Answer 1

For PHP 7

Accessing Object properties having numbers as property name. Mostly needed after casting array to object.

    $arr = [2,3,7];
    $o = (object) $arr;

    $t = "1";
    $t2 = 1;
    $t3 = (1);

    echo $o->{1};      // 3
    echo $o->{'1'};   // 3
    echo $o->$t;        // 3
    echo $o->$t2;       // 3
    echo $o->$t3;       // 3

    echo $o->1;       // error
    echo $o->(1);      // error
