I'm using php to decode dailymotion api for related videos but my code is not working.. If i replace "list" with any other word it works perfectly.. But i have to use the word list due to dailymotion api.. Anyone who can help?
$string='{"list":[
{
"duration": 233,
"id": "x2laq9v",
"thumbnail_480_url": "http://s1.dmcdn.net/JsC-U/x480-8Xl.jpg",
"title": "Heart Touch Mashup 2015 | Hindi latest Sad Songs | Very Sad Song"
},
{
"duration": 239,
"id": "x2laq9v",
"thumbnail_480_url": "http://s1.dmcdn.net/JsC-U/x480-8Xl.jpg",
"title": "title 2"
}
]}';
$json_a=json_decode($string,true);
// array method
foreach($json_a[list] as $p)
{
echo '
duration: '.$p[duration].'
<br>title: '.$p[title].'
<br><br>';
}
You have decoded the JSON string as an associative array. You need to access the elements by giving the key as a string. Otherwise, PHP will assume it as a constant.
So, change
foreach($json_a[list] as $p)
{
echo '
duration: '.$p[duration].'
<br>title: '.$p[title].'
<br><br>';
}
to
foreach($json_a["list"] as $p)
{
echo '
duration: '.$p["duration"].'
<br>title: '.$p["title"].'
<br><br>';
}
It should work fine, then.
Try to put quotes on the array :
foreach($json_a['list'] as $p)

I already did my research first, but some topics didn't solve my issue and some quite different from what issue I have. I have a JSON that didn't print out the entire data and as upon checking the culprit is the newline when it was a value (it is my first time knowing it, my bad).
<?php
$jsn = <<<_JSON
{
"name": "Editorial",
"links": "default",
"data": [
{
"Status": "Pending",
"Tags": "Documentation",
"Info": "all documentation to be ready by Friday"
},
{
"Status": "Published",
"Tags": "Pros and Cons Limits",
"Info": "documentations about-Realtime\n-Speed per sec\n-API Limit"
}
]
}
_JSON;
$data = json_decode($jsn, true);
$output= $data['links'];
echo $output;
It will not print any output as the \n was there. So I was planning to do in the future, if they tried to use a newline, I will just temporary change the \n to other characters and decode it back. And that's where I'm having a hard time.
As testing it wasn't working for me.. Converting it back and show in textarea.
$txt = "Documentations about%2Realtime%2Speed per sec%2API Limit";
$value = str_replace("%2", '\n', $txt);
$textArea = '<textarea rows="4">'.nl2br($value).'</textarea>';
echo $textarea;
//output
//documentations about\nRealtime\nSpeed per sec\nAPI Limit
If anyone can help me in your spare time, I really appreciate it.. Thanks in advance.
I am unable to fetch desired data of title, score from the json_decode array, I have tried all the ways which are already discussed in stackoverflow. Can anyone help me..
$myKEY = "xyz";
$url_req= 'google api request here';
$results= checkPageSpeed($url_req_d);
$googleapi = json_decode($results,true);
Google api send the data like this when var_dump($googleapi) and I need to fetch title and score values from the array. Please reply suggested code to extract title and score values i.e "xyz" and "73"
{
"kind": "pagespeedonline#result",
"id": "www xyz com/",
"responseCode": 200,
"title": "xyz",
"ruleGroups": {
"SPEED": {
"score": 73
}
},
"pageStats": {
"numberResources": 67,
"numberHosts": 15,
"totalRequestBytes": "9354",
"numberStaticResources": 48,
"htmlResponseBytes": "129210",
"textResponseBytes": "5647",
"cssResponseBytes": "142839",
"imageResponseBytes": "411466",
"javascriptResponseBytes": "635453",
"otherResponseBytes": "94639",
"numberJsResources": 17,
"numberCssResources": 6
}, .........
$googleapi['title'] and $googleapi['ruleGroups']['SPEED']['score'] should do the trick. Check the documentation for more information on how you can access elements from multidimensional arrays.
I am trying to retrieve information from a JSON file using JSONReader (I've implemented JSONReader to my PHP configuration) and I am trying to get the information from a simple JSON file (see below) about the whole part of the array (part, where Home Lawrence Library is) and I am struggling with this.
To be honest, I don't know how to use JSONReader properly.
