I have the below function that works perfect when I put the URL string within the argument manually. I need it to be dynamic though and I am using Wordpress.
function get_tweets($url) {
$json_string = file_get_contents('http://urls.api.twitter.com/1/urls/count.json?url=' . $url);
$json = json_decode($json_string, true);
return intval( $json['count'] );
}
// Below is the one that works manually
<?php echo get_tweets('http://www.someurl.com');
//ones I have tried that do not (trying to make dynamic)
$url = $get_permalink();
echo get_tweets('$url');
echo get_tweets($url);
$url = '$get_permalink()';
$url = $get_permalink(); // produces needs to be in string error
echo get_tweets($url);
There is nothing wrong with what you're doing, per se. The only obvious mistake I can see is that you aren't encoding the URL properly. You need to ensure the query string arguments you put in the URL are properly URL encoded, otherwise the remote host may not interpret the request correctly.
function get_tweets($url) {
$json_string = file_get_contents('http://urls.api.twitter.com/1/urls/count.json?url=' . urlencode($url));
$json = json_decode($json_string, true);
return intval( $json['count'] );
}
echo get_tweets('http://www.someurl.com'); // should work just fine
Did you try to urlencode your url String?
urlencode($foo);
Your main problem is on below line
Change
//ones I have tried that do not (trying to make dynamic)
$url = $get_permalink();
To
//ones I have tried that do not (trying to make dynamic)
$url = get_permalink();

I'm trying to return a value from my API using PHP, api can be found here:
code is as follows:
Im not seeing the echo on my page, don't see any errors and I believing im reading the json in correctly. Any help appreciated!
<?php
$titleid = 2;
$url = "http://kmoffett07.lampt.eeecs.qub.ac.uk/serverSide/buildapi.php?id={$titleid}";
$response = file_get_contents($url);
$returnvalue = json_decode($response, true);
echo $returnvalue["Age"];
?>
From what I can tell, the json is not valid on the server side (due to the "connected to db" text in front of the {} part). I think it would be a good idea to fix the server side response json data, if possible!
For now, here is a way to get the value it looks like you are intending to retrieve:
<?php
$titleid = 2;
$url = "http://kmoffett07.lampt.eeecs.qub.ac.uk/serverSide/buildapi.php?id={$titleid}";
$response = file_get_contents($url);
$adjusted_response = str_replace('connected to db', '', $response);
$returnvalue = json_decode($adjusted_response, true);
echo $returnvalue['tv_shows']['Age'];
?>
Output:
$ php example.php
16+
If the server side json data is fixed, I think you could shorten the code to something like this:
<?php
$titleid = 2;
$url = "http://kmoffett07.lampt.eeecs.qub.ac.uk/serverSide/buildapi.php?id={$titleid}";
$response = file_get_contents($url);
$returnvalue = json_decode($response, true);
echo $returnvalue['tv_shows']['Age'];
?>
The thing is that $response is returned as string , in order to fix that you need to edit your backend and make it give the response without "connected to db"
I understand this may have been answered somewhere, but after looking and looking through numerous questions/answers and other websites, I'm unable to find a suitable answer.
I'm trying to create a page, which will show some video from Youtube. It will show the image, and title. I've managed to do both of these, although i'm having problems with the title. With the code i'm using, it is awfully slow at loading. I assume because of it loading the actual website just to get the title.
This is what i'm using to get the titles currently.
function get_youtube_id($url){
parse_str( parse_url( $url, PHP_URL_QUERY ), $my_array_of_vars );
return $my_array_of_vars['v'];
}
function get_youtube_title($video_id){
$url = "http://www.youtube.com/watch?v=".$video_id;
$page = file_get_contents($url);
$doc = new DOMDocument();
$doc->loadHTML($page);
$title_div = $doc->getElementById('eow-title');
$title = $title_div->nodeValue;
return $title;
}
So, how would the best way to get a youtube title by the id. The code I have does work, but it also makes the page load very very slow.
