1.2.582. Integer As Property¶
It is backward incompatible to use integers are property names. This feature was introduced in PHP 7.2.
If the code must be compatible with previous versions, avoid casting arrays to object.
<?php
// array to object
$arr = [0 => 1];
$obj = (object) $arr;
var_dump(
$obj,
$obj->{'0'}, // PHP 7.2+ accessible
$obj->{0} // PHP 7.2+ accessible
$obj->{'b'}, // always been accessible
);
?>
See also PHP RFC: Convert numeric keys in object/array casts.
