Sending data from Mysql with Json using PHP - php

I am trying to send data from a Mysql database using Json. As long as it is only 1 post in the database it works, but when its more rows its nor working anymore.
Here is the PHP code:
// array for JSON response
$response = array();
$data = new CDatabaseInfo();
$result = $data ->selectAll();
$data->closeDatabase();
// check for empty result
if (isset($result)) {
$response["products"] = array();
foreach($result as $value) {
$product = null;
$product = array();
$product["pid"] = $value["pid"];
$product["name"] = $value["name"];
$product["price"] = $value["price"];
$product["description"] = $value["description"];
$product["created_at"] = $value["created_at"];
$product["updated_at"] = $value["updated_at"];
array_push($response["products"], $product);
}
// success
$response["success"] = 1;
echo json_encode($response, TRUE);
echo "var dump <br>";
var_dump($response);
}
Here comes the result of var_dump:
array(2) { ["products"]=> array(2) {[0]=> array(6) { ["pid"]=> string(1) "1" ["name"]=> string(6) "Festis" ["price"]=> string(5) "20.00" ["description"]=> string(9) "God dryck" ["created_at"]=> string(19) "2015-07-09 20:31:30" ["updated_at"]=> string(19) "0000-00-00 00:00:00" } [1]=> array(6) { ["pid"]=> string(1) "4" ["name"]=> string(4) "Cola" ["price"]=> string(5) "12.00" ["description"]=> string(11) "En fin läsk" ["created_at"]=> string(19) "2015-07-20 20:29:03" ["updated_at"]=> string(19) "0000-00-00 00:00:00" } } ["success"]=> int(1) }
Thanks!

There is no such thing as json_encode($response, TRUE);
Be sure you get the right data from the database. Beside the little error, your code should run correctly.

Please help me to solve this issue.thanks
For first one you need to do:-
<?php
$token="<token>";
$data = file_get_contents("https://graph.facebook.com/106097030098624/photos?fields=id&access_token=$token");
$json = json_decode($data);
foreach($array.data as $arr){
echo $arr.id; echo PHP_EOL; // you can use `echo "<br/>";`
echo $arr.created_time;echo PHP_EOL;// you can use `echo "<br/>";`
}
?>
For second-one you can use:-
<?php
$token="<token>";
$data = file_get_contents("https://graph.facebook.com/106097030098624/photos?
fields=id&access_token=$token");
$array = json_decode($data, true);
foreach($array['data'] as $arr){
echo $arr['id']; echo PHP_EOL; // you can use `echo "<br/>";`
echo $arr['created_time'];echo PHP_EOL;// you can use `echo "<br/>";`
}
?>

