php: loop through json array
(4 answers)
Closed 4 years ago.
I have a small issue that is driving me nuts.
Through a GET Request, I obtain a nice amount of json Data from google.
How in the world can I loop through it, in order to get only the ['videoID'] entries.
I would be really glad if someone could help me out on this.
$url ="https://www.googleapis.com/youtube/v3/playlistItems?part=snippet&maxResults=50&playlistId=UUyrB0KeB5pSGPajE0RVMoRA&key=AIzaSyDaLp92MtlcSnJjFVZYjoZIs7z5Wi_P-gQ";
$ch = curl_init();
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); // Disable SSL verification
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_URL,$url);
$result=curl_exec($ch);
curl_close($ch);
$json = json_decode($result,true);
print_r($json);
Please use below code:
$url ="https://www.googleapis.com/youtube/v3/playlistItems?part=snippet&maxResults=50&playlistId=UUyrB0KeB5pSGPajE0RVMoRA&key=AIzaSyDaLp92MtlcSnJjFVZYjoZIs7z5Wi_P-gQ";
$ch = curl_init();
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); // Disable SSL verification
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_URL,$url);
$result=curl_exec($ch);
curl_close($ch);
$json = json_decode($result,true);
$videoIds = array();
foreach($json['items'] as $item){
$videoIds[] = $item['snippet']['resourceId']['videoId'];
}
print_r($videoIds);
Hope this helps.

i know this has been asked many many times before,but this time should be the last time because the solution should be universaland unique that anyone can use the code anywhere in the project.
So the question : How to get any website header using curl in the same way as get_headers which produce an array.
I know i am answering my own question but because i have been working on the code myself.I was looking at some answers on stackoverflow and other websites,so i'm coming with simple code which give the universal and unique result.
I hope i don't have to explane it how to use the code because it's made by simple logic.
<?php
function curl_get_headers($base_url){
if(ini_get('allow_url_fopen')){
$result_header = get_headers($base_url);
}elseif(in_array('curl', get_loaded_extensions())){
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $base_url);
if(strpos($base_url,'https') !== false){
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
}
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_NOBODY, true);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($ch, CURLOPT_HEADER, true);
$response = curl_exec($ch);
curl_close($ch);
preg_match_all('/(.*)/',$response,$results);
foreach($results AS $result_key=>$result_array){
foreach($result_array AS $value){
if(strlen($value)>=10){
$string = preg_replace('/\s+$/','',$value);
$result[$result_key][] = $string;
}
}
}
$result_header = end($result);
}else{
/* Because we got this far, tell the user what to do! */
die('<h1 align="center">Server error : allow_url_fopen and curl is not enabled,<br />please ask your webhosting to enable one of the option!</h1>');
}
return $result_header;
}
?>
This really has me perplexed and other examples on Stackoverflow have not helped.
If I type into the browser :
https://api.bitfinex.com/v2/book/tXMRUSD/P0
I will get an long array of data which is correct.
With the following simple code :
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,"https://api.bitfinex.com/v2/book/tXMRUSD/P0");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_HTTPGET, 1);
$result = curl_exec($ch);
curl_close($ch);
var_dump($result);
I get :
bool(false)
The only difference is my browser fetches the data directly, while the PHP code is on a local website hosted using IIS on windows 10.
I've tried everything and just can't see where I'm going wrong. Any help will be most appreciated. (Ironically, all the authenticated and encrypted POST code works fine and I'm stuck on the easy stuff!)
Try This code it will work!!!!
<?php
$url= "https://api.bitfinex.com/v2/book/tXMRUSD/P0";
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
$result = curl_exec($ch);
curl_close($ch);
print_r($result);
?>
I have a task: get by inputed keyword Wikipedia article, save it to database and then make a search inside them.
The problem is: how to access api and retrieve data from wikipedia, I've tried this url (at the begining i've tried json format):
$url = 'https://en.wikipedia.org/w/api.php?action=query&titles=Dog&prop=revisions&rvprop=content&format=xml';
and this php code:
$ch=curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_USERAGENT, $_SERVER['HTTP_USER_AGENT']);
$res = curl_exec($ch);
if (!$res) {
echo 'cURL Error: '.curl_error($ch);
}
var_dump($res);
but nothing happend. Is it possible to access data with curl?
At the end one code worked with url above:
ini_set('user_agent','TestText');
$xmlDoc = new \DOMDocument();
$xmlDoc->load($url);
echo($xmlDoc->saveXML());
and then I get the text like this
{{about|the domestic dog|related species known as "dogs"|Canidae|other
uses|Dog (disambiguation)|}} {{Redirect|Doggie|the Danish
artist|Doggie (artist)}} {{pp-semi-indef}} {{pp-move-indef}} {{Taxobox
| name = Domestic dog | fossil_range = {{Fossil
range|0.033|0}}[[Pleistocene]] – [[Recent]] |
How can I handle it to be prettier (text with paragraphes or at liest plain text)?
So, There are two questions:
1. Is it possible to access wiki data with php curl and how I should improve my code?
2. How do I make wiki xml code prettier?
My question about code, especially about curl. Why it doesn't work?
And also, answer to another question says only about wikipedia api urls. By only changing url I can't solve problem.
