Insert JSON object into .json file using php

Question

I have the following JSON file stored in a server. I am using a php script to add another object to this JSON file.

testjson1.json:

{
"feed": 
[
{
"id": "1",
"name": "Ram",
"status": "Very good restaurant!! water tastes soo good :)"
}
]
}

The php that i use to add an object is as follows:

<?php
$data=array("2","new","not so good");
$inp = file_get_contents('testjson1.json');
$tempArray = json_decode($inp);
array_push($tempArray, $data);
$jsonData = json_encode($tempArray);
file_put_contents('testjson1.json', $jsonData);
?>

But the php file shows an error which says:

Warning: array_push() expects parameter 1 to be array, object given in /home/u160481344/public_html/jsonfinder.php on line 5

and the json file collapses into a single line. How can i solve this?

As per the documentation, if you don't want object from json_decode

   json_decode($tempArray, true);

Add second boolean parameter. Try and let me know.

Add second boolean parameter TRUE, returned objects will be converted into associative array.

Just replace this line

$tempArray = json_decode($inp);

With this

$tempArray = json_decode($inp,true);

PHP function json_decode() decodes a JSON string, it takes a JSON encoded string and convert it into PHP variable.

The script written below return a PHP variable in an object data type.

$inp = file_get_contents('testjson1.json');
$tempArray = json_decode($inp);

But PHP function array_push() accepts only array as input parameters. There is a second parameter (optional) boolean type you can pass into the json_decode() function like json_decode($json_string, TRUE) which will return decode PHP variable in an associative array. You have to update your code like this -

$inp = file_get_contents('testjson1.json');
$tempArray = json_decode($inp, TRUE);

For more reference see this link PHP function json_decode().
