1.2.835. No Spread For Hash¶
The spread operator
...only works on integer-indexed arrays.
<?php
// This is valid, as ``"-33"`` is cast to integer by PHP automagically
var_dump(...[1,"-33" => 2, 3]);
// This is not valid
var_dump(...[1,"C" => 2, 3]);
?>
See also Variable-length argument lists.
1.2.835.1. Suggestions¶
Add a call to array_values() instead of the hash
Check the arguments beforehand with array_is_list()
Upgrade to PHP 8.1