Thanks
Here is a simple way to do it using PHP and no library. YouTube already allows you to retrieve video detail information in the JSON format, so all you need is a simple function like this:
function get_youtube_title($ref) {
$json = file_get_contents('http://www.youtube.com/oembed?url=http://www.youtube.com/watch?v=' . $ref . '&format=json'); //get JSON video details
$details = json_decode($json, true); //parse the JSON into an array
return $details['title']; //return the video title
}
The function parameter being the video ID. You could also add a second parameter asking for a specific detail and change the function name so you could retrieve any data from the JSON that you would like.
EDIT:
If you would like to retrieve any piece of information from the returned video details you could use this function:
function get_youtube_details($ref, $detail) {
if (!isset($GLOBALS['youtube_details'][$ref])) {
$json = file_get_contents('http://www.youtube.com/oembed?url=http://www.youtube.com/watch?v=' . $ref . '&format=json'); //get JSON video details
$GLOBALS['youtube_details'][$ref] = json_decode($json, true); //parse the JSON into an array
}
return $GLOBALS['youtube_details'][$ref][$detail]; //return the requested video detail
}
If you request different details about the same video, the returned JSON data is stored in the $GLOBALS array to prevent necessary calls to file_get_contents.
Also, allow_url_fopen will have to be on in your php.ini for file_get_contents to work, which may be a problem on shared hosts.
You can use Open Graph
Checkout This Link
<?php
require_once('OpenGraph.php');
function get_youtube_title($video_id){
$url = "http://www.youtube.com/watch?v=".$video_id;
$graph = OpenGraph::fetch($url);
// You can get title from array
return $graph->title;
}
It's been 5 years, but my script bellow could be useful.
<?php
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "https://www.youtube.com/watch?v=YOUTUBEID");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$output = curl_exec($ch);
$document = htmlspecialchars($output);
curl_close($ch);
$line = explode("\n", $document);
$judul = "";
foreach($line as $strline){
preg_match('/\<title\>(.*?)\<\/title\>/s', $strline, $hasil);
if (!isset($hasil[0]) || $hasil[0] == "") continue;
$title = str_replace(array("<title>", "</title>"), "", $hasil[0]);
}
echo $title;
I am using CURL to send a URL. It's not sending an URL which contains PHP variables although is working perfectly on a defined URL (not incuding any PHP variable).
For example: This link is not working because of PHP variables :
$url = "http://abc/create/name/{$firstname} {$lastname}/email/{$email}/password/{$password1}?level={$level}&session=Dec";
$request = curl_init($url);
$response = curl_exec($request);
var_dump($response);
This works fine: Contains static values
$url = "http://abc/create/name/any one/email/anyone#gmail.com/password/12345?level=1&session=Dec";
$request = curl_init($url);
$response = curl_exec($request);
var_dump($response);
What am I doing wrong? Any leads?
Note: The URL is perfectly echoed, No error in echo $url
please putt like this and it will work
$url = 'http://abc/create/name/{'.$firstname.'}{'.$lastname.'}/email/{'.$email.'}/password/{'.$password1.'}?level={'.$level.'}&session=Dec"';
Finally got the solution :)
I am giving a space between in my {$firstname} {$lastname}thats why its not sending the URL.
So i just concatenate my firstname and lastname in a single variable and it works like a charm.
$fullname = $get_user_firstname.$get_user_lastname;
$fullname = urlencode($fullname);
$url = "http://abc/create/name/{$fullname}/email/{$email}/password/{$password1}?level={$level}&session=Dec";
Hope anyone with similar issue can get help from my this answer that's why i posted it. cheers!
(I'm scraping this stuff with the permission of the website in question, by the way).
Pretty simple web scraper, was working fine when I was loading all the links by hand, but when I've tried to load them in via JSON and variables (so I can do lots of scraping with the one script and make the process more modular by just adding more links to JSON) it runs on an infinite loop.
