Im trying to json_decode the following:
"main":{
"temp":9.04,
"temp_min":9.04,
"temp_max":9.04,
"pressure":938.13,
"sea_level":1037.57,
"grnd_level":938.13,
"humidity":87
},
"weather":[
{
"id":801,
"main":"Clouds",
"description":"few clouds",
"icon":"02d"
}
],
$result = json_decode($json);
$temp = $result->main->temp; //is displaying the data
however
$id = $result->weather->id; //is not displaying anything
all i can see is difference that te second one have an extra "[]"
can you help me telling how can i get weather->id from that json, thank you

The weather element is an array: it contains a list of elements. To get what you want from that exact example you would want:
$id = $result->weather[0]->id;
You also might want to think about what you want to happen if there is more than one element in that array, or if there are zero.

When i run my code it gives me extra square brackets in Response, and i want to get response without these SQUARE Brackets.
Respose which i am getting is below.
{"error":false,"message":"Login successfull","user":[{"u_id":"102","cust_name":"new","u_name":"user","cnic":"421","address":"sadaddd","cell_num":"43243","email":"n#gmail.com"}]}
Response which i want must be that: {"error":false,"message":"Login successfull","user":{"u_id":102,"cust_name":"new","u_name":"user","cnic":"421","address":"sadaddd","cell_num":"43243","email":"n#gmail.com"}}
My Code Section is below:
$user_login = $conn->prepare("SELECT u_id,cust_name,u_name,cnic,address,cell_num, email FROM users,cell_num WHERE u_name = :u_name AND password=:password AND users.u_id=cell_num.u_id_fk");
$user_login->execute(['u_name' => $u_name,'password'=>$password]);
if($user_login->rowCount() > 0){
$row = $user_login->fetchAll(\PDO::FETCH_ASSOC);
$response['user'] = $row;
//echo $row;
//print_r($row);
The square brackets means it is an array of data it's giving you rather than just one object.
Using fetchAll() will always return an array of rows matching the SELECT, if you know there is just one row, then you can use fetch() instead...
$row = $user_login->fetch(\PDO::FETCH_ASSOC);

I want to write a little webapp that will show some data. The data comes from an API. All data from the API I get displayed, but if I only want to display specific data, I always get an error.
I have not had much experience with API's yet, but all the tutorials I've done show the data via this echo method.
My current code:
<?php
$user_id = "3bb8d3bc-ab7a-45fb-8154-ed54897b2c4c";
$api_response = file_get_contents('https://r6tab.com/api/player.php?p_id='.$user_id);
$api_response_decoded = json_decode($api_response, true);
//foreach($api_response_decoded as $val) {
//echo $val, '<br>';
//}
echo $api_response_decoded->p_name;
?>
api_response Output:
"playerfound":true,"social":{"twitter":"","instagram":"","mixer":"","twitch":"","youtube":"","bio":"","esl":"","discord":"","background":"","aliases":"","embed":""},"seasonal":{"current_NA_mmr":0,"last_NA_mmr":0,"last_NA_mmrchange":0,"current_EU_mmr":3831,"last_EU_mmr":3881,"last_EU_mmrchange":-50,"current_AS_mmr":0,"last_AS_mmr":0,"last_AS_mmrchange":0,"total_casualwins":6,"total_casuallosses":5,"total_casualtotal":11,"total_casualkills":28,"total_casualdeaths":18,"total_rankedwins":38,"total_rankedlosses":24,"total_rankedtotal":62,"total_rankedkills":244,"total_rankeddeaths":201,"total_generalwins":44,"total_generallosses":29,"total_generaltotal":73,"total_generalkills":272,"total_generaldeaths":219,"total_totalbulletshits":3851,"total_totalhs":172,"total_totaltimeplayed":0,"bomb_wins":67,"bomb_losses":41,"bomb_total":108,"secure_wins":0,"secure_losses":0,"secure_total":0,"hostage_wins":1,"hostage_losses":0,"hostage_total":1,"favorite_mode":"bomb"},"matches":[{"casual_wlstatus":"won","casual_winslost":"1 Won","casual_datatime":"10\/02\/19","ranked_wlstatus":"won","ranked_winslost":"6 Won, 2 Lost","ranked_datatime":"10\/02\/19","next":"default","db_p_total_casualwins":1,"db_p_total_casuallosses":0,"db_p_total_casualkills":2,"db_p_total_casualdeaths":2,"db_p_total_rankedwins":6,"db_p_total_rankedlosses":2,"db_p_total_rankedkills":23,"db_p_total_rankeddeaths":23,"db_p_total_totalhs":10,"db_p_NA_currentmmr":0,"db_p_EU_currentmmr":3881,"db_p_AS_currentmmr":0,"NA_mmrchange":0,"EU_mmrchange":189,"AS_mmrchange":0},

