FATAL ERROR未捕获错误：无法使用stdClass类型的对象作为数组

Question

I have an array such as this which I get from a database query:

$arrname
Array (
    [0] => stdClass Object (
        [name] => Mike teach
        [age] => 67
        [gender] => Male
    )
    [1] => stdClass Object (
        [name] => Logan Pierce
        [age] => 45
        [gender] => Male
    )
    [2] => stdClass Object (
        [name] => Erikka Menh
        [age] => 60
        [gender] => Female 
    )
);

Now I want to append to this array and assuming they were like a 100 rows. I can't do that manually right? So I tried using this code:

foreach($arrname as $key => $value){
    $line = json_decode($value);
    $line['country'] = 'Us';        
    $line['occupation'] = 'Retired';
    $arrname[$key]  = json_encode($line);
}

echo $arrname[0]['country'];

Please I'd appreciate some help.

Answer 1

change this code:

foreach($arrname as $key => $value){
$line = json_decode($value);
$line['country'] = 'Us';        
$line['occupation'] = 'Retired';
$arrname[$key]  = json_encode($line);
}

echo $arrname[0]['country'];

to this:

foreach($arrname as $key => $value){
    $line = (array) $value;
    $line['country'] = 'Us';        
    $line['occupation'] = 'Retired';
    $arrname[$key]  = (object) $line;
}

echo $arrname[0]->country;

the json_encode function convert the array to a string type Javascript Object and json_decode does viceversa read http://php.net/manual/en/function.json-encode.php

If you wanna have a objects, you should use it like that

[1] =>  new stdClass Object (
        'name' => 'Logan Pierce',
        'age' => 45,
        'gender' => 'Male'
    )