Foreach mysql query from array, then a second query from that first array

Im trying to loop through a query from the result of another query:
public static function getActivityFromUsers()
{
$database = DatabaseFactory::getFactory()->getConnection();
// FETCH USER_ID FOR THE SECOND QUERY
$sql = "SELECT user_id, follower_since_timestamp FROM users_followers where follower_id = :user_id";
$query = $database->prepare($sql);
$query->execute(array(':user_id' => Session::get('user_id')));
if ($query->rowCount() <= 0) {
echo 'Nothing';
return false;
}
$_MYSQL_DATA = $query->fetchAll();
/* Just for my own testing and troubleshoot */
foreach ($_MYSQL_DATA as $row) {
echo $row->user_id . " - " . date('d/m/Y H:i:s', $row->follower_since_timestamp) ."<br/>";
}
echo var_dump($_MYSQL_DATA).'<br><br>';
/* End for my own testing and troubleshoot*/
// USING THE USER_ID´s FROM THE FIRST QUERY TO FETCH DATA FOR OUTPUT
foreach ($_MYSQL_DATA as $row) {
$sql = "SELECT activity, user_id, activity_timestamp FROM user_activity WHERE user_id = :user_id";
$query = $database->prepare($sql);
$query->execute(array(':user_id' => $row->user_id));
$new_data[] = $query->fetchAll();
}
// FOREACH TO OUTPUT DATA FROM SECOND QUERY (SHOULD BE ORDERD BY activity_timestamp)
foreach($new_data as $key => $object){
echo 'User_id: ' . $object->user_id.'<br>';
echo 'What: ' . $object->activity .'<br>';
echo 'When: ' . date('d/m/Y H:i:s', $object->activity_timestamp) .'<br>';
}
echo var_dump($new_data);
}
But this gives me the error: Notice: Trying to get property of non-object in .. User_id: etc..
The var_dump of $new_data[] (from the second query that fetched the data) gives me this: (notice the two arrays in the bottom, why is that? array[2] & array[3])
array(4) {
[0]=> array(7) {
[0]=> object(stdClass)#7 (3) { ["activity"]=> string(15) "Wrote" ["user_id"]=> string(1) "2" ["activity_timestamp"]=> string(10) "1433704851" }
[1]=> object(stdClass)#17 (3) { ["activity"]=> string(15) "Wrote" ["user_id"]=> string(1) "2" ["activity_timestamp"]=> string(10) "1433832032" }
[2]=> object(stdClass)#18 (3) { ["activity"]=> string(15) "Wrote" ["user_id"]=> string(1) "2" ["activity_timestamp"]=> string(10) "1433832033" }
[3]=> object(stdClass)#19 (3) { ["activity"]=> string(15) "Wrote" ["user_id"]=> string(1) "2" ["activity_timestamp"]=> string(10) "1433832035" }
[4]=> object(stdClass)#20 (3) { ["activity"]=> string(7) "Follows" ["user_id"]=> string(1) "2" ["activity_timestamp"]=> string(10) "1433832150" }
[5]=> object(stdClass)#21 (3) { ["activity"]=> string(7) "Wrote" ["user_id"]=> string(1) "2" ["activity_timestamp"]=> NULL }
[6]=> object(stdClass)#22 (3) { ["activity"]=> string(8) "Wrote " ["user_id"]=> string(1) "2" ["activity_timestamp"]=> NULL } }
[1]=> array(1) {
[0]=> object(stdClass)#16 (3) { ["activity"]=> string(19) "Finally!" ["user_id"]=> string(1) "3" ["activity_timestamp"]=> string(10) "1433794873" } }
[2]=> array(0) { }
[3]=> array(0) { } }
How do I properly foreach the result from the second query?
fetchAll returns an Array, not an object.
Replace all your
$object->xxx
by
$object['xxx']
Why not just use a single query..
SELECT
users_followers.user_id,
users_followers.follower_since_timestamp,
a.activity,
a.user_id,
a.activity_timestamp
FROM
users_followers
LEFT JOIN
(SELECT activity, user_id, activity_timestamp FROM user_activity) a
ON a.user_id = users_followers.user_id
where
users_followers.follower_id = :user_id

simplexml_load_string - child nodes not showing

I am working with an xml file that I am trying to parse into json format and then decode to an array. I accomplished this mainly using the built in simplexml_load_string and then json_encode. The issue is when calling simplexml_load_string the xml isn’t fully preserved. It seems like the child nodes for video show as object(stdClass). How could I get all values of the xml file? Link to XML
Code:
$xml = simplexml_load_string( file_get_contents('http://foxsoccer2go.mobilefeeds.performgroup.com/fox/api/videos.xml/channel/home') );
$json = json_encode($xml);
Result:
["results"]=>
object(stdClass)#183 (4) {
["previousPage"]=>
object(stdClass)#184 (1) {
["#attributes"]=>
object(stdClass)#185 (1) {
["exists"]=>
string(5) "false"
}
}
["nextPage"]=>
string(1) "2"
["total"]=>
string(2) "40"
["resultList"]=>
object(stdClass)#186 (1) {
["video"]=>
array(20) {
[0]=>
object(stdClass)#187 (7) {
["#attributes"]=>
object(stdClass)#188 (2) {
["id"]=>
string(7) "2329124"
["type"]=>
string(3) "960"
}
["description"]=>
object(stdClass)#189 (0) {
}
["created"]=>
string(25) "2015-02-18 04:04:52 +0000"
["duration"]=>
string(2) "86"
["images"]=>
object(stdClass)#190 (2) {
["image"]=>
object(stdClass)#191 (1) {
["#attributes"]=>
object(stdClass)#192 (3) {
["id"]=>
string(8) "13503818"
["width"]=>
string(3) "100"
["height"]=>
string(3) "100"
}
}
["thumbnail"]=>
object(stdClass)#193 (1) {
["#attributes"]=>
object(stdClass)#194 (3) {
["id"]=>
string(8) "13503819"
["width"]=>
string(3) "372"
["height"]=>
string(3) "210"
}
}
}
["videoFiles"]=>
object(stdClass)#195 (1) {
["file"]=>
object(stdClass)#196 (1) {
["#attributes"]=>
object(stdClass)#197 (3) {
["id"]=>
string(8) "14704560"
["formatId"]=>
string(3) "400"
["uploaded"]=>
string(4) "true"
}
}
}
["categories"]=>
object(stdClass)#198 (1) {
["category"]=>
string(21) "UEFA Champions League"
}
}
I would suggest just try to parse those values using SimpleXML alone and stick with it. Just access those properties properly. As for those nodes which have been wrapped with character data in it, cast them as (string).
$xml = simplexml_load_string( file_get_contents('http://foxsoccer2go.mobilefeeds.performgroup.com/fox/api/videos.xml/channel/home'));
foreach($xml->results->resultList->video as $video) {
$description = (string) $video->description;
$created = $video->created;
$duration = $video->duration;
$image = $video->images->image;
$thumbnail = (string) $video->images->image;
$video_file = (string) $video->videoFiles->file;
$categories = (string) $video->categories->category;
echo "
Description: $description <br/>
Created: $created <br/>
Duration: $duration <br/>
Categories: $categories <br/>
<hr/>
";
}