By using the true flag on json_decode, you're creating an associated array instead of an object. Remove that flag, and you'll be able to use the object methods:
$api_response_decoded = json_decode($api_response);
echo $api_response_decoded->p_name; //Scenus
If you want to keep it as an associated array, you can access the data like this:
echo $api_response_decoded['p_name'];
when use json_decode('dsfsdf', true);
$p_name = $api_response_decoded['p_name'];
when use json_decode('dsfsdf);
$p_name = $api_response_decoded->p_name;

I have a very simple web app that is capturing RFID tag reads and then submits it into the Database.
I have a function that was to pass the information through a filter and remove the duplicates and then return an array of unique tag reads.
The function looks like this
$txtarea = $_POST["rfid"];
rfid($txtarea);
function rfid($txtarea){
$array = explode("\r\n", $txtarea);
$rfid_array1 = array_unique($array);
return $rfid_array1;
}
I then use Print_r to check the contents of the array to make sure it works.
When I run the code inside the function I do not get a result returned but when I run the following outside the function
$txtarea = $_POST["rfid"];
rfid($txtarea);
$array = explode("\r\n", $txtarea);
$rfid_array1 = array_unique($array);
It returns the values correctly ?
I am very new to PHP so I apologize if this question seems a little basic.
The function rfid returns a value which you could capture in a variable.
$rfid_array1 = rfid($txtarea);
Note that you could shorten the function a bit:
function rfid($txtarea){
return array_unique(explode("\r\n", $txtarea));
}

The title is a bit confusing, but the error which I have is -
$xml="<Contacts>";
for($i=0;$i<count($results['records']);$i++){
$xml. = "<Contact>
<Name>".$results['records'][$i]['name']."</Name>";
}
$xml.="</Contacts>";
When I try to add something to string (concatenate) I get 500 Internal server error. I believe that problem is in " $results['records'][$i]['name']". I think the solution is to replace JSON value with variable and enclose it in {}...maybe I am wrong, i don't know.
UPD:
if I "echo ".$results['records'][$i]['name'].""; It works fine.
You have a string concatenation (.=) syntax error. Change
$xml. = "<Contact>
to
$xml .= "<Contact>
I'm strictly answering the question about the "string concatenation" PHP error. No downvotes for anything except this point, please. But yes, try not to generate XML manually. I closed </Contact>s for you below.
$xml="<Contacts>";
for ($i = 0; $i < count($results['records']); $i++) {
$xml .= "<Contact><Name>".$results['records'][$i]['name']."</Name></Contact>";
}
$xml.="</Contacts>";

Trying to fetch the first URL field from an array of them that comes from a JSON I have decoded but I get this error:
Parse error: syntax error, unexpected '[' in C:\blabla
foreach($data-> images as $data2) {
print_r(images[0]['url']);
}
I hope its enough of my code to work out what I am doing wrong?
Added: I would like the first "url" and it was getting the last one hence why I am changing the code and trying to debug it here.
Within your foreach you use the variable name you specified in the definition:
So something like...
foreach($data->images as $data2) {
print_r($data2[0]['url']);
}
Although, depending on the structure of the array, I'd imagine that you don't need the number, so it might be:
foreach($data->images as $data2) {
print_r($data2['url']);
}
If you wanted to loop through the values by a number, you'd use a for loop
for ($i = 0; $i <= count($data->images); $i++)
{
print_r($data->images[$i]);
}
