Update JSON Object PHP

Question

I want to update my JSON object according to user input using PHP , my JSON file looks like this :

[
  {
    id=1,
    text= "Sam",
  },
  {
   id=2,
    text= "Jack",
  }
]

I want to update the text with what the user will input

use json_decode() to turn your json string to a PHP array, then update it. — catcon

Kindly check your json format because it is not valid. This is my code, hope this will help you.

//your input
$id = 1;
$input = "john";

//decode your json
$info = json_decode($json);
foreach ($info as $data) {
    if ($data->id == $id) {   //find the id
        $data->text = $input; //update json object text depends on the user input
    }
}

then you can return the info to display update

return $info;
