>Solution :

you have an array in json format:

 $array='[{"id":54,"systemid":"1610000060000000063"}]';

first you have to decode the array:

$decodedArray=json_decode($array);

then get the element at index 0:

    $object=$decodedArray[0];

then you can get it’s id:

    $id=$object->id;

see the sandbox for it:
