I am trying to get title of the webpage, see the code below..
include("simple_html_dom.php");
$url = "http://fzmoviez.in/video/list/4059539";
$base = $url;
$curl = curl_init();
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, FALSE);
curl_setopt($curl, CURLOPT_HEADER, false);
curl_setopt($curl, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($curl, CURLOPT_URL, $base);
curl_setopt($curl, CURLOPT_REFERER, $base);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, TRUE);
$str = curl_exec($curl);
curl_close($curl);
// Create a DOM object
$html_base = new simple_html_dom();
// Load HTML from a string
$html_base->load($str);
$title = $html_base->getElementsByTagName("title")->innertext; //line 21
echo $title;
I am getting error:
Notice: Trying to get property of non-object in C:\xampp\htdocs\... on line 21
but when I var_dump($html_base) I get
object(simple_html_dom)#1 (23) { ["root"]=> object(simple...
... card" ["attr"]=> array(2) { ["id"]=> string(5) "index" ["title"]=> string(179) "FzMoviez.iN - Free Download Latest Bollywood Movies,Hindi Dudded Movies,Hollywood Movies,Live Movies,WWE Shows,Mp4,HD Mp4,High Quality Mp4,Avi,Iphone,Android,Tablets And Many More" } ["children"]=> array(25) { [0]=> object(simple_html_dom_node)#55 (9) { ["nodetype"]=>......
meaning, it is an object, and title is there, why giving error
Notice: Trying to get property of non-object in C:\xampp\htdocs\.. on line 21
$html_base->getElementsByTagName("title")
Will return array of elements, you need to iterate through this array to get your data.

Hello may i know how to retrieve data in string?
$url = 'test url';
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$info = curl_getinfo($ch);
$response = curl_exec($ch);
curl_close ($ch);
echo 'Response: ';
echo gettype($response);
echo '<br>';
echo($response);
Output :
Response: string
TRANSACTION_ID=abc123
MERCHANT_ACC_NO=M213213
TXN_STATUS=A
TRAN_DATE=2020-07-20
CAPTURE_DATE=2020-07-20
SALES_DATE=2020-07-20
RESPONSE_CODE=1
RESPONSE_MESSAGE=Success
As you can see the output of the code is as shown above. This is my first time to encounter this kind of output because usually I get json as the output. So my question is may I know how to retrieve the RESPONSE_MESSAGE in the output or may I know how to convert the output to array or json so that I can easily retrieve the data. Sorry for asking this I'm quite new with this PHP and CURL function.
You can explode to lines and explode the lines to parts in a foreach.
Edit: I realized the "Response:" was actually outputted manually.
Changed the code to slice the array from second item instead.
foreach(array_slice(explode("\n", $str), 1) as $line){
$temp = explode("=", $line);
$res[$temp[0]] = $temp[1];
}
Output:
array(8) {
["TRANSACTION_ID"]=>
string(6) "abc123"
["MERCHANT_ACC_NO"]=>
string(7) "M213213"
["TXN_STATUS"]=>
string(1) "A"
["TRAN_DATE"]=>
string(10) "2020-07-20"
["CAPTURE_DATE"]=>
string(10) "2020-07-20"
["SALES_DATE"]=>
string(11) "2020-07-20 "
["RESPONSE_CODE"]=>
string(1) "1"
["RESPONSE_MESSAGE"]=>
string(7) "Success"
}

I am trying to post Facebook Page status as page(not user) through my script. This returns me an error 100.
Here I am generating temporary user_access_token from Graph Explorer with permission : manage_pages, publish_pages
Code:
<?php
$url='https://graph.facebook.com/v2.3/{$user_id}/accounts?access_token=USER_ACCESS_TOKEN';
$ch=curl_init();
CURL_SETOPT($ch,CURLOPT_URL,$url);
CURL_SETOPT($ch,CURLOPT_RETURNTRANSFER, 1);
$json=json_decode(curl_exec($ch));
$page_access_token=$json->data['0']->access_token;
curl_close($ch);
$page_id='xxx';
$message='helloworld';
$url="https://graph.facebook.com/v2.3/{$page_id}?access_token=$page_access_token";
$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, $url);
curl_setopt($curl, CURLOPT_POST, true);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($curl, CURLOPT_POSTFIELDS, $message);
curl_setopt($curl, CURLOPT_TIMEOUT, 10);
$result = json_decode(curl_exec($curl));
var_dump($result);
?>
If everything goes well, a string "helloworld" should get posted on Facebook page. But here it is returning with an error :
object(stdClass)#5 (1) {
["error"]=>
object(stdClass)#6 (3) {
["message"]=>
string(61) "(#100) Parameters do not match any fields that can be updated"
["type"]=>
string(14) "OAuthException"
["code"]=>
int(100)
}
}
What is mistake here ? Thank you.
You're trying to post to /<PAGE_ID>
The correct endpoint for creating a post on a Page is /<PAGE_ID>/feed, documented here: https://developers.facebook.com/docs/graph-api/reference/v2.3/page/feed
A valid format for a basic call to create a post would be https://graph.facebook.com/v2.3/<PAGE_ID>/feed?message=helloworld&access_token=<ACCESS_TOKEN>
I'm trying to parse a JSON answer from Redmine API and I don't know how to get to the parts of the array.
