Here is the code:

<?php 
$dtime = DateTime::createFromFormat("d/m/Y G:i:s", "15/03/2019 07:18:57");
echo $timestamp = $dtime->getTimestamp();
?>

but I want to do this to all the values ​​of "date".

json:

[{
  "id": "6326",
  "type": "0",
  "date": "15/03/2019 07:18:57",
  "message": "test",
  "count": 17
},
{
  "id": "6326",
  "type": "0",
  "date": "15/03/2019 07:18:57",
  "message": "test",
  "count": 17
}]

try like this :

$datas = json_decode("your_json_string", true);
foreach($datas as $key => $value) {
    $dtime = DateTime::createFromFormat("d/m/Y G", $value['date']);
    $timestamp = $dtime->getTimestamp();
    $datas[$key]['date'] = $timestamp;
}