Converting Json String into PHP array then using php array

Im new to json & php and I'm having some issues with json into php string
My json string looks like this
{"status":"OK","cards":
[{"id":100001,"name":"batman","image":11111,"size":75,"region_id":1,"locked":false,"status":"active","created_at":"2013-08-15T11:37:07Z"},
{"id":100002,"name":"superman","image":111111,"size":75,"region_id":1,"locked":false,"status":"active","created_at":"2013-08-15T12:30:09Z"},
{"id":100003,"name":"catwoman","image":1111111,"size":75,"region_id":1,"locked":false,"status":"active","created_at":"2013-08-15T12:39:42Z"},
{"id":100004,"name":"bane","image":1111111,"size":75,"region_id":1,"locked":false,"status":"active","created_at":"2013-09-08T12:56:04Z"}
]}
So Far i have created my string
$json_raw = '{"status":"OK","cards": [{"id":100001,"name": .....
Decoded the json
$arr = json_decode($json_raw, TRUE);
I var_dump($arr);
then it returns
array(2) { ["status"]=> string(2) "OK" ["cards"]=> array(4) { [0]=> array(8) { ["id"]=> int(100001) ["name"]=> string(6) "batman" ["image"]=> int(11111) ["size"]=> int(75) ["region_id"]=> int(1) ["locked"]=> bool(false) ["status"]=> string(6) "active" ["created_at"]=> string(20) "2013-08-15T11:37:07Z" } [1]=> array(8) { ["id"]=> int(100002) ["name"]=> string(8) "superman" ["image"]=> int(111111) ["size"]=> int(75) ["region_id"]=> int(1) ["locked"]=> bool(false) ["status"]=> string(6) "active" ["created_at"]=> string(20) "2013-08-15T12:30:09Z" } [2]=> array(8) { ["id"]=> int(100003) ["name"]=> string(8) "catwoman" ["image"]=> int(1111111) ["size"]=> int(75) ["region_id"]=> int(1) ["locked"]=> bool(false) ["status"]=> string(6) "active" ["created_at"]=> string(20) "2013-08-15T12:39:42Z" } [3]=> array(8) { ["id"]=> int(100004) ["name"]=> string(4) "bane" ["image"]=> int(1111111) ["size"]=> int(75) ["region_id"]=> int(1) ["locked"]=> bool(false) ["status"]=> string(6) "active" ["created_at"]=> string(20) "2013-09-08T12:56:04Z" } } }
Now all I want to do is be able to use this data
e.g if name = batman then
I know this is a stupid question but I am struggling :(
Thank in Advance
json_decode() with TRUE as second parameter gives you an associative array. You need to access the correct index to do what you want.
To list the complete associative array with nice formatting, you can do:
echo '<pre>', print_r($arr), '</pre>';
Now, to access the name in your array:
$man = $arr['cards'][0]['name'];
To check if it's Batman (yay!):
if( isset($man) && $man == 'batman' ) {
# code ...
}
For getting the name of all similar names:
$man = $json['cards']['0']['name'];
for ($i=0; $i < count($json['cards']); $i++) {
echo $json['cards'][$i]['name']."\n";
}
See it live!
when you got the array
$arr = json_decode($json_raw, TRUE);
then check if cards key exist
if(array_key_exists('cards', $arr)){
foreach($arr['cards'] as $key=>$val){
echo $key; ///name, id..
echo $val; /// batman,...
if($key == 'name' && $val =='batman'){
//-------do your stuff
}
}
}
Try with:
$cards = $arr['cards'];
foreach($cards as $card) {
if($card['name'] == 'batman') echo 'Hello batman!';
}
EDIT:
Ok, so this worked for me using code above, try it yourself if you want:
<?php
$json_raw = '{"status":"OK","cards":
[{"id":100001,"name":"batman","image":11111,"size":75,"region_id":1,"locked":false,"status":"active","created_at":"2013-08-15T11:37:07Z"},
{"id":100002,"name":"superman","image":111111,"size":75,"region_id":1,"locked":false,"status":"active","created_at":"2013-08-15T12:30:09Z"},
{"id":100003,"name":"catwoman","image":1111111,"size":75,"region_id":1,"locked":false,"status":"active","created_at":"2013-08-15T12:39:42Z"},
{"id":100004,"name":"bane","image":1111111,"size":75,"region_id":1,"locked":false,"status":"active","created_at":"2013-09-08T12:56:04Z"}
]}';
$arr = json_decode($json_raw, TRUE);
$cards = $arr['cards'];
foreach($cards as $card) {
if($card['name'] == 'batman') echo 'Hello batman!';
}
?>

