modify date format on json array in php

Question

My issue is that I have array how contain value with dateTime format but I would like modify this value with a format Y-m-d. I tried a lot of thing of issue here but nothing work when I encode my json.

Now I have that :

[contacts] => Array (
                    [0] => Array (
                     [createdAt] =>2020-01-29T17:00:04.159+01:00
                   )
)

And I would result like

[contacts] => Array (
                    [0] => Array (
                     [createdAt] =>2020-01-29
                   )
)

My php code is :

$contacts=$result[contacts];
foreach ($contacts as $contact) {

$time = new DateTime($contact['createdAt']);
$date = $time->format('Y-m-d');
echo '<br>' .$date; //that show the date format I want
}
//that don't show correct format
 $json=json_encode($contacts);
 print_r($json);

Someone can help me ?

Could you please provide your code?

You can modify you $contact array with reference &:

foreach ($contacts as &$contact) {

    $time = new DateTime($contact['createdAt']);
    $contact['createdAt'] = $time->format('Y-m-d'); 
}

You can reassign value in your contact array by just doing below changes in your code

        foreach ($contacts as $key => $contact) {
            $time = new DateTime($contact['createdAt']);
            $date = $time->format('Y-m-d');
            echo '<br>' .$date; //that show the date format I want
            $contacts[$key]['createdAt'] = $date;
        }

it will reassign your new date value in your existing element
