PHP Curl Work in somecase and not in somecases - php

This Code is Working Well
<?php
// create curl resource
$ch = curl_init();
// set url
curl_setopt($ch, CURLOPT_URL, "http://ipdev.in/");
//return the transfer as a string
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
// $output contains the output string
$output = curl_exec($ch);
echo $output;
// close curl resource to free up system resources
curl_close($ch);
?>
But below two bunch of codes are not working. I am not getting an error but in these cases browser loading bar is just revolving and revolving and never stops. The page shows loading and loading for a long time but nothing loads from URL. Where is the problem ?
<?php
// create curl resource
$ch = curl_init();
// set url
curl_setopt($ch, CURLOPT_URL, "https://iiitd.ac.in/");
//return the transfer as a string
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
// $output contains the output string
$output = curl_exec($ch);
echo $output;
// close curl resource to free up system resources
curl_close($ch);
?>
<?php
// create curl resource
$ch = curl_init();
// set url
curl_setopt($ch, CURLOPT_URL, "http://iiitd.ac.in");
//return the transfer as a string
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
// $output contains the output string
$output = curl_exec($ch);
echo $output;
// close curl resource to free up system resources
curl_close($ch);
?>


the link https://iiitd.ac.in/ is redirecting to https://www.iiitd.ac.in/ so you need to modify your curl code. You need to set CURLOPT_FOLLOWLOCATION as true.
Have a look on below solution:
<?php
// create curl resource
$ch = curl_init();
// set url
curl_setopt($ch, CURLOPT_URL, "https://iiitd.ac.in/");
//return the transfer as a string
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
// added follow location
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
// $output contains the output string
$output = curl_exec($ch);
echo $output;
// close curl resource to free up system resources
curl_close($ch);

Show contents of webpage with CURL. Fifa website

I am trying to get the contents of this webpage to be shown.
https://sofifa.com/players?aeh=22&ptl=84&pth=99&pn=27&pn=25&pn=23?
But unfortunately, it is not working.
Here is the code
<?php
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
$ch = curl_init("https://sofifa.com/players?aeh=22&ptl=84&pth=99&pn=27&pn=25&pn=23");
// Now set some options (most are optional)
// Set URL to download
curl_setopt($ch, CURLOPT_URL, $ch);
// User agent
curl_setopt($ch, CURLOPT_USERAGENT, "MozillaXYZ/1.0");
// 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 $output;
}
?>
<?php
include_once('AFIFAtest.php');#this is the file name of the program
curl_download($url);
?>

Post data from Android App to Backend PHP

If i assign a value to a variable and pass it to url, it is working fine.
$waybill=508518;
$url = 'http://api.ecomexpress.in/track_me/api/mawbd/?awb='.$waybill.'&order=&username=cs#subhashreeinfotech.com&password=####';
$ch = curl_init(); // initiate curl
curl_setopt($ch, CURLOPT_URL,$url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); // return the output in string format
$output = curl_exec ($ch);
But what i need is , i have to get the waybill number dynamically from android app.For that i am posting the waybill value to back end php code like below.But its not working
$waybill=$_POST['bill'];
$url = 'http://api.ecomexpress.in/track_me/api/mawbd/?awb='.$waybill.'& order=&username=cs#subhashreeinfotech.com&password=####';
$ch = curl_init(); // initiate curl
curl_setopt($ch, CURLOPT_URL,$url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); // return the output in string format
$output = curl_exec ($ch);
Error : undefined index bill

Solved the issue using the following code
$waybill=$_POST['srt'];
ob_start();
echo $_POST['srt'];
$my = ob_get_contents();
$url='http://52.66.178.241//track_me/api/mawbd/?
awb='.$my.'&order=&username=subhashree54396&password=su54nbh39tmed';
$ch = curl_init(); // initiate curl
curl_setopt($ch, CURLOPT_URL,$url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); // return the output in
string format
$output = curl_exec ($ch);
print_r($output);
curl_close($ch);

php cURL return size increase

I'm Currently proxying an endpoint by running a cURL however the size of my cURL is about 10 times larger than the original API, Why is that, and how can I decrease the size? This is all JSON BTW.
Original API return size = 32.2kb
cURL return size = 488KB
And here is my cURL script:
$ch = curl_init();
// set url
$url = 'http://domain.com/api/v1';
// set options
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_IPRESOLVE, CURL_IPRESOLVE_V4 );
curl_setopt($ch, CURLOPT_ENCODING, '');
curl_setopt($ch, CURLOPT_TIMEOUT, 5);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
// $output contains the output string
$output = curl_exec($ch);
// close curl resource to free up system resources
curl_close($ch);
return $output;

ob_start('ob_gzhandler');
php output buffer controll was the fix to my problem. Thanks all that tried to help!

