PHP syntax for arrays: different behaviour between PHP versions

Question

I made a PHP page with an array using the following syntax:

$Legenda = [
    \"Cores\"      => [\"#FF0000\", \"#FFA500\", \"#FFFF00\", \"#64FF00\", \"#00A

The shortened array syntax was only added in PHP 5.4: Arrays

As of PHP 5.4 you can also use the short array syntax, which replaces array() with [].

<?php
$array = array(
    "foo" => "bar",
    "bar" => "foo",
);

// as of PHP 5.4
$array = [
    "foo" => "bar",
    "bar" => "foo",
];
?>
