How to pass result for CURL request from another domain - php

I have a function that will give some results.
Suppose anyone connecting to my url with CURL and trying to get result, how should I return result for the CURL.
I need to pass JSON in return of that CURL
Is that I need to echo the result or return?
I tested with,
// create a new cURL resource
$ch = curl_init();
// set URL and other appropriate options
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_URL, $myURL); // here passed my url
curl_setopt($ch, CURLOPT_HEADER, 0);
// grab URL and pass it to the browser
$result = curl_exec($ch);
$info = curl_getinfo($ch);
// close cURL resource, and free up system resources
curl_close($ch);
In the url I am doing this,
$model = new Application_Model_Listings();
$result['communtityDetails'] = $model->getCommunityWidgetDetails();
$result = json_encode($result['communtityDetails']);
// return $result; or echo $result ??
CURL connection is happening, but result is not getting.
How should I pass this result??

Get data from an another webpage

I want to to extract buy and sell value from this website
How can I do this using file_get_contents() in PHP
For e.g
$abc = file_get_content("https://www.unocoin.com/trade?all");
Now how can I extract buy and sell value from it in every 2 min?
Here if you want to extract data from other webpage than you use php curl
Example
function curl_download($Url){
// is cURL installed yet?
if (!function_exists('curl_init')){
die('Sorry cURL is not installed!');
}
// OK cool - then let's create a new cURL resource handle
$ch = curl_init();
// Now set some options (most are optional)
// Set URL to download
curl_setopt($ch, CURLOPT_URL, $Url);
// Include header in result? (0 = yes, 1 = no)
curl_setopt($ch, CURLOPT_HEADER, 0);
// Should cURL return or print out the data? (true = return, false = print)
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
// Timeout in seconds
curl_setopt($ch, CURLOPT_TIMEOUT, 10);
// Download the given URL, and return output
$output = curl_exec($ch);
// Close the cURL resource, and free system resources
curl_close($ch);
return $output;
}
print curl_download('https://www.unocoin.com/trade?all');
For this particular site, the data is json encoded so all you need to do is and it does not seem to have any further authentication requirement, as I can just get to the link and see the data.
$abc = file_get_content("https://www.unocoin.com/trade?all");
$decoded_abc=json_decode($abc);
$buy=$decoded_abc->buy;
$sell=$decoded_abc->sell;

How to get variable value from cURL

<?php
$message=$_POST["msg"];
echo $message;
// create a new cURL resource
$ch = curl_init();
// set URL and other appropriate options
curl_setopt($ch, CURLOPT_URL, "http://.../pl1.php?
m=$message");
curl_setopt($ch, CURLOPT_HEADER, 0);
// grab URL and pass it to the browser
curl_exec($ch);
// close cURL resource, and free up system resources
curl_close($ch);
?>
Above is the code iam using.anyone suggest me how do i get value of m in pl1.php
I am getting following error:
Your browser sent a request that this server could not understand.
In PHP variables passed as query string inside URL are accessible in $_GET array.
In your case it will be $_GET['m'].
Try this code:
<?php
$message=$_POST["msg"];
echo $message;
// curl initialize
$ch = curl_init();
// set curl options
curl_setopt($ch, CURLOPT_URL, "http://.../pl1.php?
m=$message");
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
// execute request and return response
$output = curl_exec($ch);
echo $output;
// close cURL request
curl_close($ch);
?>
And to get that data on page pl1.php use $_GET['m'];
But, I believe sending data using curl with post method is better than get method.
Thank you

