret goes here";
$url = "http://yboss.yahooapis.com/ysearch/web";
$args = array();
$args["q"] = "$query";
$args["format"] = "json";
$consumer = new OAuthConsumer($cc_key, $cc_secret);
$request = OAuthRequest::from_consumer_and_token($consumer, NULL,"GET", $url, $args);
$request->sign_request(new OAuthSignatureMethod_HMAC_SHA1(), $consumer, NULL);
$url = sprintf("%s?%s", $url, OAuthUtil::build_http_query($args));
$ch = curl_init();
$headers = array($request->to_header());
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
$rsp = curl_exec($ch);
$results = json_decode($rsp);
print_r($results);
}
Using print_r($results) as shown above, I get results, such as the following (extract of first three results shown from searching for "elephant"):

I have attempted to output the results, in a legible format, as follows:
Code Attempt 1:
foreach ($results->{ 'results' } as $item )
{
echo "<font color ='blue'>{$item->{ 'title' }}</font>".": "."$newline"."$newline".$item->{ 'abstract' }."\n\n";

Any ideas on what to do?
Thanks.
I've noticed you just copy-pasted the code from the documentation's code examples, but never mind that.
You're accessing the results array the wrong way:
foreach ($results->bossresponse->web->results as $result)
{
//do stuff
echo $result->title.'<br/>';
}
Or, as cptnk suggested:
$results = json_decode($rsp, true);
//force to assoc-array, which will allow array-access
foreach($results['bossresponse']['web']['results'] as $result)
{
//$result is array here, but do the same stuff
echo $result['title'].'<br/>';
}
Or, combine the two
foreach($results->bossresponse->web->results as $result)
{
$result = (array) $result;//casts stdClass to array
printf('%s<br/>', $result['url'], $result['title']);
}

My question is how do I paginate results, since all the 50 results appear on the first web page only. I want to display ten results in every page.
Any help is appreciated.
Thanks.
According to the Yahoo! BOSS documentation, specifically the Universal Arguments section, it looks like you can use the start and count parameters to adjust the pagination of results. It looks like the default return count is 50 which matches what you observed.
In your code example you can adjust by adding:
$args["start"] = 0; // increment as needed
$args["count"] = 10;
