I'm using json_encode on an object and stored on a hidden text field, When i was passing to the next page i didn't get any data
Code:
$flight = json_encode($od->FlightSegments);
Response page:
<?php print_r($_POST); ?> printed Array ( [flight] => { )
serialize and unserialize not working on my object.
Can any one tell me what's going wrong ?
To see XML literally on the web page, use:
<?php echo '<pre>' . htmlentities(print_r($_POST, true)) . '</pre>'; ?>
Since serialize and unserialize are not giving me the correct output for me, I solved my problem using below code.
$count = 0;
$_SESSION['fl'] = [];
foreach($response->Response__Depart->OriginDestinationOptions->OriginDestinationOption as $od){
$flight = json_encode($od->FlightSegments);
$_SESSION['fl'][$count] = $flight;
}
Stored entire object into a session array

I run the following PHP after I submit a form and get the output shown below:
$data = json_encode($_POST);
// output
{"First_Name":"Fred"}
How do I use PHP to just display the value 'Fred'?
I tried echo $data['First_Name']; but this is blank.
You no need to encode your incoming $_POST data.
Just say:
echo $_POST['First_Name'];
If you get a json data, decode it into an array:
$data = '{"First_Name":"Fred"}';
$decoded = json_decode($data, true);
echo $decoded['First_name'];
First of all, don't know why you use json_encode on PHP Array, and try to access it like it's an array - because after json_encode it's a string.
You have to use json_decode($data, true) and then you can access it like $data['First_Name'] or try to access it directly without json_encode() by $_POST['First_Name']
The json_decode() function is used to decode or convert a JSON object to a PHP object.And try to put the object to decode in another variable to avoid errors
<?php
$obj = '{"First_Name":"Fred"}';
$data = json_decode($obj);
echo ($data->First_Name);
?>
I'm having some problems getting the data through my PHP loop.
<?php
$url = 'https://www.fibalivestats.com/data/1653309/data.json';
$content = file_get_contents($url);
$json = json_decode($content, true);
?>
<?php
foreach($json['totallds']['sPoints'] as $item); {
echo $item;
}
?>
The error I'm getting is an array to string conversion error. What I'm trying to get is the data from the sPoints array that will give me a Top 5 points scorers for a basketball game.
I'll build a table for this in HTML later but for now, it's not displaying the data at all and I'm getting errors. I feel like I may have confused arrays and strings too. Any thoughts about what I'm doing wrong? JSON file can be found in the $url variable.
Also if it helps, here's the link to where I have gotten the data from and what context the Top 5 is from https://www.fibalivestats.com/u/NSS/1653309/lds.html
Thanks!
Your $item is an array, so you can't just echo it like that. You can, however, echo its columns, for example:
foreach($json['totallds']['sPoints'] as $item) {
echo $item['firstName'] . ' ' . $item['familyName'];
}
Notice the removed semicolon between the foreach () and {.
Well, array to string conversion error means you're trying to echo an array.
If you see the return of the url you are looking at, you can verify that the "sPoints" key returns an array with several objects.
Try to change echo to print_r or var_dump to view entire data or complete your business logic.
Try changing:
echo $item;
to:
var_dump($item);
I am trying to make a php page tp print json data for this i m using one paraeter for which i needed to fetch json from another url.I used the code given in other stackoverflow ans but it always giving 0.I tried everything but it always giving 0.My php code is:
<?php
if(isset($_POST['add']))
{
require_once('loginConnect.php');
$bookname=$_POST['bookname'];
$url = "http://example/star_avg.php?bookName=$bookname";
$json = file_get_contents($url);
$json_data = json_decode($json,TRUE);
echo 'data' + $json_data->results[0]->{'num'};
?>
My json data from other url is:
{"result":[{"avg":"3.9","num":"3"}]}
You see 0 printed because you're performing an addition + between the string data and a non-existent property. In PHP, to concatenate strings, do not use +; instead, use the dot . operator
In addition, because you're using true as the 2nd parameter to json_decode, what you get back is an array of arrays. Use the array notation [] rather than the object notation -> to access members.
$json_data = json_decode($json,TRUE);
$num = $json_data['result'][0]['num']; //<- array notation
echo 'data: '.$num; //prints data: 3
Live demo
below is my 'script.json' file with json array and i want the values of webUserid and webPassword
{
"totalSize":2,
"webUserId":"abc",
"webPassword":"def",
"operation":"send",
"testMode":true,
"records":[
{
"phoneNumber":"1908908399",
"message":"Happy Birthday",
"Id":"a0YL0000008QYunMAG",
"deviceId":"ABCDEFXABCDEF"
}
]
}
I tried below one but not getting the result
<?php
$jsonString=file_get_contents("script.json");
$decoded=json_decode($jsonString,true);
foreach($decoded->data as $name){
echo $name->totalSize;
}
?>
Zarif, try the below code, its working 100%......... :)
<?php
$jsonString=file_get_contents("script.json");
$decoded=array(json_decode($jsonString,true));
foreach($decoded as $name){
echo $name['totalSize'];
}
?>
There's no need for a foreach loop in your current example, as you only have one level.
Your main problem is you're trying to use the result of your json_decode as an object when you've previously stated you want the result as an associative array.
The 2nd param of json_decode specifies what format the return value is in, so as you've done
$decoded = json_decode($jsonString, true);
you'll receive an array, which you could access like
echo $decoded['totalSize'];
if you wanted to treat it as on object as you've done in your question, either state false or omit a 2nd param in json_decode (it's false by default anyway), and that'll let you do what you're trying to do:
$decoded = json_decode($jsonString);
$decoded->totalSize;
lets say that
$myJSON = yourPostedJSON.
$myJSON = json_decode($myJSON, true);
echo $myJSON['webUserId'];
echo $myJSON['webPassword'];
I am really going crazy at the moment, i have the following serialized, however when i try to unserialized it returns false.
Serialized array:
Array
(
[0] => a:1:{i:0;s:9:"714443801";}
)
Current Code:
<?php
$votesArray = unserialize($Vzzz);
echo "<pre>";
print_r($votesArray);
echo "</pre>";
?>
You are not unserializing it:
try:
print_r(unserialize($votesArray[0]))
If you are storing the serialized string, then store like this:
$serialisedData = base64_encode(serialize($arr));
After Retrieving,
//to unserialize...
$arr = unserialize(base64_decode($serialisedData));