(Page has been loading for about 15 minutes now)
Here is my JSON. Only one store is in there for testing purposes but there is going to be about 15 more.
[
{
"store":"Incu Men",
"cat":"Accessories",
"general_cat":"Accessories",
"spec_cat":"accessories",
"url":"http://www.incuclothing.com/shop-men/accessories/",
"baseurl":"http://www.incuclothing.com",
"next_select":"a.next",
"prod_name_select":".infobox .fn",
"label_name_select":".infobox .brand",
"desc_select":".infobox .description",
"price_select":"#price",
"mainImg_select":"",
"more_imgs":".product-images",
"product_url":".hproduct .photo-link"
}
]
Here is the PHP scraper code:
<?php
//Set infinite time limit
set_time_limit (0);
// Include simple html dom
include('simple_html_dom.php');
// Defining the basic cURL function
function curl($url) {
$ch = curl_init();
// Initialising cURL
curl_setopt($ch, CURLOPT_URL, $url);
// Setting cURL's URL option with the $url variable passed into the function
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
// Setting cURL's option to return the webpage data
$data = curl_exec($ch);
// Executing the cURL request and assigning the returned data to the $data variable
curl_close($ch);
// Closing cURL
return $data;
// Returning the data from the function
}
function getLinks($catURL, $prodURL, $baseURL, $next_select) {
$urls = array();
while($catURL) {
echo "Indexing: $url" . PHP_EOL;
$html = str_get_html(curl($catURL));
foreach ($html->find($prodURL) as $el) {
$urls[] = $baseURL . $el->href;
}
$next = $html->find($next_select, 0);
$url = $next ? $baseURL . $next->href : null;
echo "Results: $next" . PHP_EOL;
}
return $urls;
}
$string = file_get_contents("jsonWorkers/incuMens.json");
$json_array = json_decode($string,true);
foreach ($json_array as $value){
$baseURL = $value['baseurl'];
$catURL = $value['url'];
$store = $value['store'];
$general_cat = $value['general_cat'];
$spec_cat = $value['spec_cat'];
$next_select = $value['next_select'];
$prod_name = $value['prod_name_select'];
$label_name = $value['label_name_select'];
$description = $value['desc_select'];
$price = $value['price_select'];
$prodURL = $value['product_url'];
if (!is_null($value['mainImg_select'])){
$mainImg = $value['mainImg_select'];
}
$more_imgs = $value['more_imgs'];
$allLinks = getLinks($catURL, $prodURL, $baseURL, $next_select);
}
?>
Any ideas why the script would be running infinitely and not returning anything/stopping/printing anything to screen? I'm just gonna let it run until it stops. When I was doing this by hand it would only take a minute or so, sometimes less, so I'm sure it's a problem with my variables/json but I can't for the life of me see what the issues lie.
Can anyone take a quick look and point me in the right direction?
There is a problem with your while($catURL) loop. What do you want to do ?
Moreover, you can force to display information on your browser with the flush() command.
I am very new to PHP, and need to use an HTTP Request to download a URL that is external to my server. That URL is a PHP function that returns JSON code which I have decode. Any suggestions?
I have tried basic code:
<?php
//Code for forming the url (which I'm sure is correct)
$url = ...
$response = fopen($url,"x+");
$response = json_decode($response);
echo $response;
?>
//javascript in a seperate file that calls the php code
var response = xmlhttp.responseText;
alert(response);
Try this:
<?php
$url = 'YOUR_URL_HERE';
$data = file_get_contents( $url ); // it is a JSON response as per your statement.
$data= json_decode($data);
print_r($data); // now, it's a normal array.
?>
You may use fopen if config allows, or cURL or fsockopen functions to do that
You could use:
$json_str = file_get_contents($url);
$json = json_decode($json_str, true);
Couldn't you use file_get_contents? E.g.
<?php
$url = "YOUR_URL";
$json = file_get_contents($url);
// handle the data
$data = json_decode($json, TRUE);
var_dump($data); // example
?>