Here is the code:
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,'http://login:password#redmine.server/redmine/issues.json?cf_2=12345');
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-type: application/json'));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$response = curl_exec($ch);
$data = json_decode($response);
When I make a var_dump($data), the answer looks like this:
array(1) { [0]=> object(stdClass)#1853 (14) { ["id"]=> int(96) ["project"]=> object(stdClass)#1852 (2) { ["id"]=> int(68) ["name"]=> string(7) "Test.......
So, when I make a for loop, I would like to access the parts of the array:
foreach($data as $issues){
var_dump($issues["id"]);
}
And so on. Any idea on this?
Stupid me...
The culprit was here:
$data = json_decode($response);
Should be:
$data = json_decode($response,true);
Now I get a proper PHP array.
So i have a small PHP script to generate short links, it work but some times i got this error :
Undefined property: stdClass::$id","file":ShortLink.php","line":31
This is my script :
<?php
class ShortLink {
public static function generateShortLink($longUrl)
{
//This is the URL you want to shorten
$apiKey = 'MY_API_KEY';
//Get API key from : http://code.google.com/apis/console/
$postData = array('longUrl' => $longUrl, 'key' => $apiKey);
$jsonData = json_encode($postData);
$curlObj = curl_init();
curl_setopt($curlObj, CURLOPT_URL, 'https://www.googleapis.com/urlshortener/v1/url');
curl_setopt($curlObj, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($curlObj, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($curlObj, CURLOPT_HEADER, 0);
curl_setopt($curlObj, CURLOPT_HTTPHEADER, array('Content-type:application/json'));
curl_setopt($curlObj, CURLOPT_POST, 1);
curl_setopt($curlObj, CURLOPT_POSTFIELDS, $jsonData);
$response = curl_exec($curlObj);
//change the response json string to object
$json = json_decode($response);
curl_close($curlObj);
return $json->id;
}
}
When i start worked with this script 6 or 7 months ago i hadn't this error but now i start get it and i have no idea why, so please if someone has any idea i will be very appreciative.
Update :
When i vardump my $json i get that :
{ ["domain"]=> string(11) "usageLimits" ["reason"]=> string(26) "userRateLimitExceededUnreg" ["message"]=> string(40) "User Rate Limit Exceeded. Please sign up" ["extendedHelp"]=> string(36) "https://code.google.com/apis/console" } } ["code"]=> int(403) ["message"]=> string(40) "User Rate Limit Exceeded. Please sign up" }}
So i wondered if Google limited the Google shorten service ?
class ShortLink {
public static function generateShortLink($longUrl)
{
//This is the URL you want to shorten
$apiKey = 'YOUR_SERVER_API_KEY';
//Get API key from : http://code.google.com/apis/console/
$postData = array('longUrl' => $longUrl, 'key' => $apiKey);
$jsonData = json_encode($postData);
$curlObj = curl_init();
curl_setopt($curlObj, CURLOPT_URL, 'https://www.googleapis.com/urlshortener/v1/url');
curl_setopt($curlObj, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($curlObj, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($curlObj, CURLOPT_HEADER, 0);
curl_setopt($curlObj, CURLOPT_HTTPHEADER, array('Content-type:application/json'));
curl_setopt($curlObj, CURLOPT_POST, 1);
curl_setopt($curlObj, CURLOPT_POSTFIELDS, $jsonData);
$response = curl_exec($curlObj);
//change the response json string to object
$json = json_decode($response);
curl_close($curlObj);
if(!is_object($json))
{
return(false);
}
return $json->id;
}
}
$api = new ShortLink();
$shorturlid=$api->generateShortLink('http://avecsrthgdgnb.avcd');
echo $shorturlid;
are you using new console then enable URL Shortener API.
Sometimes because of network curl is not returned with response within 30 seconds (default time limit in php for a cmd to finish)
Try changing the time limit in php.ini or if that is not in your control or you do not want to modify it for all the php cmds try bool set_time_limit ( int $seconds ) before calling curl_exec
Update:
I see there is no id field in the json that is returned.
{ ["domain"]=> string(11) "usageLimits"
["reason"]=> string(26) "userRateLimitExceededUnreg"
["message"]=> string(40) "User Rate Limit Exceeded. Please sign up"
["extendedHelp"]=> string(36) "https://code.google.com/apis/console"
}
}
["code"]=> int(403)
["message"]=> string(40) "User Rate Limit Exceeded. Please sign up"
}
}
And if you closely see your User rate limit has been reached See here for details on limitation on using google apis. (You may try different IP i.e. different machine or different api key and same code may start working).
Hope this helps
I am using cURL to get json information from a site that pulls a random tumblr picture from a list of sources and I am interested of putting the json data retrieved into php variables so I can call for example, just the image url
$url = "http://someurl.com";
$ch = curl_init();
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_URL,$url);
$a = curl_exec($ch);
$json = var_dump(json_decode($a, true));
I get:
array(3) {
'image' =>
array(1) {
[0] =>
string(62) "http://picture.jpg"
}
'source' =>
string(31) "http://source.tumblr.com"
'page' =>
string(9) "/page/164"
}
What would I now do in order to just print the url for the image?
I have tried
$url = $json["image"][0];
and then calling $url, but it gives me nothing in return. What I am doing wrong?
I have never worked with json before so I am at a loss here, any help is appreciated!
according to code looks:-
try
change
$json = var_dump(json_decode($a, true));
to
$json = json_decode($a, true);
