PHP var_export() with short array syntax (square brackets) indented 4 spaces

varexport.php

<?php
function varexport($expression, $return=FALSE) {
    $export = var_export($expression, TRUE);
    $export = preg_replace("/^([ ]*)(.*)/m", '$1$1$2', $export);
    $array = preg_split("/\r\n|\n|\r/", $export);
    $array = preg_replace(["/\s*array\s\($/", "/\)(,)?$/", "/\s=>\s$/"], [NULL, ']$1', ' => ['], $array);
    $export = join(PHP_EOL, array_filter(["["] + $array));
    if ((bool)$return) return $export; else echo $export;
}

Empty objects in PHP 8.0.30 at least are var_exported as

array (
  'key' => 
  (object) array(
  ),
)

This syntax is not handled correctly by this script.