This is my code:
inline <?php $reader = new JSONReader();
$reader->open('http://www.example.com/news.json');
while ($reader->read()) {
switch($reader->tokenType) {
case JSONReader::ARRAY_START:
echo "Array start:\n";
break;
case JSONReader::ARRAY_END:
echo "Array end.\n";
break;
case JSONReader::VALUE:
echo " - " . $reader->value . "\n";
break;
}
}
$reader->close();
?>
It is just printing array start and array end, but does not print the value.
JSON code:
{
"markers": [
{
"homeTeam": "Lawrence Library",
"awayTeam": "LUGip",
"markerImage": "images/red.png",
"information": "Linux users group meets second Wednesday of each month.",
"fixture": "Wednesday 7pm",
"capacity": "",
"previousScore": ""
},
{
"homeTeam": "Hamilton Library",
"awayTeam": "LUGip HW SIG",
"markerImage": "images/white.png",
"information": "Linux users can meet the first Tuesday of the month to work out harward and configuration issues.",
"fixture": "Tuesday 7pm",
"capacity": "",
"tv": ""
},
{
"homeTeam": "Applebees",
"awayTeam": "After LUPip Mtg Spot",
"markerImage": "images/newcastle.png",
"information": "Some of us go there after the main LUGip meeting, drink brews, and talk.",
"fixture": "Wednesday whenever",
"capacity": "2 to 4 pints",
"tv": ""
}
] }

Btw, I am trying to parse big JSON files so please do not suggest to use json_decode or curl methods.
I'm relatively new to mediawiki and has just started last week.
Anyone can point me to the correct direction of getting the top article (based on number of likes) in mediawiki? I've already implemented the fblikebutton extension on every article and managed to retrieve the number of likes for each article.
Code that I used to check the number of likes in each article on different URLS
$query_for_fql = "SELECT like_count FROM link_stat WHERE url = '".$full_url."'";
$fqlURL = "https://api.facebook.com/method/fql.query?format=json&query=" . urlencode($query_for_fql);
$response = file_get_contents($fqlURL);
$json_data = json_decode($response);
$fb_like_count = $json_data[0]->like_count;
echo 'Facebook Like:'.$fb_like_count .'<br/>';
eg:
example.com/wiki/index.php?title=ABC (1 like)
example.com/wiki/index.php?title=XYZ (2 likes)
I tried this but this is not working
$highest = 0;
while($highest < $fb_like_count)
{
if($fb_like_count > $highest) //if loop at first
{
$highest = $fb_like_count;
echo "highest value is " . $highest . '<br/>';
}
}
I want to retrieve the content in example.com/wiki/index.php?title=XYZ and display in the "Top Article Page". What should I do next after retrieving the number of likes for each article on each url. The extensions I found for top articles are based on the number of views. But I want to classify the top article based on number of likes.
Thanks a million for helping!
As I said in my comment to you question, FQL is deprecated, and the https://api.facebook.com/method/fql.query endpoint as well.
If you want something future-proof, then you should switch to the /?ids={url1},{url2},... endpoint. You can use this one to generate the comma-separated list of URLs inn the forehand, and then retrieve all the shares in one request, for example
GET /?ids=http://www.techcrunch.com,http://www.google.com
returns
{
"http://www.techcrunch.com": {
"og_object": {
"id": "433841427570",
"title": "TechCrunch",
"type": "website",
"updated_time": "2015-05-27T21:31:39+0000",
"url": "http://techcrunch.com/"
},
"share": {
"comment_count": 0,
"share_count": 20914
},
"id": "http://www.techcrunch.com"
},
"http://www.google.com": {
"og_object": {
"id": "381702034999",
"description": "Search the world's information, including webpages, images, videos and more. Google has many special features to help you find exactly what you're looking for.",
"title": "Google",
"type": "website",
"updated_time": "2015-05-28T07:10:18+0000",
"url": "http://www.google.com/"
},
"share": {
"comment_count": 2,
"share_count": 12340803
},
"id": "http://www.google.com"
}
}
The sorting issue you have is not related to the Facebook API, but PHP.