using cURL to retrieve JSON data for use with jQuery

I've been reading this helpful post:
http://techslides.com/hacking-the-google-trends-api
It shows how you can use cURL in command line/terminal to request data from google trends, for example;
curl --data "ajax=1&cid=actors&geo=US&date=201310" http://www.google.com/trends/topcharts/trendingchart
Gives you a big block of what I think is JSON. Below is an example of what I am doing to use cURL within my PHP to get data like this- however I cannot find anything that would get the data from the above cURL command to work in PHP like below.
<?php
//initialize session
$url = "http://www.google.com/trends/hottrends/atom/feed?pn=p1";
$ch = curl_init();
//set options
curl_setopt($ch, CURLOPT_URL, $url);
//execute session
$data = curl_exec($ch);
echo $data;
//close session
curl_close($ch);
?>
How do I go about getting the data from above?

You can do the same with the PHP cURL extension. You just need to set the options through curl_setopt, so you would do something like this
$url = "http://www.google.com/trends/topcharts/trendingchart";
$fields = "ajax=1&cid=actors&geo=US&date=201310";
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $fields);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$data = curl_exec($ch);
curl_close($ch);
Now you have the response of the website in $data and you can do whatever you want with it.
You can find the PHP cURL documentation on http://php.net/curl

Try this
// Complete url with paramters
$url = "http://www.google.com/trends/topcharts/trendingchart?ajax=1&cid=actors&geo=US&date=201310";
// Init session
$ch = curl_init();
// Set options
curl_setopt($ch, CURLOPT_URL, $url);
// Set option to return the result instead of echoing it
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
// Execute session
$data = curl_exec($ch);
// Close session
curl_close($ch);
// Dump json decoded result
var_dump(json_decode($data, true));

PHP - echo json off url

I am trying to echo json of of a url. I can't figure out how to do it. I have tried many things. Can someone tell me why my code is not functioning properly? No json gets echoed to the screen. Thanks! Here is the link http://www.eastbay.com/shoppingcart/gateway?action=requestKey&_=
<?php
$raw_json = file_get_contents('http://www.eastbay.com/shoppingcart/gateway?action=requestKey&_=');
$json_array = json_decode($raw_json, true);
echo $json_array;
?>

Its not very pretty, you could put this in a loop but it wil get you started, I hope. Only thing you need to do is change the path where you want to store the cookies, it must be an absolute path.
<?php
$cookies = 'C:/folder/folder..../cookies.txt'; //use a absolute path
//Part 1 to get the cookies
// create curl resource
$ch = curl_init();
// set url
curl_setopt($ch, CURLOPT_URL, "http://www.eastbay.com");
//return the transfer as a string
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true );
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($ch, CURLOPT_COOKIEFILE, $cookies); // Send Cookies.
curl_setopt($ch, CURLOPT_COOKIEJAR, $cookies); // Receive Cookies.
// $output contains the output string
$output = curl_exec($ch);
// close curl resource to free up system resources
curl_close($ch);
//part 2 to get the json
// create curl resource
$ch = curl_init();
// set url
curl_setopt($ch, CURLOPT_URL, "http://www.eastbay.com/shoppingcart/gateway?action=requestKey&_=");
//return the transfer as a string
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true );
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($ch, CURLOPT_COOKIEFILE, $cookies); // Send Cookies.
curl_setopt($ch, CURLOPT_COOKIEJAR, $cookies); // Receive Cookies.
// $output contains the output string
$output = curl_exec($ch);
// close curl resource to free up system resources
curl_close($ch);
// Decoding the json in to an array
$decoded = json_decode($output, true);
//using the array to get the data
echo "RequestKey: " . $decoded['data']['RequestKey'] . "<br>";
echo "Success: ". $decoded['success'] . "<br>";
//foreach loop because its an array which hold the errors, it wont output anything because there are no errors.
foreach($decoded['errors'] AS $error){
echo "Error: " . $error . "<br>";
}
?>