How to extract data from a decoded JSON object in php

I wanted to try to get data from a JSON string which is loaded from another page. I currently have used Curl to get the data from the webpage but I can't acces the data in it.
I've already tried:
var_dump(json_decode($result->version, true));
var_dump(json_decode($result[3][0]["date"], true));
But this does't seem to work as it always returns NULL
$url="https://roosters.deltion.nl/api/roster?group=AO2B&start=20160125&end=20160201";
// Initiate curl
$ch = curl_init();
// Disable SSL verification
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
// Will return the response, if false it print the response
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
// Set the url
curl_setopt($ch, CURLOPT_URL,$url);
// Execute
$result=curl_exec($ch);
// Closing
curl_close($ch);
// Will dump a beauty json :3
var_dump(json_decode($result, true));
First decode the JSON, then get the properties you want. Like this:
$yourObject = json_decode($result);
var_dump($youObject->version);
this is working for me.
<?php
$url = "https://roosters.deltion.nl/api/roster?group=AO2B&start=20160125&end=20160201";
// Initiate curl
$ch = curl_init();
// Disable SSL verification
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
// Will return the response, if false it print the response
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
// Set the url
curl_setopt($ch, CURLOPT_URL, $url);
// Execute
$result = curl_exec($ch);
// Closing
curl_close($ch);
// Will dump a beauty json :3
$data = json_decode($result);
//echo $data->data[0]['date'];
echo "<pre>";
print_r($data->data[0]->date);
}
?>
if you want to get date of all index then try this in loop.
Firstly if your using GET there is no need to use CURL,
$result = file_get_contents(https://roosters.deltion.nl/api/roster?group=AO2B&start=20160125&end=20160201);
Will work just as well without any of the overhead. I suspect that your CURL isn't returning the page content so using file_get_contents() will fix it.

How to use GET on an external URL

I am using an API that returns JSON from a GET request
Eg.
https://api.domain.com/v1/Account/{auth_id}/Call/{call_uuid}
Returns
{
"call_duration": 4,
"total_amount": "0.00400"
}
How can I call this page from within a script and save call_duation and total_amount as separate variables?
Something like the following?:
$call_duration =
$_GET[https://api.domain.com/v1/Account/{auth_id}/Call/{call_uuid}, 'call_duration'];
$_GET[] contains the get parameters that are passed to your code - they don't generate a GET request.
You could use curl to make your request:
$ch = curl_init("https://api.domain.com/v1/Account/{auth_id}/Call/{call_uuid}");
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$output = curl_exec($ch);
curl_close($ch);
$result = json_decode($output);
If PHP has allow_url_fopen enabled you can simply do
json_decode(file_get_contents('https://api.domain.com/v1/Account/{auth_id}/Call/{call_uuid}'))
Otherwise you'll have to resort to using something like Curl to get the request going. $_GET is a superglobal array which doesn't actually do anything. It only contains what the script was started with. It does not make any requests itself.
Use curl to get the JSON, then json_decode to decode it into PHP variables
$auth_id = 'your auth id here';
$call_uuid = 'your call_uuid here';
// initialise curl, set URL and options
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,"https://api.domain.com/v1/Account/{$auth_id}/Call/{$call_uuid}");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_HEADER, 0);
// get the response and decode it
$response = curl_exec($ch);
curl_close($ch);
$response = json_decode($response);
$call_duration = $response['call_duration'];
$total_amount = $response['total_amount'];

using json data from Curl response

Hi I'm a little new at CURL, but I'm trying to request some json data and then parse the results. I am having success with retrieving the data, but I can't handle the response. Here's the code
function bitBucketCurl($url)
{
global $bitPassword;
global $bitUsername;
$ch = curl_init();
// set URL and other appropriate options
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_USERPWD, "$bitUsername:$bitPassword");
curl_setopt($ch, CURLOPT_HEADER, 0);
// grab URL and pass it to the browser
$commitinfo = curl_exec($ch);
// close cURL resource, and free up system resources
curl_close($ch);
return $commitinfo;
}
$json = bitBucketCurl($url);
echo $json; // This seems to work in that, when I load the page, I can see the json data
//turn json data into an array - this is what does not seem to be working
$obj_a = json_decode($json, true);
print_r ($obj_a); //the result is simply a 1 rather than the array I would expect
The basic problem is the json data shows up when I echo $json but when I try to turn that data into an array it doesn't work. When I print the array, I just get a '1'.
I got the required result by adding the following line:
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