I've found the solution, CURLOPT_SSL_VERIFYPEER was needed:
$url = 'http://en.wikipedia.org/w/api.php?action=query&prop=extracts&format=json&explaintext=&titles=Dog';
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, TRUE);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_USERAGENT, $_SERVER['HTTP_USER_AGENT']);
$res = curl_exec($ch);
//$json_data = mb_substr($res, curl_getinfo($ch, CURLINFO_HEADER_SIZE));
curl_close($ch);
$json = json_decode($res);
$content = $json->query->pages;
$wiki_id = '';
foreach ($content as $key => $value) {
$wiki_id = $key;
}
echo $content = $content->$wiki_id->extract;
I have 2 sites, one main, one external. On the main site, I am using Lucene to search through it. The problem is, I am trying to also search through the external site.
The Form action for the external site:
<form action="https://secure.bcchf.ca/SuperheroPages/searchResults.cfm?Event=WOT" method="post" name="search_tribute" >
I've tried to use curl, but it only brings up the search form without actually doing the search (the field is empty as well).
<?php
$ch = curl_init("https://secure.bcchf.ca/SuperheroPages/searchResults.cfm?Event=WOT");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, tname='hello');
$output = curl_exec($ch);
echo $output;
curl_close($ch);
?>
Any tips?
I don't have access to the form action since it's on an external site. All i have is a form that links to it when I submit it.
<?php
$ch = curl_init("https://secure.bcchf.ca/SuperheroPages/searchResults.cfm?Event=WOT");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, array("teamName" => "hello", "searchType" => "team"));
$output = curl_exec($ch);
echo $output;
curl_close($ch);
?>
Can you try this?
I'm pretty sure it's supposed to be teamName instead of tName
Most search engine use GET and not POST .. you can try
// asumption
$_POST['search'] = "hello";
// Return goole Search Result
echo curlGoogle($_POST['search']);
function curlGoogle($keyword) {
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'http://www.google.com/search?hl=en&q=' . urlencode($keyword) . '&btnG=Google+Search&meta=');
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_FILETIME, true);
$data = curl_exec($ch);
curl_close($ch);
return $data;
}
Or if you want post then
curl_setopt($ch, CURLOPT_POSTFIELDS, array("search"=>"hello"));
Your php code is not valid syntax, it does not compile.
So if this is really what you have, your problem is that your file generates a fatal error.
That being said, this question is hard to answer since we don't know the site you want to grab your search results from.
Try modifying your line like this:
curl_setopt($ch, CURLOPT_POSTFIELDS, "search=hello");
or alternatively
curl_setopt($ch, CURLOPT_POSTFIELDS, array("search" => "hello");
Maby it will work, however it may be that more post data is required or that the element name is not correct.
You have to look at the form or try making a request and look at it with chromes developer tools or firebug.
Also there are a number of ways for external sites to prevent what you are doing, altough evertything can be worked around somehow.
Assuming that is not the case, I hope i could help you.
Try just putting it into an array.
as that will be the variable the $_POST checks on the other side
and just checked your link, its teamName for the field
$fields = array("teamName"=>"julia");
Then..
curl_setopt($ch, CURLOPT_POSTFIELDS, $fields);
So your complete code is...
<?php
$ch = curl_init("https://secure.bcchf.ca/SuperheroPages/searchResults.cfm?Event=WOT");
$fields = array("teamName"=>"julia");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $fields);
$output = curl_exec($ch);
var_dump($output);
curl_close($ch);
?>

How to properly send and receive XML using curl?
(2 answers)
Closed 9 years ago.
I have fetched data from server using this code, `$server = 'LOCALHOST:9000';
$headers = array(
"Content-type: text/xml"
,"Content-length: ".strlen($requestXML)
,"Connection: close"
);
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $server);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_TIMEOUT, 100);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $requestXML);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
$data = curl_exec($ch);
if(curl_errno($ch)){
print curl_error($ch);
echo " something went wrong..... try later";
}else{
echo " request accepted";
print $data;
curl_close($ch);
}`
Now I have to do reverse, how to send the data into server using php? curl method is the only way or is there any other method to do the same. Give me some example.
Sending/Receiving using cURL is the exact same thing. cURL is based on sending data to an given URL and possibly receiving a response. Let's take a simple example of getting a user and sending a user.
Getting a user would be
$data = array(
'user_id' => 1
);
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "http://www.site.com/getUser.php");
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($data));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$response = curl_exec($ch);
curl_close($ch);
getUser.php does nothing more than search for a user and return the data found.
$response would possibly contain data of the user, perhaps just a text-response containing the name. A serialized PHP array, an XML response with a full user profile.. etc.
Inserting/Sending data
$data = array(
'user_name' => 'Joshua',
'user_email' => 'my#email.com'
);
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "http://www.site.com/addUser.php");
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($data));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$response = curl_exec($ch);
curl_close($ch);
addUser.php performs some validation of the fields and if validated inserts a user in the database
$response in this case does not contain the userdata (however: it's a possibility), but more likely the $response contains a result. An ok textresponse, a json/xml response or perhaps a '200 OK' header response
It's all basically the same. There is no difference in getting/sending data using cURL. It's all based on sending a request and in most cases do something with the outcome.
