So I have this api: http://85.17.32.4:8707/status-json.xsl
And I want to extract a few things from it, so I started off really basic:
<?php echo json_decode('http://85.17.32.4:8707/status-json.xsl');
It gave absolutely no result. Next try:
<?php
$var = json_decode('http://85.17.32.4:8707/status-json.xsl');
var_dump($var);
It just retourned NULL.
Then I tried making a cURL function:
<?php
$url = 'http://85.17.32.4:8707/status-json.xsl';
$ch = curl_init();
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_URL,$url);
$result=curl_exec($ch);
curl_close($ch);
var_dump(json_decode($result, true));
This also returned NULL. Do I have any further options?
Thanks.
Yes, you do have further options: check json_last_error_msg and see whether there was an issue with the json decoding:
$json = json_decode($result, true);
# check if there has been an error decoding:
if (! isset($json)) {
echo "Decoding error: " . json_last_error_msg() . PHP_EOL;
}
Output:
Decoding error: Syntax error
i.e. there is a syntax error in the JSON. You need to tell the JSON provider that they are not providing valid JSON.

Basically I'm trying to GET an API that gives me a JSON array. It should only be one integer. Whenever I try to though I receive the error:
Notice: Trying to get property of non-object in /public_html/call.php on line 16
Here's call.php:
<?php
require 'connection.php';
$players2weeks = '(removed api)';
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $players2weeks);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
$response = curl_exec($ch);
curl_close($ch);
$response = json_decode($response);
print_r($response);
echo $response->players_2weeks;
?>
I have the print_r for troubleshooting but I'm getting nothing. My apologies for a noob question by the way, I have no experience with JSON.
Appreciate the help!
I think you can use this Code :
<?php
require 'connection.php';
$players2weeks = '(removed api)';
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $players2weeks);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
$response = curl_exec($ch);
curl_close($ch);
$responses = json_decode($response);
print_r($responses);
echo $responses['players_2weeks'];
?>
You should change the format of echo when the decoded JSON objects. and the Variable same means some clashes in the print so I changed the $response variable also...
You have to make array to json string by using the json_encode() function on the api.
For example: xxx.php (api)
$result = array(); //return array
echo json_encode($result);
Then you can get result by json array on the api caller.
var_dump(json_decode($result)); // Object
var_dump(json_decode($result, true)); // Associative array
I am using file_get_contents to get the json from URLs. The same URL works sometimes and sometimes it doesn't. When it doesn't, file_get_contents does not return any error and just stops the whole script. It's too confusing.
What's error you get? It's warning or Fatal Error?
if it's warning, please add # to befor file_get_contents like: #file_get_contents
if other, please check data before execute other process
$jsondata =#file_get_contents('YOur URl');
if($jsondata){
// Process your code
}else{
//do nothing
}
What a URL is returning when the correct data is not outputted ?
1)
$json_data =file_get_contents('URl');
if($json_data){
//parse the data
}else{
//show error
}
2 to find what exactly the url returns
$json_data =file_get_contents('URl');
var_dump($json_data);
3 use cURL
$ch = curl_init();
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_URL, 'url_here');
$result = curl_exec($ch);
curl_close($ch);
$obj = json_decode($result);
var_dump($obj)
I wanted to try to get data from a JSON string which is loaded from another page. I currently have used Curl to get the data from the webpage but I can't acces the data in it.
I've already tried:
var_dump(json_decode($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.
I'm trying to connect to this webpage of the steam api. The market_hash_name parameter is the item I want to search. And as you can see, the response is in the format json. My code is this one:
$url = "http://steamcommunity.com/market/priceoverview/?currency=1&appid=730&market_hash_name=" . urlencode($hash_name);
$ch = curl_init();
$timeout = 10;
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, $timeout);
$data = curl_exec($ch);
curl_close($ch);
$data = json_decode($data, true);
if ($data['success'] == true) {
echo $url . "<br>";
echo "Data Found: " . $data;
} else {
"Data not found";
}
Sometimes I get the correct response and everything, but sometimes I get this characters <Ê+ÍÉÿÿOüË% as the $data variable. But it still gets inside the if! So it does have the 'success' key in that JSON response, although it's not readable.
EDIT: So I've seen that sometimes the url decides to return null instead of the JSON response. I think I get this weird characters when I get the null return. But this doesn't explain why It enters to the if sentence :/
You need add this to your CURL:
curl_setopt($ch, CURLOPT_ENCODING, '');
See the explanation here : PHP curl returning strange characters
Im stumbling upon issues I find hard to explain myself. I have this code that usually works perfectly fine, but after I change to nested information the result always lead to Fatal error: Cannot use string offset as an array. Even if I revert everything to the old state, it keeps telling me the fatal error. I am using the RIOT API (league of legends).
<?php
ini_set("display_errors", "1"); error_reporting(E_ALL);
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'https://euw.api.pvp.net/api/lol/euw/v2.5/league/challenger?type=RANKED_SOLO_5x5&api_key=key');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
$response = curl_exec($ch);
curl_close($ch);
$json = json_decode($response, true);
foreach($json as $elem)
{
echo $elem[0]['entries'][0]['playerOrTeamName'];
// echo $elem[0]['entries'][0]['miniSeries'][0]['wins'];
// echo $elem[0]['entries'][0]['miniSeries'][0]['losses'];
}
?>
You have not explored array properly.
foreach ($json['entries'] as $entry)
{
echo $entry['playerOrTeamName'] . ' wins:' . $entry['wins'] . "<br/>";
}
Also, your array does not contain losses, and miniSeries.
Please, explore your data thoroughly further.