Create subset of php array and convert to json

This is one of those that should be easy. I'm not even sure if "subset" is the right way to describe it.
My initial array looks like this:
array(3) { [0]=> array(5) { ["id"]=> string(1) "1" ["claim_id"]=> string(1) "1" ["price"]=> string(2) "50" ["date"]=> string(19) "2013-05-15 01:58:48" ["created"]=> string(19) "2013-05-15 01:58:48" } [1]=> array(5) { ["id"]=> string(2) "11" ["claim_id"]=> string(1) "1" ["price"]=> string(2) "45" ["date"]=> string(19) "2013-05-15 03:34:59" ["created"]=> string(19) "2013-05-15 03:37:01" } [2]=> array(5) { ["id"]=> string(2) "25" ["claim_id"]=> string(1) "1" ["price"]=> string(2) "50" ["date"]=> string(19) "2013-05-15 22:47:46" ["created"]=> string(19) "2013-05-15 22:52:02" } }
I'd ultimately like to end up with just the date and price values, swap them so that date is first in the array, reformat the date, and convert it to a json array that looks something like this:
[{"date":"Mar. 15","price":"50"},{"date":"Mar. 15","price":"45"},{"date":"Mar. 15","price":"50"}]
I ran a foreach statement to get at the data and reformat the date, then went out of my league with splice, unset, and other functions that took me in the wrong direction. Any ideas?
Try this
$array = array();
for($i = 0 ; $i<count($your_array);$i++) {
$a=array();
$a['date'] = $your_array[$i]['date'];
$a['price'] = date("F .j",strtotime($your_array[$i]["date"]));
array_push($array,$a);
}
json_encode($array);
Output
[{"date":"Mar. 15","price":"50"},{"date":"Mar. 15","price":"45"},{"date":"Mar. 15","price":"50"}]
Codepad
This should get you there
$ret = array();
foreach ($source as $rec){
$ret[] = array("date"=>$rec["date"], "price"=>$rec["price"]);
}
$json = json_encode($ret);
Create a quick function to create another array with only selected elements:
function datePriceToJson($array) {
$a = array();
foreach($array as $i => $a) {
$a[] = array("date" => $a['date'], "price" => $a['price']); //Creae a new array based on the one you want
}
return json_encode($a);
}
datePriceToJson($array);
You need to reconstruct array using correct foreach and the use json_encode to get the json
$req_array = array();
foreach($youArray as $value)
{
$temp = array();
$temp['date'] = $value['date'];
$temp['price'] = $value['price'];
$req_array[] = $temp;
}
$json = json_encode($req_array);
echo $json;
see demo
Hope it helps you
$infos =array(
array("id" =>"1","price"=>"50","date"=>"2013-05-15 01:58:48"),
array("id" =>"2","price"=>"55","date"=>"2013-06-15 01:58:48")
);
$i=0;
foreach ($infos as $info )
{
$infos[$i]["date"]= date("F .j",strtotime($info["date"]));
$i++;
}
echo json_encode($infos);