See
https://developers.facebook.com/docs/graph-api/reference/v2.3/url
Sort JSON object in PHP by a key value
How to sort JSON objects by a certain key's value
I am using PHP on shared server to access external site via API that is returning JSON containing 2 levels of data (Level 1: Performer & Level 2: Category array inside performer). I want to convert this to multidimensional associative array WITHOUT USING json_decode function (it uses too much memory for this usage!!!)
Example of JSON data:
[
{
"performerId": 99999,
"name": " Any performer name",
"category": {
"categoryId": 99,
"name": "Some category name",
"eventType": "Category Event"
},
"eventType": "Performer Event",
"url": "http://www.novalidsite.com/something/performerspage.html",
"priority": 0
},
{
"performerId": 88888,
"name": " Second performer name",
"category": {
"categoryId": 88,
"name": "Second Category name",
"eventType": "Category Event 2"
},
"eventType": "Performer Event 2",
"url": "http://www.novalidsite.com/somethingelse/performerspage2.html",
"priority": 7
}
]
I have tried to use substr and strip the "[" and "]".
Then performed the call:
preg_match_all('/\{([^}]+)\}/', $input, $matches);
This gives me the string for each row BUT truncates after the trailing "}" of the category data.
How can I return the FULL ROW of data AS AN ARRAY using something like preg_split, preg_match_all, etc. INSTEAD of the heavy handed calls like json_decode on the overall JSON string?
Once I have the array with each row identified correctly, I CAN THEN perform json_decode on that string without overtaxing the memory on the shared server.
For those wanting more detail about json_decode usage causing error:
$aryPerformersfile[ ] = file_get_contents('https://subdomain.domain.com/dir/getresults?id=1234');
$aryPerformers = $aryPerformersfile[0];
unset($aryPerformersfile);
$mytmpvar = json_decode($aryPerformers);
print_r($mytmpvar);
exit;
If you have a limited amount of memory, you could read the data as a stream and parse the JSON one piece at a time, instead of parsing everything at once.
getresults.json:
[
{
"performerId": 99999,
"name": " Any performer name",
"category": {
"categoryId": 99,
"name": "Some category name",
"eventType": "Category Event"
},
"eventType": "Performer Event",
"url": "http://www.novalidsite.com/something/performerspage.html",
"priority": 0
},
{
"performerId": 88888,
"name": " Second performer name",
"category": {
"categoryId": 88,
"name": "Second Category name",
"eventType": "Category Event 2"
},
"eventType": "Performer Event 2",
"url": "http://www.novalidsite.com/somethingelse/performerspage2.html",
"priority": 7
}
]
PHP:
$stream = fopen('getresults.json', 'rb');
// Read one character at a time from $stream until
// $count number of $char characters is read
function readUpTo($stream, $char, $count)
{
$str = '';
$foundCount = 0;
while (!feof($stream)) {
$readChar = stream_get_contents($stream, 1);
$str .= $readChar;
if ($readChar == $char && ++$foundCount == $count)
return $str;
}
return false;
}
// Read one JSON performer object
function readOneJsonPerformer($stream)
{
if ($json = readUpTo($stream, '{', 1))
return '{' . readUpTo($stream, '}', 2);
return false;
}
while ($json = readOneJsonPerformer($stream)) {
$performer = json_decode($json);
echo 'Performer with ID ' . $performer->performerId
. ' has category ' . $performer->category->name, PHP_EOL;
}
fclose($stream);
Output:
Performer with ID 99999 has category Some category name
Performer with ID 88888 has category Second Category name
This code could of course be improved by using a buffer for faster reads, take into account that string values may themselves include { and } chars etc.
You have two options here, and neither of them include you writing your own decoder; don't over-complicate the solution with an unnecessary work-around.
1) Decrease the size of the json that is being decoded, or
2) Increase the allowed memory on your server.
The first option would require access to the json that is being created. This may or may not be possible depending on if you're the one originally creating the json. The easiest way to do this is to unset() any useless data. For example, maybe there is some debug info you won't need, so you can do unset($json_array['debug']); on the useless data.
http://php.net/manual/en/function.unset.php
The second option requires you to have access to the php.ini file on your server. You need to find the line with something like memory_limit = 128M and make the 128M part larger. Try increasing this to double the value already within the file (so it would be 256M in this case). This might not solve your problem though, since large json data could still be the core of your problem; this only provides a work-around for inefficient code.
